SMT POWER INDUCTORS
Shielded Drum Core - PL94XX Series
Notes from Tables
1. Temperature of the component (ambient plus
temperature rise) must be within specified operating
temperature range.
2. The rated current as listed is either the saturation current
or the heating current depending on which value is lower.
3. The saturation current is the current which causes
the inductance to drop to 75% of its initial inductance 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.
4. The heating current is the DC current, which
causes the temperature of the part to increase by
approximately 40°C. This current is determined by extend-
ing the terminals of the component with 30mm length 28
gauge buss wires and applying the current to the device
for 30 minutes. The temperature is measured by placing
the thermocouple between the winding and the shield.
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 deter-
mine the approximate total loss (or temperature rise) for a
given application, both copper losses and core losses
should be taken into account.
