SMT Power Inductors - DO5022H Series
We now offer an improved version ofthis series: DO5010H.
It is electrically equivalent, has a smaller footprint andcomes in more inductance values. We will, however,continue to produce the DO5022H indefinitely.
This family of inductors was designed for high current,low­‑voltage DC-DC converter applications, especially thelatest generation of 3.3 V microprocessors. Current ratings up
to 15 A rms and saturation currents up to 30 A are available.
These parts are only 8,0 mm high and have exceptionally lowDC resistance thanks to the use of heavier gauge wire. TheDO5022H Series has been optimized for reliable surface
mounting with a large flat top and self-leaded design. Inaddition to the standard parts shown, custom values areavailable.

1Packaging: 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 = Less than full reel. In an effort to simplify ourpart numbering system, Coilcraft is eliminating
the need for multiple packaging codes. Whenordering, simply change the last letter of yourpart number from B to D..
2. Inductance tested at 100 kHz, 0.1 Vrms.
3. SRF measured using Agilent/HP8753D network analyzer.
4. DC current at 25°C that causes an inductance drop of 10% (typ)from its value without current.
5. 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.
6. Operating temperature range –40°C to +85°C.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
