This family of inductors was designed for high current,

low-voltage DC-DC converter applications, especially the

latest 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 low

DC resistance thanks to the use of heavier gauge wire. The

DO5022H Series has been optimized for reliable surface

mounting with a large flat top and self-leaded design. In

addition to the standard parts shown, custom values are

available.

1. When ordering, please specify packaging code:

DO5022H-153ML

D

Packaging: D =13

″ machine-ready reel. EIA-481 embossed

plastic tape.

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.

2. Inductance tested at 100 kHz, 0.1 Vrms.

3. SRF measured using Agilent/HP8753D network analyzer.

4. DC current at which the inductance drops 10% (typ) from its

value without current.

5. Average current for a 40°C rise above 25°C ambient.

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.

We now offer an improved version of

It is electrically equivalent, has a smaller footprint and

comes in more inductance values. We will, however,

continue to produce the DO5022H indefinitely.
