6 Fetures of Jennings vcuum cpcitors High Voltge Rting The dielectric strength of the vcuum permits optimized voltge rting for given size nd cpcity, in ddition to freedom from contmintion, humidity nd oxidtion. High Current Rting Low losses nd rugged copper construction permit the hndling of high RF currents with convection cooling only. Some of our designs offer wter nd ir cooling for extrordinry lod conditions. Wide Tuning Rnges High rtio of mximum to minimum cpcity (up to 17:1) mke Jennings vcuum cpcitors desirble for wide tuning rnges. Low Losses Losses in vcuum cpcitor re so smll tht for most pplictions they cn be considered s negligible. Construction mterils nd the vcuum dielectric permit the hndling of lrge RF currents t high RF frequencies tht would destroy cpcitors with other dielectrics. Self-Heling Jennings vcuum cpcitors cn withstnd momentry overlods tht would permnently dmge other dielectric mterils. High Altitude Opertion Vcuum seling permits the opertion of Jennings vcuum cpcitors t high ltitudes without the degrdtion tht occurs with other types. Description nd Generl Specifiction Figure 1 illustrtes the construction of typicl Jennings vrible vcuum cpcitor. Two sets of concentric cylinder pltes, one djustble nd the other fixed, re enclosed in n evcuted cermic envelope with OFHC copper sels t both ends. A flexible metl bellows, ttched to sleeve-type bering, mintins vcuum while llowing cpcitnce to vry.

7 Current/Voltge Mximum operting current for vcuum cpcitors is limited by temperture rise nd working voltge. At lower frequencies, cpcitor is current-limiting device s result of its cpcitive rectnce. At some frequencies, the internl genertion of het exceeds the device s het-sinking cpbilities, nd its current-crrying cpcity is limited by therml considertions. A current vs. frequency chrt is provided for ech cpcitor listed. Pek voltge is limited by mechnicl design of the cpcitor. It does not vry with frequency. Temperture Jennings Technology vcuum cpcitors re designed to meet MIL-C-3183 specifictions. Our cpcitors re rted for mximum operting temperture of 1 C (7 F) with norml convection cooling t n mbient temperture of C (7 F). Current The current rting provided in the tbles in this ctlog is the mximum current the vcuum cpcitor t mximum working voltge cn hndle continuously under norml convection cooling t n mbient temperture of C. Pulse Rtings Continuous RF current rtings my be exceeded for short periods if the working voltge rting is not exceeded. This pplies prticulrly to pulse nd peks-of-modultion pplictions. Momentry currents my exceed the ctlog continuous current rting by fctor of the squre root of the duty cycle, provided the working voltge is not exceeded. High-current pplictions? Jennings PV Series cpcitors set new stndrd for vcuum vrible cpcitors. One of the ltest innovtions to emerge from Jennings Technology, the PV Series of vcuum vrible cpcitors ws designed to withstnd rugged, high-current environments to meet the incresing demnds of semiconductorprocessing pplictions. Jennings qulity engineers put the PV Series cpcitors through rigorous testing. All tested units chieved more thn. million cycles while still meeting their originl specifictions, nd mny exceeded 3.8 million cycles. For detiled test results, contct Jennings t 8-9- or visit com/technotes/high_rtings.shtml. Jennings offers PV Series vcuum vrible cpcitors in 0, 00 nd 00pF cpcitnce. Look for them on pges 3, nd 3 of this ctlog. Amplitude Modultion Rtings Cpcitors in AM service must be ble to withstnd peks-of-modultion voltge nd current. Current rtings re bsed on temperture, so the heting effects of the modulted currents determine the cpcitor requirements. The verge output power of n AM trnsmitter tht is 0% sine wve modulted is 1. times the unmodulted crrier power. The verge modulted crrier current is 1. times the unmodulted crrier current. Therefore, cpcitor current rting of 1. times the crrier current will be sufficient, even though the peks-of-modultion currents re twice the crrier current. w w w. j e n n i n g s t e c h. c o m

