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).
B = Less than full reel
In tape, 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
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
