Notes: (1) DC resistance is measured at 25°C.
(2) The rated current (Irated) 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 40°C. This current is determined
by soldering the component on a typical application PCB, and then applying the device for 30 minutes.
(4) Core Loss approximation is based on published core data:
Core Loss = K1 * (f)^1.77 * (K2ΔI)^2.21
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 = one half of the peak to peak flux density across the component in Gauss
