SMT Power Inductors – DO5022 Series
This series of surface mount power inductors is designed
for the higher current requirements of notebook computers
and other portable and handheld devices.
A 1 µH inductor is rated at 8.6 Arms with a saturation current
of 20 Amps. Exceptionally low dc resistance (as low as
0.009 Ohm) keeps power losses to a minimum.
The DO5022 Series was designed specifically for surface
mounting. It has a flat top for reliable pick-and place
operations and features robust temperature deflection.
In addition to the standard versions shown here, custom
inductors are available to meet your exact requirements.
