1. Tested at 100 kHz, 0.1Vrms,
0 A
dc
bias.
2. Electrical specifications at
25°C.
3. Operating range: -40°C to
+155°C. This is a com-
bination of ambient plus
temperature rise.
4. Meets Class F (155°C) insula-
tion system requirements.
5. I
sat
is the DC current re-
quired to reduce the nominal
inductance by 30%.
6. I
dc
is the DC current required
to produce a temperature
rise of 50°C.
7. Meets UL 94V-0.
