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 HCP0704 = Product code and size +125 C under worst case operating conditions verified in the end application. xxx= Inductance value in H, R = decimal point.