8 Forced Air Cooled nd Wter Cooled If higher current rtings re required, cpcitors re vilble with forced-ir cooled bellows to operte sfely t 0% of the convection-cooled rting. They re identified with CAV model number. Wter-cooled cpcitors, identified with model number beginning with CW, re lso vilble nd re normlly limited only by voltge. On stndrd convection-cooled cpcitors, current rting my be exceeded for short periods of time, providing the rted temperture rise is not exceeded. Under no conditions should the current exceed 1% of convection current rting. Fixed cpcitors cn crry more current becuse they hve shorter RF impednce pths. Fixed cpcitor current rtings my be incresed by forced-ir cooling up to voltge nd temperture limittions. Voltge Two voltge rtings re provided in our product specifictions: AC Test Voltge nd Working Voltge. AC Test Voltge is the mximum Hz voltge tht cn be pplied to the cpcitor without brekdown occurring, s indicted by either internl or externl rc-over. Cpcitors re tested t this voltge s mens of determining the generl condition of the cpcitor. Customers frequently use such test in incoming inspection to check for dmge in trnsit. Externl rc-over is usully n indiction of externl contmintion or high humidity, not deficient cpcitor. RF Working Voltge is the mximum pek RF voltge tht cn be pplied continuously to the cpcitor without ffecting its bility to withstnd instntneous overlods. It hs been estblished s % of the Pek Test Voltge rting. The difference between the Hz Test Voltge nd the Working Voltge vlues is the recommended operting sfety fctor. For vrible cpcitors, the voltge rting is essentilly constnt from mximum cpcity to point ner minimum cpcity, where it increses significntly. Within the norml ccurcy of instrumenttion (±3%), voltge rtings should not be exceeded. Jennings RF testing fcilities monitor the bove chrcteristics on 0% bsis, nd cn lso do specil ppliction testing when required. DC Vcuum cpcitors should not be operted t DC voltge bove the pek RF working voltge. DC plus RF For DC plus RF pplictions, the sum of the DC plus the pek RF voltge should not exceed the pek RF working voltge. Cpcitors for DC plus RF pplictions re tested for DC emission on dielectric strength tester. To meet Jennings Qulity Assurnce stndrds, the DC emission current must not exceed ten micromps t the rted working voltge. Amplitude Modultion The pek output power of n AM trnsmitter tht is 0% sine wve modulted is.0 times the unmodulted crrier power. The pek RF voltge will be twice tht of the unmodulted crrier, nd the cpcitor should hve n RF working voltge rting equl to or greter thn this voltge w w w. j e n n i n g s t e c h. c o m

9 Cpcitnce Fixed cpcitors with nominl cpcitnce bove pf shll be within ±%. Cpcitors with nominl cpcitnce of pf or less shll be within ±%, or. pf, whichever is greter. For vrible cpcitors, the low end will be equl to or less thn minimum rting. The cpcitnce chnge is substntilly uniform with rottion, nd there re no cpcitnce reversls. Cpcitnce is within ±% of the nominl vlue of the curves shown (Cpcity vs. ), in the liner portion of this curve. Automtic Shorting Feture Some vrible cpcitors hve been designed with n internl shorting device tht shorts out the cpcitor when it hs been turned beyond mximum rted cpcitnce. This feture is useful for tuning ntenn couplers without the vcuum cpcitor in the circuit nd lso serves s reference point for djusting the cpcitor to previously mesured cpcitnce vlue. Adjustble Cpcitors Jennings Technology cpcitors with model number beginning with CAC or CAD designtion re djustble cpcitors, designed to be operted s fixed cpcitor, but ble to be hnd djusted to ny vlue within their rnge nd then locked in position with locking nut. Trcking Pirs of vrible cpcitors will trck within % if set together ner the low cpcity end of the liner portion of the curve. On specil order, units my be obtined to closer trcking tolernces. Torque/Direct Pull In vrible cpcitors, the liner sliding motion of the moving electrode ssembly is converted to rotry tuning vi threded shft. The torque vlues given in the tbles re the mximum torque needed to rech minimum cpcitnce when rotted with stndrd led screw; the torque required to tune wy from minimum my be less thn hlf this vlue. For most vrible cpcitors, direct pull tuning is n vilble option to rotry tuning. Mximum required direct pull force vlues re lso given in the tbles. Cpcitnce rnge end-stops re built into every vrible cpcitor. It is recommended tht the user instll their own externl stops to prevent dmge from ger-reduction drives. Qulity Fctor (Q) Extremely low losses occur in vcuum cpcitors becuse of the vcuum dielectric, compct construction nd use of lowloss cermic envelopes, s well s copper nd precious-metl solder construction. Consequently, vcuum cpcitors re ble to hndle lrge RF currents t high RF frequencies tht would destroy other types of cpcitors. The Q fctor, or rtio of stored energy to dissipted energy, is typiclly in the order of 00 to 00 nd higher. Equivlent Series Resistnce (ESR) Becuse Q is function of frequency, cpcity nd ESR (Equivlent Series Resistnce), it is perhps more meningful to consider the vlue of ESR. In modern high power cpcitor pplictions, ESR is significnt for determining cooling requirements. The slight loss results from the RF resistnce in the copper. Bsed on ctul tests, the ESR vlue is not ffected by chnge in cpcity, other prmeters being fixed. The vlue of ESR vries over rnge of to milliohms from to MHz. w w w. j e n n i n g s t e c h. c o m

