Document 188-1 Shielded Power Inductors DS5022P 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. Coilcraft will continue to manufacture and support the DS5022P indefinitely, however for new designs, we rec - ommend the MSS1278 as an alternative. The MSS1278 series is more cost effective, features a smaller footprint, lower DCR and better current handling. DCR SRF 1.
