The 75 Ohm impedance sets it apart from the more common 50 Ohm BNCs, making it the right fit for video distribution, CCTV, and telecom baseband signal paths where the characteristic impedance of the cable and system is 75 Ohm. It carries a 2 GHz maximum frequency and a 500 V voltage rating, with a gold-plated phosphor bronze centre contact rated for 500 mating cycles. The body is nickel-plated zinc alloy, and the dielectric is polymethylpentene (PMP).
