Transformateurs / transformers - Pulse Transformers - FAMILLE 64H27 68H27 69H27

CASE VERSION Ignition Current up to 1 A

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.
