SMT Power Inductors - DO3316HC Series
The DO3316HC series has been specially designed for
high current, low voltage DC-DC converter applications.
This simple, rugged design provides current ratings nor-
mally available only in much larger packages — up to
17 Arms for a 0.12 µH part! With its tinned self-leaded
construction, the DO3316HC achieves very low DCR
values and excellent solderability. In addition to the
standard parts shown, custom values are also available.
TheDO3316HCseriesincludesfeaturessuchastapeand
reel packaging and a flat top for pick-and-place handling
that are standard in all Coilcraft SMT power products.
