UNI-PAC™ Surface Mount Inductors
GENERAL
The UNI-PAC™ product family consists of surface
mount inductors designed for use in applications requiring
low inductance and high current in a miniature package.
These products can be used in DC/DC converters and as
signal conditioning or filter inductors. Available standard
inductance values range from 0.47 to 100 µH. RMS
current values range from 19.2 to 0.47 Amperes.
Because of their miniature size and rugged
construction, the UNI-PAC family is ideally suited for
products requiring higher power per millimeter of PCB
space. Such applications include notebook computers,
pagers, and a variety of battery powered equipment. Their
versatility extends to use in DC/DC converters on all
board level products from personal computers to
industrial-level VME products.
The UNI-PAC product family is engineered for high
volume production using automated surface mount
technology. Tape-and-reel packaging accommodates
reliable pick-and-place manufacturing, and their
construction permits normal exposure to infrared reflow
soldering to +240°C.
In addition to the standard inductance values shown,
modified UNI-PAC inductors are available to meet your
exact high volume requirements.
A protective case has been added to reduce core
breakage, currently available in sizes 1 and 2.
