SMT POWER INDUCTORS
Shielded Drum Core - PL95XX Series
Notes from Tables
1. Temperature of the component (ambient plus temperature rise) must be within specified operating 4. The heating current is the DC current, which causes the temperature of the part to increase by
temperature range.
approximately 40°C. This current is determined by extending the terminals of the component with
2. The rated current as listed is either the saturation current or the heating current depending on which
value is lower.
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.
3. The saturation current is the current which causes the inductance to drop to 75% of its initial 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.
5. 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 determine the approximate total loss (or temperature rise) for a given
application, both copper losses and core losses should be taken into account.
