It carries a 2 GHz frequency ceiling and a 300 V voltage rating, with a bayonet lock for quick connect/disconnect in patch-panel or bulkhead applications. ## 75 Ohm impedance — the defining spec The 75 Ohm impedance sets this jack apart from the more common 50 Ohm BNC. It is the standard impedance for composite video, SDI, CCTV, and broadcast distribution — not for RF or telecom where 50 Ohm is the norm. Mating a 75 Ohm jack with a 50 Ohm plug introduces a 1.5:1 VSWR mismatch that degrades signal quality, so confirm the system impedance before specifying. ## Through-hole mounting and solder termination This jack mounts through the PCB and terminates with solder cups on the center contact and shield. The through-hole footprint provides mechanical retention against cable strain at the board edge — a common failure point for surface-mount RF connectors. The shield termination is soldered directly to the ground plane, which keeps the return path short and the impedance transition clean.","metaTitle":"TE Connectivity 1274571-1 Mini BNC Jack, 75 Ohm","metaDescription":"TE Connectivity 1274571-1 mini BNC jack, 75 Ohm impedance, 2 GHz max frequency, 500 mating cycles.
