1. Tested at 10 kHz, 0.1Vrms
.
2. Electrical specifications at 25˚C.
3. Operating range: -40˚C to +130˚C.
4. Meets UL94V-0.
5. Select pin assignment option based on schematics above. For other options please contact ICE Components, Inc.
6. E-T product rating is for the secondary (gate) windings and is based upon a peak flux denisty of 2200 Gauss at
25°C when used in a bipolar-driven application.
Specifications subject to change without notice.
