: 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.
