The heating current is the DC current, which causes the temperature of the part to increase by 1. Temperature of the component (ambient plus approximately 40C. This current is determined by extendtemperature rise) must be within specified operating ing the terminals of the component with 30mm length 28 temperature range. gauge buss wires and applying the current to the device for 30 minutes. The temperature is measured by placing 2. The rated current as listed is either the saturation current the thermocouple between the winding and the shield. or the heating current depending on which value is lower. 3. The saturation current is the current which causes 5. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor the inductance to drop to 75% of its initial inductance at which may necessitate derating the current in order to limit zero bias. This current is determined by placing the the temperature rise of the component. In order to detercomponent at room ambient (25C), and applying a short mine the approximate total loss (or temperature rise) for a duration pulse current (to eliminate self-heating effects) to given application, both copper losses and core losses the component. should be taken into account.