Indicted by model number tht begins with M/, Jennings Jenn-X vcuum vrible cpcitors re vilble in 0pF nd 00pF mximum cpcitnce. Look for them on pges 3 nd 9 of this ctlog. Therml Stbility Jennings vcuum cpcitors re designed to meet MIL-C-3183 specifictions, which stte tht the bsolute vlue of the cpcitnce chnge with temperture shll not exceed 1.1% over the pplicble operting temperture rnge. In typicl tests, vlues for cermic cpcitors show stbility within ppm/ C. Slt Spry nd Humidity Jennings cpcitors re designed to withstnd the hrmful effects of slt spry nd humidity without degrdtion in performnce. Inductnce The self-inductnce of vcuum vrible cpcitors is typiclly in the order of to nnohenries, while tht of fixed cpcitor is significntly lower, in the rnge of to nnohenries. For most pplictions, the selfinductnce cn be ignored. It becomes fctor only when the rtio of cpcitive rectnce to inductive rectnce is smll. Mechnicl Life The mechnicl life of vrible cpcitors is relted to length of stroke, speed of opertion, bellows mteril nd totl number of cycles. Extensive mechnicl life tests hve been run, operting units for complete cycles from mximum to minimum nd bck to mximum cpcity covering 9% of the full stroke of the movble pltes. Cpcitors with lrge bellows nd short stroke will hve the gretest life expectncy under cycling opertion. Our most recent vrible cpcitor models re rted for > 3 million cycles, idel for the semiconductor processing industry.

11 Cpcitors in Prllel POOR When two or more cpcitors re connected in prllel, the inductnce of the connecting conductors cting with the cpcitors form tuned circuit. CAPACITOR In high current circuits, it is possible to prllel two or more vcuum cpcitors to increse cpcity. Cre must be tken, due to the low loss of the vcuum cpcitors nd the hevy copper strps prlleling the cpcitors, to ensure tht the frequency of this series high-q resonnt circuit is bove the operting frequency. If the frequency of the series resonnt circuit is llowed to become equl to the operting frequency, high currents will be generted, resulting in dmge to the cpcitor. FLAT STRAP BETTER CAPACITOR All vcuum cpcitors hve inductnce within the connections (Figure 3). The resulting tuned circuit of two 00pF cpcitors in prllel cn be kept well bove MHz. At low cpcities of to 0pF, the resonnt frequency cn be kept well bove 0 MHz. Figure is grph of resonnt frequency vs. cpcity of two 00pF cpcitors with low inductnce connections. The resonnt frequency of the resulting prellel tuned circuit vries from MHz to 13 MHz from mximum to minimum cpcity. Testing Stndrds Fctory All cpcitors re tested for dielectric strength on 0% bsis prior to shipment. Upon customer request, certified test reports will be mde vilble. Dielectric strength is tested using low current, high potentil source t Hz voltge. BUCKING LOW INDUCTANCE CONNECTOR PAN OR DISH TYPE Figure 3 Vcuum Cpcitors with Inductnce within the Connections for Better Performnce 0 0 RESONANT FREQUENCY TWO 00pF CAPACITOR WITH LOW INDUCTANCE CONNECTORS (With stndrd strp connectors the frequency is pproximtly % lower) Cpcitnce (pf) Figure Resonnt Frequency vs. Cpcity Cpcitors for pplictions involving pplied DC voltge should be tested on DC dielectric strength meter for voltge nd emission current. Jennings will test cpcitors to this mesure if specified by the customer. User Most users will find the Hz dielectric strength test dequte nd reltively inexpensive. Jennings does not recommend DC testing being performed by the user becuse of sfety considertions. If DC testing is performed, cre should be tken not to exceed % of the pek test voltge rting of the cpcitor. w w w. j e n n i n g s t e c h. c o m

