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).
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 0.1 Vrms, 100 kHz, 0 Adc.
3. DC current at which the inductance drops 10% (typ) from its value
without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5.
Ambient temperature range:
–40°C to +85°C with
Irms
current
+85°C to +125°C with derated current
6.
Storage temperature range:
Component: –40°C to +125°C
Packaging: –40°C to +80°C
7.
Resistance to soldering heat:
Three reflows at >217°C for 90 seconds
(+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room
temperature between.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
