Rated for 2 GHz maximum frequency and 500 mating cycles, with gold-plated center contacts on brass and a nickel-plated brass shell. The PTFE dielectric keeps insertion loss stable across the band. This is a same-series adapter — BNC in, BNC out — so no impedance or interface conversion is involved. ## 75 Ohm impedance — not a 50 Ohm part The 75 Ohm impedance is the critical spec. This adapter is designed for 75 Ohm systems — video, broadcast, CATV, and legacy telecom — not the 50 Ohm test-equipment world. Using it in a 50 Ohm chain creates a 25 Ohm mismatch at the tee, which will reflect signal energy and degrade the return loss. If your system is 50 Ohm, you need a 50 Ohm BNC T-adapter; the 1-1337458-1 is not electrically interchangeable. ## Obsolete — sourcing through surplus channels No official successor or replacement part number has been assigned. Sourcing is limited to surplus inventory and broker channels — the factory is no longer producing this adapter. Gold-over-brass center contacts handle the 500 mating cycle rating without significant wear — suitable for test setups where the adapter is connected and disconnected regularly. Bayonet lock on both ends gives a quick, positive mate with standard BNC jacks and plugs.","metaTitle":"TE Greenpar 1-1337458-1 BNC T Adapter, 75 Ohm, 2 GHz","metaDescription":"TE Connectivity Greenpar 1-1337458-1 BNC T-adapter, 75 Ohm impedance, 2 GHz max, 500 mating cycles.
