Values 20C 1. Open Circuit Inductance Test Parameters: 300kHz, 0.250 Vrms, 0.0 Adc 5. Applied Volt-Time product (V-s) across the inductor. This value represents the applied V-s at 2. DC current for an approximate temperature change of 40C without core loss. Derating is necessary 300KHz neccessary to generate a core loss equal to 10% of the total losses for 40C temperature rise. 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 125C under worst case operating conditions verified in the end application. 3. Peak current for approximately 30% rolloff.
