Manufacturer of Components

A Leading Manufacturer of Ceramic EMI/RFI Electronic Components

TUSONIX, Inc., a world leader in the design and manufacture of Ceramic EMI/RFI Components, was formed in 1981 by the acquisition of a long established component manufacturer. Once acquired, the management team implemented its own unique vision to further develop the established operations and create a Tradition of Excellence, Quality and Innovation. These efforts have placed TUSONIX in the forefront of industry developments.

Company operations have been manufacturing ceramic components in the Southwest United States since 1969.  Today, TUSONIX draws upon this tradition of manufacturing experience and an accumulated base of ceramic dielectric technology to provide an ever expanding line of EMI/RFI products and ceramic fixed and variable capacitors, which not only set the industry standard but lead the way in the development of tomorrow's EMI technology.

Headquartered in Tucson, Arizona, TUSONIX utilizes over 120,000 square feet (11,150 square meters) of manufacturing and administrative facilities, to provide cost effective EMI solutions to OEMs on six continents.  It is this commitment to global competitiveness that has enabled TUSONIX to develop an attractive cost structure while providing high quality products which help manufacturers meet EMC compliance issues from every regulating body worldwide.
