(2) Irms: DC current for an approximate T of 40C 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 125C under worst case operating conditions verified in the end application.
