PCB layout, trace thickness and width, air-flow, and proximity of other heat HCP0805 = Product code and size generating components will affect the temperature rise. It is recommended that the temperature XXX = Inductance value in uH, R = decimal point, of the part not exceed 125C under worst case operating conditions verified in the end application.
