(2) The heating current is the DC current which causes the component tempreture to increase by approximately 40°C. (3) Isat is the saturated current at which inductance will be decreased by 30% from its initial (zero DC) value. (4) Core loss approximation is based on published core data. Core Loss = K1* (f)1.46 * (K2ΔI)2.0 Where: Core loss = in watt. f = switching frequency in kHz. K1 and K2 = core loss factor. ΔI = delta I across the component in Amp. K2ΔI = peak to peak flux density across the component in Gauss.
