Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
: DC current for an approximate ΔT 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.
