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
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

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
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.
