Transformateurs / transformers - Pulse Transformers - FAMILLE 68H14 69H14

CASE VERSION Ignition current up to 100 mA

These small size and low power transformers are fitted on toroid cores of high performance (ferrite).
The wide choice of inductance values and turn ratios make them suitable as drivers of thyristors, triacs,
bipolar transistors or MOSFET's in a variety of high frequency applications, such as small power
supplies, inverters etc., or also as couplers in high speed data trasmission.
