DO5022H Series High Current
Surface Mount Power Inductors

NOTE: We now offer an improved version of this series: DO5010H. It is electrically equivalent, has a smaller footprint and comes in more inductance values. Existing customers will continue to be supported.
  • Very high current ratings – up to 15 Arms, 30 A saturating current!
  • Exceptionally low DC resistance thanks to the use of heavier gauge wire
  • Flat top and self-leaded design for reliable surface mounting
  • Robust temperature deflection prevents damage during solder reflow
  • RoHS-compliant. 260°C compatible. Tin-silver over copper terminations.

1 When ordering, please specify packaging code: e.g. DO5022H-153MLD
  Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel
In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
2 Inductance tested at 100 kHz, 0.1 Vrms
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using Agilent/HP 8753D network analyzer. Details
5 Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
6 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.
7 Operating temperature range −40°C to +85°C.
8 Electrical specifications at 25°C
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
