SMT Power Inductors – DO1608 Series
The DO1608 Series has a footprint of only 0.26″ × 0.175″
(6,6 mm × 4,5 mm). Their high energy storage and very
low resistance make them the ideal inductors for DC-DC
conversion in notebook computers, PDAs, step-up or
step-down converters, flash memory programmers, etc.
For reliable surface mounting, we’ve designed the DO
Series with a flat top and robust temperature deflection to
prevent damage during solder reflow.
In addition to the standard versions shown here, custom
inductors are available to meet your exact requirements.
