SMT Power Inductors
Shielded Drum Core - PA4338.XXXNLT Series
P804.B (11/17)
Height: 4.2mm Max
Footprint: 8.3mm x 8.3mm Max
Current Rating: up to 6.3A
Inductance Range: 0.82uH to 330uH
Shielded magnetic circuit reduces leakage ux, Fe base metal core
enables high saturation and metalized core termination results in
excellent shock resistance.

1. Actual temperature of the component during system operation (ambient plus temperature
rise) must be within the standard operating range.
2. The saturation current is the current at which the initial inductance drops approximately
30% at the stated ambient temperature. This current is determined by placing the compoent
in the specified ambient environment and applying a short duration pulse current (to
Notes:
eliminate self-heating eect) to the component.
3. The Rated Current is the DC current required to raise the component temperature by
40 °C maximum. Take note that the component’s performance varies depending on the
system condition. It is suggested that the component be tested at the system level, to
verify the temperature rise of the component during system operation.
