SMC Technical Specification

The SMC (Sub-Miniature-C) connector is similar in design to the SMB. The inner contact and overlapping dielectric insulator structures are identical, but the SMC utilises a threaded coupling interface rather than a snap-on interface. Tighter control of the contact and insulator locations, because of the threaded coupling, allow the SMC to operate up to frequencies of 10 GHz in 50 ohm impedance designs. The threaded connection makes the SMC a good choice for applications where the need for small size and performance in high vibration environments are concerns. SMC connectors are used primarily in applications for microwave telephony and other non-military telecommunication requirements. SMC PLUG SMC JACK Products are manufactured in accordance with MIL-C-39012. The above specifications are typical, although some variations may occur within the range.
