(1) Test Parameters: 100 kHz,.0.25 Vrms 0.0 Adc

(2) Irms: DC current for approximately ΔT of 40 °C without core loss. It is recommended that the

temperature of the part not to exceed

+125 °C. Derating is necessary for AC currents

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

(4) DCR limits @ +20 °C

(5) Applied Volt-Time product (V-µ

s) across the inductor at 100 kHz necessary to generate a core loss equal

to 10% of the total losses for a 40 °C temperature rise. Derating of the Irms is required to

prevent excessive temperature rise.
