Notes:
(1) Open Circuit Inductance Test Parameters: 100 kHz, .25Vrms, 0.0Adc.
(2) DCR limits 20°C.
(3) RMS current for an approximate
ΔT
of 40°C without core loss. It is rec-
ommended that the temperature of the part not exceed 125°C.
(4) Peak current for approximately 30% rolloff at 20°C.
(5) Applied Volt-Time product (V-μS) across the inductor. This value repre-
sents the applied V-μS at 300KHz necessary to generate a core loss
equal to 10% of the total losses for 40°C temperature rise.
