'''SMC''' (''SubMiniature version C'') connectors are coaxial [[RF connector]]s developed in the 1960s. The interface specifications for the SMC and many other connectors are referenced in MIL-STD-348.<ref name="MIL-STD-348">{{cite book |title=RADIO FREQUENCY CONNECTOR INTERFACES FOR MIL-DTL-3643, MIL-DTL-3650, MIL-DTL-3655, MIL-DTL-25516, MIL-PRF-31031, MIL-PRF-39012, MIL-PRF-49142, MIL-PRF-55339, MIL-DTL-83517 |date=2017-01-22 |publisher=US DOD |edition=B with change 3 |url=http://quicksearch.dla.mil/qsDocDetails.aspx?ident_number=35726}}</ref> They use a [[Unified Thread Standard#Designation|#10-32]] [[Unified fine thread|UNF]] threaded interface (a screw type). They offer electrical performance from [[direct current]] (DC) to 4&nbsp;GHz. Some extended performance versions are rated to 10 GHz. The normally free part (a.k.a. plug) of a SMC connector that has a socket for the centre contact are the female connectors. The normally fixed part (a.k.a. jack) SMC connectors that has a pin for the centre contact are the male connectors. 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 dimensions 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.

The term '''Subvis connector''' appears to be a European usage; the connectors appear to be electrically and mechanically equivalent to SMC.<ref>[http://www.cdint.com/catalog/model/CC-SC Discussion of SMC/Subvis equivalence]</ref>
