The rated current as listed is either the saturation current or the heating current depending 4. In high volt*time applications, additional heating in the component can occur due to on which value is lower. core losses in the inductor which may neccessitate derating the current in order to limit 2. The saturation current is the typical current which causes the inductance to drop by 20% at the temperature rise of the component. To determine the approximate total losses (or the stated ambient temperatures (25C and 100C). This current is determined by placing temperature rise) for a given application, the coreloss and temperature rise formula the component in the specified ambient environment and applying a s hort duration can be used: pulse current (to eliminate self-heating effects) to the component. B (Gauss) = K2 * I 1.63 * 2.62 B 3. The heating current is the DC current which causes the part temperature to increase by Core Loss (W) = 1.5E-13 * (Freq kHz) approximately 40C. 5. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
