NOTES: 1. The rated current as listed is either the saturation current or the heating current depending on which value is lower. 2. The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient temperatures (25C and 100C). This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 3. The heating current is the DC current which causes the part temperature to increase by approximately 40C.
4. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor which may neccessitate derating the current in order to limit the temperature rise of the component. To determine the approximate total losses (or temperature rise) for a given application, the coreloss and temperature rise curves can be used. 5. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
