GENERAL
UNI-PACs are surface mount inductors designed for use in
applications requiring low inductance and high current in a miniature
package. They can be used in DC/DC converters and as signal
conditioning or filter inductors. Available standard inductance values
range from 0.47 to 330.0 µH. RMS current values range from 19.2 to
0.76 Amperes.
Because of their miniature size and rugged construction, UNI-PACs
are 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.
UNI-PACs are engineered for high volume production using
automated surface mount technology. Their 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, custom
inductors are available to meet your exact high volume requirements.
