SMTPowerInductors-DO5022H Series
We now offer an improved version of
this series: DO5010H.
It is electrically equivalent, has a smaller footprint and
comes 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 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.

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.
