Sub Miniature C Connector
SMC connectors use a #10-32 UNF threaded interface (screw type). They offer electrical performance from DC to 10 GHz. Female SMC connectors have a socket for the center contact, and male 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 and printed circuit boards where small footprint is important.
