SMTPowerInductors-DO5022HSeries
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,
continuetoproducetheDO5022Hindefinitely.
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.
