: 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.
