Notes from Table
1. The rated current as listed is either the saturation current
or the heating current depending on which value is lower.
2. The saturation current is the current which causes the
inductance to drop to 65% (or 75%) of its nominal induc-
tance at zero bias. This current is determined by placing
the component at room ambient (25擄C), and applying a
short duration pulse current (to eliminate self-heating
effects) to the component.
3. The heating current is the dc current, which causes the
temperature of the part to increase by not more than 40擄C.
This current is determined by extending the terminals of the

Total loss = Copper loss + Core loss (mW)
4. In high volt*time applications, additional heating in the
