Type MLS 125 C Flatpack, Ultra Long Life, Aluminum Electrolytic Now Available with High Vibration and High Reliability Options

Transcription

1 Now Encased in rugged stainless steel, the MLS is perfect for high reliability military systems and applications operating above 85 C. For our highest performing 25 C Flatpacks, choose type HVMLS available in a special stainless steel case for high vibration applications up to 5g. Specify type HRMLS for high reliability Flatpacks which are subjected to MIL level burn-in processes to ensure established reliability.

The optional welded mounting tabs, alone, are not capable of sustaining the high vibration levels. To achieve the high vibration levels as published on right, additional mounting restraint is required. Standard MLS Flatpack: g Hz to 2 khz Sine Swept,.6 pp max and g.

2 Vibration Test Level The specimens, while deenergized or operating under the load conditions specified, shall be subjected to the vibration amplitude, frequency range, and duration specified for each case size. Amplitude The specimens shall be subjected to a simple harmonic motion having an amplitude of either.6-inch double amplitude (maximum total excursion) or peak level specified above (XXg peak), whichever is less. The tolerance on vibration amplitude shall be ± percent. Frequency Range The vibration frequency shall be varied logarithmically between the approximate limits of to 2, Hz. Sweep Time and Duration The entire frequency range of to 2, Hz and return to Hz shall be traversed in 2 minutes. This cycle shall be performed 2 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 2 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met. High Reliability Test/Burn-in Established Reliability capacitors shall be subjected to a minimum of percent of the dc rated voltage at 85 ºC for 48 hours minimum but not to exceed 96 hours. During this test, capacitors shall be adequately protected against temporary voltage surges of percent or more of the test voltage. After burn-in, the capacitors shall be returned to room ambient conditions and the dc leakage, capacitance, and ESR shall be measured with respect to specified limits. Thermal Resistance Large Sides Heatsinked one both Case Length.5" 2." 3."

The ripple currents in the ratings tables are for 85 ºC case temperatures. For air temperatures without a heatsink use the multipliers Ambient Temperature, No Heatsink. Temperature rise from the internal hottest spot, the core, to ambient air is T = I 2 (ESR)(θcc + θca) where θcc is the thermal resistance from core to case and θca from case to ambient. To calculate maximum ripple capability with the MLS attached to a heatsink use the maximum core temperature and the values for θcc. As an illustration, suppose you operate an insulated MLS332M6EBC in 65 ºC air and attach it to a commercial heatsink with a free-air thermal resistance of 2.7 ºC/W. Use a good thermal grease between the MLS and the heatsink, and the total thermal resistance is or 4.5 ºC/W. The power which would heat the core to 25 C is (25-65)/4.5 or 3.3 W. For an ESR of 3 mω, 3.3 W equates to a ripple current of 2.7 A, however, the wire leads are rated for only 2 A. CDM Cornell Dubilier 4 Technology Place Liberty, SC Phone: (864) Fax: (864)843-38
