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°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°C.
This current is determined by extending the terminals of the
component with 30mm length 28 gauge buss wires and
applying the current to the device for 30 minutes. The tem-
perature is measured by placing the thermocouple between
the winding and the shield.
4. In high volt*time applications, additional 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 deter-
mine the approximate total loss (or temperature rise) for a
given application, both copper losses and core losses
should be taken into account.
Estimated Temperature Rise:
Trise = [Total loss (mW) / 6.288]
