Inductor Derating Guide Lines based on Temperature

How to Derate a Inductors based on Temperature, and load.

**Inductor Temperature Correction**
	Current Derating Factor @ Application Ambient Temperature
	Military		Commercial
Load Type	0^oC to 85^oC	Above 85^oC	0^oC to 85^oC	Above 85^oC
Resistive	75% of rated Resistive load	60% of rated Resistive load	75% of rated Resistive load	60% of rated Resistive load
Inductive / Motor	75% of rated Inductive load	60% of rated Inductive load	40% of rated Resistive load	30% of rated Resistive load
Capacitive / Lamp	75% of rated Capacitive load	60% of rated Capacitive load	25% of rated Resistive load	20% of rated Resistive load

Inductors are also derated by reducing the maximum operating temperature based on the insulation class and reducing the operating voltage. Listing of Inductor manufacturers
