It carries a gold-plated brass centre contact rated for 500 mating cycles, with a nickel-plated zinc die-cast body in a black and silver housing. The connector style is jack, female socket, single port, and it includes a board guide and isolated features for consistent alignment during PCB mounting.
The 50-Ohm impedance is standard for RF test equipment, telecom infrastructure, and instrumentation — match it to a 50-Ohm system for proper return loss. The 4 GHz frequency ceiling covers common bands; beyond 4 GHz the insertion loss climbs and VSWR degrades. The 500 V voltage rating is the working voltage for the polyethylene dielectric between centre conductor and shield. The 500 mating cycles reflect the gold-on-brass contact finish, which resists fretting corrosion through repeated connect/disconnect cycles.
The shield termination is solder — the braid or foil of the coax is soldered to the body, not crimped. The contact termination is also solder, meaning the centre conductor is soldered to the pin. This is a field-serviceable joint but takes more skill than a crimp-on BNC.