12 Testing Procedure Apply Hz current-limited voltge cross the cpcitor. One side my be grounded if desired. Increse voltge grdully. The rte of increse should be from zero to mximum voltge in one minute. Norml test procedure requires tht the cpcitor be ble to withstnd the full rted voltge without brncles (rcing) occurring fter the first minute t the test voltge. A brncle is self-heling, nonsustined, momentry brekdown. Wek brncles tht instntly hel re disregrded during the first minute. Under no condition should the test voltge be exceeded. Arc Detectors In extremely criticl circuit pplictions, some form of rc detection is necessry. An oscilloscope my be connected cross the cpcitor to show wek electron dischrges, wveform distortion, evidence of strong DC emission currents or coron. Another form of rc detection my be improvised by using smll neon lmp with one terminl connected to the hot side of the cpcitor under test nd the other terminl of the lmp floting. The lmp will flsh when the cpcitor rcs. A contct microphone nd udio mplifier connected to the bse of the stndoff insultor supporting the cpcitor under test lso mkes very sensitive rc detector. Instlltion Testing Jennings vcuum cpcitors re well pckged nd shipped in mnner to ensure sfe delivery. However, during shipping they my be subjected to extreme shock, which could dmge the cpcitor elements without dmging the shipping continer. Therefore, cpcitors should be tested upon receipt nd before instlltion. (See Cpcitor Testing Procedure bove.) HiPot Testing of Vcuum Cpcitors The most importnt test for vcuum cpcitors is the high voltge AC HiPot test. It is the indictor of the stndoff cpbility of cpcitor. If the vcuum level of cpcitor decys or there is mislignment of the pltes, the stndoff cpbility of the cpcitor will be reduced. This test is performed by pplying or Hz AC voltge up to the specified Test Voltge (ETest) of the cpcitor. The lower the frequency of HiPot test, the more stringent it is. Therefore, or Hz is used, even for cpcitors to be used in RF pplictions. Cpcitors to be used in DC pplictions should not be subjected to DC voltge bove the specified Operting Voltge, which is % of the Test Voltge. Personnel: Trined nd qulified to work sfely with high voltges. Equipment: HiPot tester tht is certified to meet pproprite government sfety stndrds or n pproved vrible AC power supply cpble of supplying the voltge required with current-limiting resistor (R ETest/Imx) in series between the power supply nd the cpcitor w w w. j e n n i n g s t e c h. c o m

13 Procedure: 1. Apply ~ 1 or Hz to the electrodes. Increse the voltge t rte of kv per minute up to ETest unless there is internl rcing (brncling) or current flow greter thn the chrging current of the cpcitor tht persists for > seconds. In tht cse, reduce the voltge until brncling termintes, observe voltge nd repet the process. Continue this process s long s the voltge where rcing is encountered continues to increse up to ETest.. If there is ny externl rcing t ny voltge, clen the externl surfces. If conditions re extremely humid, dely testing until it cn be done in lower humidity. 3. Upon experiencing ny brncling or current flow greter thn the chrging current of the cpcitor tht persists for > seconds, reduce voltge until brncling termintes, observe voltge nd repet the process. Continue this process s long s the voltge where rcing is encountered continues to increse up to ETest nd is held there for one minute without brncling or exhibiting current flow greter thn the chrging current of the cpcitor.. If there is no persistent brncling or current flow greter thn the chrging current of the cpcitor (up to ETest), the cpcitor hs pssed the HiPot test. If brncling is encountered, it is not necessrily bd cpcitor, but it my require reconditioning. Wrning During instlltion, void twisting or bending strins tht could cuse filure of the cermic-to-metl sel. Mounting Position Units my be mounted in ny position. When lrge cpcitors re mounted horizontlly, both ends should be supported by stndoff insultors to eliminte excessive stresses nd possible dmge. (Verticl mounting preferred.) Cooling Current rtings re determined on the bsis of convection cooling only. It is good design prctice to provide n dded sfety fctor by hving the vrible end mounted on the chssis for het sinking nd by using flexible copper strps for the fixed electrode end. When lrge cpcitor is being operted ner its mximum current rting t high frequencies, there must be dequte spce round the unit for convection cooling. Wter Cooling Consult fctory for specific recommendtions. w w w. j e n n i n g s t e c h. c o m

