The nickel-plated brass body and dual bayonet locks give it the standard BNC quick-twist feel; it hangs free on the cable, no panel mount required. The 50 Ohm impedance matches standard 50 Ohm BNC cable runs — the T splits the signal without an impedance bump at the junction. Silver-plated centre contacts hold up to repeated mating better than tin; the PTFE dielectric keeps the dielectric constant stable across temperature, so the 50 Ohm line holds from DC up through the BNC band.","metaTitle":"TE Connectivity 221988-1 BNC T Adapter, 50 Ohm, Jack to Jack","metaDescription":"TE Connectivity 221988-1 BNC T-adapter, 50 Ohm impedance, female to female, bayonet lock, free hanging.
