(1) Open Circuit Inductance T est 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-uS) across the inductor at 100kHz necessary to
generate a core loss equal to 10% of the total losses for 40°C temperature rise.
