CC-SC is a 50 ohm male SMC plug. The hex-head design fits a 6 mm wrench. The center pin solders onto the core wire, providing a low-noise electrical connection. The outer crimp ferrule is sized for the shield and jacket of an RG174, RG316, or similar-size coaxial cable -- the maximum cable size which will fit this connector is about 3mm diameter. Cables with a diameter smaller than 2mm will need heatshrink added around the jacket to add to their diameter and make a secure mechanical connection when crimped.

SMC connectors, like the 10-32 Microdot family, use 10-32 machine screw threads. They differ from Microdot connectors in their dielectric configuration, and when mated provide better airgap closure for protection against leakage and high-voltage breakdown.

SMC connectors are usable up to around 4 GHz, and due to their threaded mating are a better alternative than SMB connectors in high-vibration environments.

SMC stands for "SubMiniature version C"; this family of connectors was originally designed in the 1960's, and is described in MIL-C-39012/73/78.

While we have been unable to locate relevant standards documents, we've received feedback from multiple customers that indicates that SMC connectors are mechanically and electrically compatible with "Subvis" connectors, and may in fact be the same device. As far as we can tell so far, the term "Subvis" appears to be European or Australian usage, though we've been unable to locate the origin. If you have additional information that can shed light on this, please feel free to contact us or post a review.

This connector has a characteristic impedance of 50 ohms, and needs to be mated with 50 ohm coaxial cable in order to prevent signal loss, noise, and/or transmitter damage due to signal reflections at the point of mismatch. 50 ohm coax cable, connectors, and adapters are commonly used in GPS and wifi (802.11 wireless LAN) antennas, ham transceivers, and other radio frequency (RF) analog and digital signaling, microwave, radar, hi-fidelity professional audio, non-destructive testing (NDT), oil and petroleum production, ultrasonic transducers, accelerometers, strain gauges, and some professional video applications.
