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 worst case operating conditions verified in the end application.

3. Peak current for approximately 30% rolloff.

4. Values @ 20°C

5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at

300KHz neccessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise.
