The impedance is fixed by the dielectric geometry in the polypropylene (PP) insulator, so there is no field adjustment. The 500 mating cycles mean the gold-plated phosphor bronze center contact holds up to repeated connect-disconnect in test racks or patch panels without the center pin wearing loose. The right-angle through-hole termination exits the rear of the body, so the solder tails sit parallel to the PCB — plan the board layout so the signal trace transitions cleanly from the 75 Ohm launch. Panel mount via the bulkhead — the front-side nut clamps the jack to the panel, and the zinc die-cast body with nickel finish provides the ground reference and shielding. The PP dielectric stays stable across that span — no dielectric creep or impedance drift at the temperature extremes. Supplied in bulk packaging — order by the piece for prototype or low-volume builds. No reel or tray to handle.","metaTitle":"Amphenol 31-71043-1010 BNC Jack, 75 Ohm, 1 GHz, Bulkhead","metaDescription":"Amphenol 31-71043-1010 BNC jack, 75 Ohm impedance, 1 GHz max frequency, 0.2 dB insertion loss.
