SMT Power Inductors – DS5022P Series
The DS5022 Series of magnetically shielded power
inductors is designed for the higher current require-
ments of portable computers, video recorders and other
DC-DC conversion applications.
They feature saturation current ratings as high as
18 Amps and rms current ratings up to 6.5 Amps. Low
DC resistance (as low as 0.040 Ohms) keeps power
losses to a minimum.
For new designs, consider the MSS1278 as an alter-
native to this series. The MSS1278 series is more cost
effective, features a smaller footprint, lower DCR and
better current handling. We will continue to manufacture
and support the DS5022P indefinitely.

1. When ordering, please specify termination and packaging codes:
DS5022P-105MLD
Termination: L = RoHS compliant gold over nickel over phos bronze.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
