(1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc.

(2) RMS current for an approximate

∆T

of 40°C without core loss. It is

recommended that the temperature of the part not exceed 125°C.

(3) Peak current for approximate 30% roll off at 20°C.

(4) DCR limits @ 20°C.

(5) Applied Volt-Time product (V-µS) across the inductor. This value represent the

applied V-µS at 100KHz necessary to generate a core loss equal to 10% of the

total losses for 40°C temperature rise.
