The centre contact crimps onto the centre conductor, the ferrule clamps the braid and jacket, and the shield termination is crimped — no solder, no clamp. The 500-cycle mating life is generous for a field-service connector; the gold-plated centre contact keeps the signal path clean through those cycles. ## RF Performance — 75 Ohm at 4 GHz For a video or broadband signal chain, the 75 Ohm match matters: a 50 Ohm plug on a 75 Ohm cable creates a reflection at the junction. This plug keeps the impedance continuous through the mated pair.","metaTitle":"Amphenol RF 031-80103 BNC Plug, 75 Ohm, 4 GHz, NRND","metaDescription":"Amphenol RF 031-80103 BNC plug, 75 Ohm, rated to 4 GHz.
