It carries a 3 GHz frequency ceiling, which covers most automotive antenna feeds (GPS, SDARS, cellular) and short-reach RF interconnects where the SMB snap-on interface is preferred over a threaded SMA. ## Cable Prep and Termination The cable group list covers RG-59, 59B, 62, 140, 210, and Belden 8241, 8263, 8279, 9209. The 50 Ohm impedance of the connector matches the 50 Ohm cables in that group. ## Durability and Field Life Rated for 100 mating cycles — that is typical for an SMB-family connector and sufficient for a harness that is mated during vehicle assembly and rarely disconnected in service. The gold-plated centre contact handles the wipe without galling over that cycle count. The latch lock gives a positive tactile click when fully seated; there is no secondary lock or TPA.","metaTitle":"Amphenol 3FA1-NASJ-C65W0 SMB/Fakra Jack, 50 Ohm, 3 GHz","metaDescription":"Amphenol 3FA1-NASJ-C65W0 SMB/Fakra jack, female socket, 50 Ohm impedance, rated to 3 GHz.
