These trasformers are woud o high quality ferrite core ad are iteded for a very wide rage of applicatios: firig thyristors ad triacs; drivig bipolar trasistor ad IGBT; drivig FET ad MOSFET trasistors; lie couplig i high speed data trasmissio (for the smallest sizes). Three case sizes are preseted, with icreasig power ratig, so that they ca effectively fid use as drivers i ay low-to-medium power circuit for cotrol ad coversio of electrical eergy, where the followig features are requested at the same time: high power pulse trasmissio capability (high amplitude with proper du) ad low magetizatio curret; low leakage iductace, wich allows high steepess ad short rise time of the wave form; low couplig capacitace, so that a good decouplig ad immuity to iterfereces is reached; small size, achivied with the use of toroidal core; high primary to secodary withstadig voltage by meas of a proper wires isulatio ad rosi fillig; iteal stadards compliace.
Symbol Defiitios Turs Ratio () Turs of the primary widig to each secodary widig; first digit refers to the primary. oltage-time Area () Miimum oltage-time product of the pulse amplitude ad pulse width, measured at half of the pulse height across the uloaded secodary i the uipolar mode. Primary Iductace ( Iduct) Iductace of the primary widig measured at 10 khz/0,1 ma (referece values oly) Primary Leakage Iductace ( Leak Iduct) Leakage iductace of the primary widig with secodary widig(s) coected i series ad short circuited; measured at 100 khz. Widig Capacitace (/ ) Couplig capacitace betwee primary ad secodary widig(s); measured at 10 khz. Primary Resistace ( ) DC resistace of the primary widig. Secodary Resistace ( ) DC resistace of (each) secodary widig. Test oltage () Urepeated test voltage at 0 Hz/1 to sec, betwee primary to secodary widig(s). Igitio Curret (I c) Referece curret value givig a low voltage - drop uder 1 - across the secodary resistace. Pulse Rise Time () Rise time betwee 10% ad 90% of the output pulse amplitude, measured o the secodary loaded with RL resistor. Secodary resistor load (RL) Workig oltage () Maximum rms workig voltage of primary widig.
CASE ERSION Igitio curret up to 100 ma These small size ad low power trasformers are fitted o toroid cores of high performace (ferrite). The wide choice of iductace values ad tur s make them suitable as drivers of thyristors, triacs, bipolar trasistors or MOSFET's i a variety of high frequecy applicatios, such as small power supplies, iverters etc., or also as couplers i high speed data trasmissio.
