Notes:
(1) Open Circuit Inductance Test Parameters: 100 kHz, .25Vrms, 0.0Adc.
(2) DCR limits 20°C.
(3) 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.
(4) Peak current for approximately 30% rolloff at 20°C.
(5) Applied Volt-Time product (V-µS) across the inductor. This value
represents the applied V-µS at 300KHz necessary to generate a core
loss equal to 10% of the total losses for 40°C temperature rise.
