Notes: (1) Open Circuit Inductance Test Parameters: 100

kHz, .250 Vrms, 0.0 Adc.

(2) RMS current for an approximate ∆T of 40 °C without core loss, at an

ambient temperature of

+85 ˚C.

(3) Peak current for approximately 30% rolloff @ +20 °C.

(4) DCR limits +20 °C.

(5) Applied volt-time product (V-us) across the inductor.This value

represents the applied v-us at 300

kHz necessary to generate a core

loss equal to 10% of the total losses for a 40 °

C temperature rise.
