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 current which causes the inductance to drop to 65% (or 75%) of its nominal inductance at zero bias. This current is determined by placing the component at room ambient (25°C), 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 temperature of the part to increase by not more than 40°C. This current is determined by extending the terminals of the Estimated Temperature Rise: component with 30mm length 28 gauge buss wires and applying the current to the device for 30 minutes. The tem.833 o (C) perature is measured by placing the thermocouple between Trise = [Total loss (mW) / 4.728] the winding and the shield. Total loss = Copper loss + Core loss (mW) 4. In high volt*time applications, additional heating in the Copper loss = Irms2 x DCR (Typical) (mW) component can occur due to core losses in the inductor which may necessitate derating the current in order to limit Irms = [IDC2 + ∆I2/12]1/2 (A) the temperature rise of the component. In order to deterCore loss = 2.25 x 10-7 x f (kHz)1.1 x (K x ∆I)2.15 (mW), mine the approximate total loss (or temperature rise) for a given application, both copper losses and core losses where f varies between 25 kHz and 300 kHZ, and B less should be taken into account. than 2000 Gauss.
