: DC current for an approximate temperature rise 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.
