(1) DC resistance is measured at 25C (2) The saturation current (Isat) is the current at which the inductance will be decreased by 20% from its initial (zero DC) value. (3) The heating current is the DC current, which causes the component temperature to increase by approximately 50C. This current is determined by soldering the component on a typical application PCB, and then apply the current to the device for 30 minutes. (4) Core Loss approximation is based on published core data: Core Loss (Pfe) = K1 * (f)1.338 * (K2I)2.2546 Where: core loss in watt f = frequency in kHz K1 and K2 = core loss factor I = delta I across the component in Amp. K2I = one half of the peak to peak flux density across the component in Gauss
