It is part of the 91922 series, a subminiature snap-on coaxial interface that mates with standard MCX plugs. The 75 Ohm impedance targets video, broadband, and CATV signal paths — not the 50 Ohm RF chain common in telecom or test equipment. The gold-plated brass body and beryllium copper center contact with gold plating deliver 500 mating cycles, a solid reconnect life for a snap-on connector. ## Impedance and Frequency — What 75 Ohm Means for the Signal Path This is not a 50 Ohm MCX — plugging a 50 Ohm cable into this receptacle creates an impedance mismatch that degrades return loss and increases VSWR. The connector is rated to 1 GHz maximum frequency with 0.1 dB insertion loss, which is consistent with a quality 75 Ohm video/data path. For 50 Ohm applications, look for a 50 Ohm variant in the same 91922 series. ## SMT Termination and Assembly Fit Surface-mount termination means this receptacle is intended for automated pick-and-place reflow assembly, not hand-soldering. The snap-on fastening provides quick, tool-less mating with a standard MCX plug — the audible click confirms full engagement. The gold body finish and gold center contact plating resist corrosion in humid or mildly corrosive environments. ## Materials and Operating Range The brass body with gold finish and beryllium copper center contact with gold plating give this connector a robust mechanical and electrical life.","metaTitle":"Amphenol 919-226J-71P MCX Receptacle, 75 Ohm, SMT, 1 GHz","metaDescription":"Amphenol 919-226J-71P MCX receptacle, female socket, 75 Ohm impedance, SMT mount, gold body, rated to 1 GHz.
