: DC current for an approximate temperature rise of 40°C without core loss. Derating is
necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of
other heat generating components will affect the temperature rise. It is recommended the part
temperature not exceed 125°C under worst case operating conditions verified in the end
application.
