Mini-UHF RF Connectors
RF Connectors > Mini-UHF RF Connectors
Description
Introduced in the 1970’s, Mini-UHF is a miniature version of the UHF connectors that were invented in the 1930’s for use in the radio industry. Mini-UHF connectors are designed for use as coaxial interconnection in cell phones, automotive systems, and similar applications where size, weight, and cost factors are critical.
Mini-UHF connectors terminate to RG-58, RG-58A, RG-58B, RG-58C, and Belden 9258 cables. Crimp-type cable plugs and jacks are available as well as panel and printed circuit board receptacles.
