Shielded Power Inductors – DS5022P
The DS5022 Series of magnetically shielded power
inductors is designed for the higher current requirements 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 recommend the MSS1278 as an alternative. The MSS1278
series is more cost effective, features a smaller footprint,
lower DCR and better current handling.

1. When ordering, please specify termination and packaging code:
DS5022P-105MLD
Termination:L=RoHS compliant electroplated gold (<50 µin) 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).
Packaging:D= 13″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts per full reel).
B=Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge),
use code letter D instead.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DC current at which the inductance drops from its value without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
