The press-fit shield and contact termination means no solder wicking into the dielectric — the PTFE insulator stays clean, and the impedance holds through the launch. This matters for automated assembly lines and high-reliability backplanes where a rework-free press-fit joint is preferred over a hand-soldered one. Rated to 2 GHz, this jack covers 3G-SDI video, CATV head-end gear, and baseband broadband distribution. The 500 V rating is the dielectric withstand between centre contact and shell — well above the signal levels in those applications, but it confirms the PTFE insulator is thick enough for the creepage path. ## Cable Compatibility and Construction This jack is spec'd for the RG-122 cable group. RG-122 is a 75 Ohm coax with a solid or stranded centre conductor and a foam or solid polyethylene dielectric — common in video patch panels and closed-circuit TV distribution. If you are using RG-59, the physical dimensions (centre pin diameter and dielectric OD) are close but not identical; the press-fit contact is sized for the RG-122 centre pin, so verify the cable's centre conductor diameter against the jack's contact before committing. The body is zinc with a nickel finish — nickel provides good corrosion resistance for indoor equipment racks and patch bays, though it is not rated for outdoor salt-fog exposure. Gold-over-beryllium copper gives the contact spring a long fatigue life and low contact resistance over those cycles — a solid choice for a patch panel that sees regular re-patching. The PTFE dielectric maintains its dielectric constant across that range, so the impedance shift is minimal.","metaTitle":"TE Connectivity 5221336-3 BNC Jack, 75 Ohm, Press-Fit, 2 GHz","metaDescription":"TE Connectivity 5221336-3 BNC jack, 75 Ohm impedance, press-fit termination, 2 GHz max frequency.
