The female socket accepts a standard BNC plug, and the brass body with silver plating gives good RF conductivity and corrosion resistance for indoor and sheltered outdoor equipment. ## Where is this connector used? The BNC interface and 50 Ohm impedance make this jack a natural fit for RF test equipment, instrumentation, telecom base station backhaul, and broadcast video gear. The bayonet lock is faster to mate than a threaded connector — good for panel faces that get frequent reconfiguration. 50 Ohm is the standard impedance for RF transmission lines — matching this jack to a 50 Ohm cable and system avoids reflections that eat signal power. The 4 GHz ceiling covers most cellular bands (LTE, 5G sub-6 GHz), Wi-Fi, and GPS L-band; above 4 GHz the insertion loss climbs and the VSWR degrades. Silver-plated center contact and body keep surface resistivity low at those frequencies — tin or nickel would add loss. ## Lifecycle and sourcing — this part is obsolete The 1-1478204-0 is listed as Obsolete. If you need a form-fit-function replacement, the Greenpar series includes other 50 Ohm BNC jacks with the same bayonet lock and through-hole solder termination; confirm the footprint and panel cutout against your board layout before substituting.","metaTitle":"TE Greenpar BNC Jack 1-1478204-0, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity Greenpar BNC jack, 50 Ohm, 4 GHz max, 500V, bayonet lock, through-hole solder.
