Rated to 4.5 GHz and 170 V, this connector is built for video, broadband, and other 75 Ohm RF signal paths where a compact, snap-lock interface is needed. ## 75 Ohm Impedance — Not Your Standard 50 Ohm MCX Standard MCX connectors are 50 Ohm; this TRUE75™ variant keeps the same snap-on interface but matches 75 Ohm cable and system impedance — critical for video distribution, CCTV, and broadband data where a 50 Ohm stub would create a reflection. The 4.5 GHz max frequency is a practical ceiling for this impedance; the straight-mate sibling MCX7-P-C-H-ST-CA3 is rated to 6 GHz, so the right-angle bend in the RA-CA3 introduces a small additional discontinuity that limits the top end. For runs up to 4.5 GHz the right-angle body saves board-edge space without a separate adapter. ## Termination Sequence — Solder Centre, Crimp Braid Termination is a two-step process: solder the centre contact to the RG-179 centre conductor, then crimp the shield termination over the braid. The PTFE dielectric holds the centre pin concentric through the solder cycle.","metaTitle":"Samtec MCX7-P-C-H-RA-CA3, MCX Plug, 75 Ohm, 4.5 GHz","metaDescription":"Samtec TRUE75™ MCX7 right-angle plug for RG-179, 75 Ohm impedance, 4.5 GHz max frequency, gold body, snap-on mate.