14 Vcuum Cpcitor Reconditioning A vcuum cpcitor tht hs exhibited brncling during incoming inspection, when it hs been in storge, or hs been used for light duty (low voltge) for prolonged period my exhibit internl rcing (brncling) when high voltge is first pplied. If this occurs ETest, it my be n indiction tht the cpcitor needs reconditioning or tht it no longer hs dequte voltge stndoff cpbility. In this sitution, we recommend the following course of ction. Personnel: Trined nd qulified to work sfely with high voltges. Equipment: HiPot tester tht is certified to meet pproprite government sfety stndrds or n pproved AC vrible power supply cpble of supplying the voltge required with currentlimiting resistor (R ETest/Imx) in series between the power supply nd the cpcitor. Procedure: 1. Apply ~ 1 or Hz to the electrodes. Grdully increse the voltge up to ETest unless there is internl rcing (brncling) or current flow greter thn the chrging current of the cpcitor tht persists for > seconds. In tht cse, reduce the voltge until brncling termintes, observe voltge nd repet the process. Continue this process s long s the voltge where rcing is encountered continues to increse up to ETest.. If there is ny externl rcing t ny voltge, clen the externl surfces. If conditions re extremely humid, dely testing until it cn be done in lower humidity. 3. Upon experiencing ny brncling or current flow greter thn the chrging current of the cpcitor tht persists for > seconds, reduce voltge until brncling termintes, observe voltge nd repet the process. Continue this process s long s the voltge where rcing is encountered continues to increse up to ETest. The cpcitor should be held t ETest for one minute without current flow or brncling. Leve ETest pplied for 1 to minutes to complete this session of conditioning.. If brncling is encountered t the sme voltge or lower for three successive ttempts, discontinue reconditioning. If the cpcitor is in wrrnty, cll Jennings Technology s QA Deprtment t (8) nd request n RMA number. Then return it to the fctory for evlution. If it is out of wrrnty, dispose of it in sfe mnner.. If conditioning s described in prgrphs 3 nd ws required, but it psses the one-minute test without current flow or brncling, llow it to rest for t lest hours nd repet the conditioning process for up to three sessions. If it psses the one-minute test described in prgrph 3 fter -hour hold, it is dequtely conditioned nd my be plced into service. If fter three sessions, the cpcitor continues to brncle, the cpcitor is probbly bd w w w. j e n n i n g s t e c h. c o m

15 Therml Expnsion To llow for therml expnsion, t lest one end of the vcuum cpcitor should hve flexible connection. In vrible cpcitors, the flexible connection is normlly mde to the fixed electrode end. Avoid hevy rigid strps or connections tht produce mechnicl strin. The connections should be of substntil re to keep losses low nd provide cooling by conduction from both ends. Only smll degree of flexibility is required. Electricl Connections Both ends of the cpcitor my be hot, or one end my be grounded. Becuse of the high voltges present, there must be sufficient clernce between the vcuum cpcitor nd other components to prevent high voltge brekdown. Although the cpcitors re designed to ensure optimum electricl field distribution, mounting should be such tht djcent components do not upset this norml electricl field nd thus result in excessive heting. Mgnetic Influences Strong mgnetic influences cn induce heting nd ffect performnce of cpcitors. Electromgnets hve greter effect thn permnent mgnets. Trnsients nd Prsitics Where the possibility exists of externl rcs from trnsients or prsitic voltges, the cpcitor should be protected by dequte coron, or rc shields. Bll gps re recommended when protection from simple voltge rc cover is required. Led Lengths At high frequencies, void long led length, becuse the rectnce of the strp will subtrct from the rectnce of the cpcitor nd effectively increse the totl cpcitnce. In some cses, the totl rectnce my be reduced to the point where the minimum cpcity of the cpcitor will pper too high. Side Loding Side loding (rdicl force pplied to led screw) will gretly ccelerte wer nd significntly reduce life. A flexible coupler connection to the led screw is highly recommended. Incresed frequency of 0% minimum to mximum cycling will lso be helpful. (See Mintennce.) Other Precutions Cpcitors should not be used s stndoff insultors to support hevy ssemblies. Only the prt of the cpcitor specified s the mounting re should be used for tht purpose, nd ny clmps or strps must be ttched crefully to void stress on the unit, possibly cusing sel filure. Solder connections should not be mde directly to the body of the cpcitor, nor should there be ny contct with the cermic insultor during opertion. Mintennce WARNING DISCONNECT POWER BEFORE SERVICING. HAZARDOUS VOLTAGE CAN SHOCK, BURN OR CAUSE DEATH. Cpcitors operted t norml temperture in clen environment require no mintennce except to keep them free of dirt ccumultion nd moisture tht my cuse drop in externl insultion resistnce. A specil glze is pplied to ll Jennings cermic cpcitors to void bsorption of moisture nd foreign mtter. For vrible cpcitor pplictions involving frequent djustment over limited rnge, such s semiconductor impednce mtching, it is dvisble to cycle completely between minimum nd mximum t lest cycles every,000 cycles to redistribute lubricnt. If vrible cpcitors re being operted t high tempertures, it is dvisble to periodiclly lubricte the shft nd bering with good grde of high temperture light oil nd the led screw with high temperture, extreme pressure grese. w w w. j e n n i n g s t e c h. c o m
