The 50 Ohm impedance rating matches standard RG-58/RG-59 video, RF, and telecom coax, so it drops into a 50 Ohm signal path without introducing a mismatch. The nickel-plated body handles the RF shield continuity, and the gold-plated phosphor bronze center contacts keep the signal path corrosion-resistant through repeated connects. The 221551-3 ships in bulk packaging. The dielectric material is PTFE, which holds its dielectric constant across temperature better than nylon or polypropylene alternatives.","metaTitle":"TE 221551-3 BNC to BNC Adapter, 50 Ohm, Jack to Jack","metaDescription":"TE 221551-3 BNC jack-to-jack adapter, 50 Ohm impedance, female to female, nickel body, gold-plated contacts.
