SMB/SMC Conectors

_____________________________

 

SMB connectors are sub miniature RF connectors with quick disconnect snap-on couplings which offer broadband performance from 0 to 4 GHz at 50 ohm impedance. 

SMC types have a 10-32 UNF threaded coupling. These screw on designs operate reliably to 10 Ghz at a 50 ohm impedance. 

SBC and SMC connectors are included in the smallest series available for RF coaxial applications. The small size allows interconnects on the most miniature of devices, devices with multiple posts where high density is required, where lighter weight end products are essential, and where it is necessary, to fit miniature, and sub miniature cables.
