SMTPowerInductors-DO5022HC Series
We now offer an improved version of
this series: DO5010HC.
It is electrically equivalent, has a smaller footprint and
comes in more inductance values. We will, however,
continue to produce the DO5022HC 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 DO5022HC 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.

Recommended
Land Pattern
1. Part number on reel label may have a B suffix to indicate that the
reel is not machine ready.
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.
See Qualification Standards section for environmental and test data.
