DO5022H Series

High Current Surface Mount Power Inductors

RoHS compliant
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.

Notes
  1. When ordering, please specify packaging code: e.g. DO5022H-153MLD
  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.

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = 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.
