: 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.
