This is a single-port connector, impedance-matched to 75 Ohms, with a max frequency of 2 GHz and insertion loss of 0.15 dB. The 75 Ohm impedance and 2 GHz ceiling match video and telecom signal paths. The 75 Ohm impedance matches video and telecom signal paths. The 2 GHz max frequency covers HD-SDI rates. The bayonet lock gives a positive mate with a quarter-turn; the 500-cycle rating means it'll hold up to regular reconnection in patch panels or field test points. ## Obsolete — Sourcing Reality For BOM lines that specify this exact order code, the sourcing path is the independent surplus and broker market. There is no official TE cross-reference or direct successor part number on record for this specific 75 Ohm, Belden 8218-crimped variant. ## Compatibility and Cross-Reference The 221185-3 is specifically listed for Belden 8218 cable — a 75 Ohm RG-59/U type coax commonly used in CCTV and baseband video. The crimp dimensions and dielectric fit are matched to that cable's jacket and core diameters.","metaTitle":"TE 221185-3 BNC Plug, 75 Ohm, Crimp","metaDescription":"TE Connectivity 221185-3 BNC plug, male pin, 75 Ohm, 2 GHz, 500 V, crimp termination for Belden 8218.
