Using a cable outside this group means the strip length and crimp dimensions are unverified — the 50 Ohm impedance and pull-off force are only guaranteed within the listed group. The shield termination is a crimp ferrule over the braid; the centre contact is a separate crimp operation onto the signal conductor. ## 3 GHz Bandwidth and 100-Cycle Durability The 3 GHz max frequency covers most cellular, GNSS, and short-range wireless bands. Above 3 GHz the SMB interface geometry introduces mismatch loss. ## Code F Keying and Fakra Compatibility The Code F keying is one of the Fakra colour/slot variants — it prevents cross-mating with other Fakra codes (A, B, C, D, E, G, H, I, K, L) in the same harness bundle. The housing is brown, which is the visual identifier for Code F in the Fakra colour scheme. ## Materials and Operating Range Zinc die-cast body with tin finish, PTFE dielectric, brass centre contact with gold plating. The PTFE dielectric maintains stable impedance across the temperature range and resists moisture absorption better than nylon or PE dielectrics.","metaTitle":"3FA1-NFSJ-C04W6 SMB Fakra Jack, 50 Ohm, 3 GHz, Crimp","metaDescription":"Amphenol 3FA1-NFSJ-C04W6 SMB/Fakra jack, female socket, 50 Ohm impedance, 3 GHz max, crimp termination for RG-58/LMR-195.
