UHF / Mini UHF Connectors




 
Description :
Bestnet UHF/MINI-UHF connectors are popular and economical, used when impedance mating is not required. General purpose units are designed to operate satisfactorily up to 500 MHz. They have a peak voltage rating of 500 volts.
Mini-UHF is a miniature version of the UHF connectors that were developed for use in the radio industry. Mini-UHF connectors are designed for use as coaxial interconnection in cell phones, automotive systems, and similar applications were size, weight and cost factors are criticall Mini-UHF connectors terminate to RG-58, RG-58A, RG-58B, RG-58C, and Belden 9258 cables. Crimp-type cable plugs and jacts are available as well as panel and printed circuit board receptacles.
