The voltage rating is 500 V, adequate for the signal levels in video and telecom gear, though the limiting factor at 4 GHz is the dielectric breakdown at the launch, not the bulk rating.","metaTitle":"112740-12 Amphenol RF BNC Jack, 75 Ohm, 4 GHz, Bulkhead","metaDescription":"112740-12 Amphenol RF BNC jack, 75 Ohm, 4 GHz, 500 mating cycles, gold body.
