Notes:
(1) DC Resistance measured at 25°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 50°C. 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:
1.338
2.2546
Core Loss (Pfe) = K1 * (f)
* (K2∆I)
Where:
core loss = in watt
f = frequency in kHz
K1 and K2 = core loss factor
∆I
= delta I across the component in Amp.
K2∆I = one half of the peak to peak flux density across the component in Gauss
