(1) DC resistance is measured at 25擄C.
(2) The rated current (I
rated
) 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擄C. This current is determined
by soldering the component on a typical application PCB, and then apply the device for 30 minutes.
(4) Core Loss approximation is based on published core data:
Core Loss = K1 * (f)
1.77
* (K2鈭咺)
2.21
Where: core loss in watt
f = switching frequency in kHz
K1 and K2 = core loss factor
鈭咺
= delta I across the component in Amp.
K2鈭咺 = one half of the peak to peak flux density across the component in Gauss
