1) Open Circuit Inductance Test Parameters: 300kHz, 0.250 Vrms, 0.0 Adc
2) DC current for an approximate temperature change of 40°C without core loss.
Derating is necessary for AC currents.
PCB layout, trace thickness and width, air-flow and proximity of other heat
generating components will affect the temperature rise.
It is recommended that the temperature of the part not exceed 125°C under

3) Peak current for approximately 30% roll-off
4) Values @ 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.
