(1) Test Parameters: 100KHz, 0.100Vrms, 0.0Adc.
(4) DCR limits @ 20°C.
(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.
De-rating is necessary for AC currents.
(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.
De-rating of the Irms is required to prevent excessive temperature rise.
(3) Peak current for approximately 30% rolloff at 20°C.
