1) Test Parameters: 300kHz, 0.25 Vrms

2) DC current for approximately

∆T of 40°C without core loss

De-rating is necessary for AC currents. PCB layout, trace thickness and width,

air flow and proximity of other heat generating components will affect temperature

rise. It is recommended that the temperature of the part not exceed 125°C under

worst case conditions verified in the end application.

3) Peak current for approximately 30% rolloff (@20°C)

4) 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 a 40°C temperature rise.
