the component inductance drops by the indicated
percentage (typical) at an ambient temperature of
25°C. This current is determined by placing the
component in the specified ambient environment and
applying a short duration pulse current (to eliminate
self-heating effects) to the component.
to raise the component temperature by the indicated
delta (approximately). The heating current is
determined by mounting the component on a
typical PCB and applying current for 30 minutes. The
temperature is measured by placing the thermocouple
on top of the unit under test.

Estimated Temperature Rise:
Trise = [Total loss (mW) / K0]
Total loss = Copper loss + Core loss (mW)
Copper loss = I
Irms = [I
Core loss = K1 x f (kHz)
Bac (peak to peak flux density) = K2 x ΔI (Ga)
K2 is a core size and winding dependant value and
where f varies between 25kHz and 1MHz, and Bac is
less than 2500 Gauss.

K0 & K1 are platform and material dependant constants
and are given in the table below for each platform.
tional heating in the component can occur due to core
losses in the inductor which may necessitate derating
the current in order to limit the temperature rise of the
component. In order to determine the approximate total
loss (or temperature rise) for a given application, both
copper losses and core losses should be taken into
account.
