1 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.

2 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.

3 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.
