Product details

75 Ohm MCX Plug for RG-179 — Field-Termination Fit

The Samtec MCX7-P-C-H-ST-CA3 is a 75 Ohm MCX plug from the TRUE75™ MCX7 series, built for RG-179 cable. Rated to 6 GHz and 170 V, it handles modern HD video and high-rate data signals without breaking a sweat.

Cable Prep and Termination Sequence

This plug terminates to RG-179 coax with a solder centre contact and a crimp shield termination. The centre pin is soldered to the signal conductor; the braid is crimped over the body for a solid 360° shield bond. The PTFE dielectric material in the connector matches the RG-179 dielectric, keeping the 75 Ohm impedance continuous through the junction. Free-hanging mount means it terminates the cable end directly — no PCB footprint needed.

Snap-On Coupling and Operating Range

The snap-on fastening is the standard MCX interface — quick to mate and unmate, but not threaded, so it's best in applications where vibration is controlled (rack equipment, test leads, indoor runs).

Frequently asked questions
