Notes: (1) The rated current (Irated) is the approximate current at which the inductance will be decreased by 20% typical from its initial (zero DC) value.
(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.
