DS5022P Series

Shielded Surface Mount Power Inductors

We 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.

DS5022P MSS1278

This series was always RoHS compliant; only the part numbers changed. Added characters indicate tolerance, RoHS compliance, and packaging. View old data sheet.
Magnetically shielded
Designed for higher load currents – up to 18 A saturating current, 6.5 A rms
Very low DCR keeps power losses to a minimum
Robust temperature deflection prevents damage during solder reflow
End terminations for sound solder fillets and easy inspection
RoHS-compliant 260°C compatible. Electroplated gold (<50 µin) over nickel over phos bronze terminations.
COTS Plus tin-silver-copper and tin-lead terminations available

Notes

When ordering, please specify termination and packaging codes: e.g. DS5022P-105MLD
Inductance tested at 100 kHz, 0.1 Vrms.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

L = Gold over nickel over phos-bronze.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

D = 13" reel, machine-ready
EIA-481 embossed plastic tape (250 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.
