The 75 Ohm impedance matches broadcast video, CCTV, and HD-SDI infrastructure—not the 50 Ohm world of RF test equipment. ## Cable-Specific Termination Kit The bulk package includes three pieces: the connector body, a center contact, and a ferrule. The center contact is crimped onto the center conductor of Canare L-5.5CUHD, and the ferrule crimps over the braid. This is not a universal BNC—using a different cable changes the impedance and the crimp dimensions, so stick with the specified cable group for a proper 75 Ohm match.","metaTitle":"Amphenol RF 031-70553-12G BNC Jack, 75 Ohm, 12 GHz, Crimp","metaDescription":"Amphenol RF 031-70553-12G BNC jack, female socket, 75 Ohm impedance, 12 GHz max frequency.
