The rated current as listed is either the saturation current or the heating current depending on which value is lower. duration pulse current (to eliminate self-heating effects) to the component. 2. The saturation current is the current which causes the inductance to drop by 10% at the stated ambient temperature of 25°C. This current is determined by placing the component in the specified ambient environment and applying a short 3. The heating current is the dc current which causes the temperature of the part to increase by approximately 40°C. This current is determined by mounting the component on a PCB with .25" wide, 3 oz. equivalent copper traces, and applying the current to the device for 30 minutes.
