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.
