Operating Temperature

-55°C to +200°C;

-55°C to +160°C @ full rated current

All materials are rated to +200°C

Current Rating at 160°C Ambient 40°C Rise

Inductance Measured @ 1 V, 100mA AC with no

DC Current. Inductance at +200°C is typically

5.5% lower than inductance measured at +25°C.

Incremental Current The current at which the

inductance will be decreased by a maximum of

10% from its initial 0 DC value. At elevated

temperatures incremental current is unaffected.
