SMC Coaxial Connector

SMC (SubMiniature version C) connectors are coaxial RF connectors developed in the 1960s. The interface specifications for the SMC and many other connectors are referenced in MIL-STD-348. They use a #10-32 UNF threaded interface (screw type). They offer electrical performance from DC to 10 GHz. Female / Jack SMC connectors have a socket for the center contact, and male / Plug SMC connectors have a pin for the center contact.

SMC jack connectors have an external thread while SMC plug connectors have the mating hex nut. Available in 50-Ohm and 75-Ohm characteristic impedance, they provide an interconnect means for small form factor coaxial cables (e.g. 50-Ohm RG-174, 75-Ohm RG-179) and printed circuit boards where a small footprint is important.
