The adapter is supplied as a three-piece kit: the connector body, a lockwasher, and a mounting nut, so the buyer gets a complete panel-install package in one order code. ## Signal path and construction The 75 Ohm impedance is the key selection parameter here — this adapter is built for video distribution, CCTV, and telecom baseband applications where the characteristic impedance of the cable and system is 75 Ohm. It is not a 50 Ohm part, so it should not be used in a 50 Ohm RF path without an impedance mismatch penalty. The frequency ceiling is 2 GHz, which covers standard-definition video, composite video, and many telecom signals, but does not reach into the higher bands used by modern data-over-coax or satellite IF stages. The centre contacts are female-to-female, silver-plated phosphor bronze, and the body is machined brass with a silver finish. The fastening type is bayonet lock on both ends, so the mating BNC plugs twist and lock with the standard quarter-turn. The mating cycle rating is 500 cycles, which is typical for a bulkhead adapter that gets reconfigured occasionally during maintenance or system rework — not a daily-mate test port, but adequate for a fixed installation that sees periodic cable swaps. No official cross-reference or pin-compatible alternate is on record; the BOM should specify this exact TE order code.","metaTitle":"TE Connectivity 1-1478045-0 BNC Jack-Jack Adapter, 75 Ohm","metaDescription":"TE Connectivity 1-1478045-0 BNC female-to-female bulkhead adapter, 75 Ohm impedance, 2 GHz max, silver-plated brass body.
