1 Open Circuit Inductance Test Parameters 100kHz, 0.1V, 0.0Adc. 2 Irms DC current for an approximate 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 Isat Amperes peak for 30% maximum rolloff
