SMC 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.[1] They use a #10-32 UNF threaded interface (screw type). They offer electrical performance from DC to 4 GHz. Some extended performance versions are rated to 10 GHz The normally free part (a.k.a. plug) of a SMC connector have a socket for the center contact so are Female.The normally fixed part (a.k.a. jack) SMC connectors have a pin for the center contact so are Male. This is the reverse of most RF connectors. SMC jack connectors have an external thread while SMC plug connectors have the mating hex nut. The contact dimensons are identical to the snap-fit SMB. 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 small footprint is important.

For SMC surface mount diode package, see DO-214.

The term Subvis connector appears to be European usage; the connectors appear to be electrically and mechanically equivalent to SMC.[2]
