The 75 Ohm impedance and 12 GHz maximum frequency target it squarely at broadcast video, high-definition serial digital interface (HD-SDI), and CCTV applications where signal integrity at high data rates matters. ## What the Key Specs Mean for the Install The 75 Ohm impedance is not a typo — this is a video-grade BNC, not the 50 Ohm version common in data comms. Mating it with a 50 Ohm cable or connector will create an impedance mismatch that degrades return loss above a few hundred megahertz. The 12 GHz bandwidth is well beyond the 3 GHz ceiling of most HD-SDI links, so this connector won't be the bottleneck in a 12G-SDI path. The kit includes the ferrule, so you don't need to source it separately. The specified Belden 4694R is a precision 75 Ohm broadcast coax. If your cable is a different 75 Ohm coax with similar dielectric diameter, the crimp die and strip dimensions will need to be verified against the manufacturer's tooling guide. ## Build and Environment Brass body with nickel finish, PTFE dielectric, and a silver housing. The bayonet lock gives a positive quick-connect that holds under moderate vibration — not rated for continuous flex, but fine for a patch panel or camera connection that gets cycled occasionally.","metaTitle":"031-70547-12G BNC Jack, 75 Ohm, Crimp, 12 GHz","metaDescription":"031-70547-12G BNC jack, 75 Ohm, crimp termination, 12 GHz max, 500 mating cycles.
