The jack terminates to RG-58 and compatible cables (RG-58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907) using a crimp-on shield termination and a crimp contact. The latch lock provides vibration-resistant retention without a threaded coupling ring, making it suitable for automotive infotainment, telematics, and antenna interconnect applications where the Fakra interface is specified. ## What the 50 Ohm, 6 GHz Rating Means for Your RF Path The 6 GHz maximum frequency covers the 5 GHz Wi-Fi bands and GNSS/GPS signals. The 0.3 dB insertion loss at frequency is a per-connector budget figure. ## Cable Compatibility — RG-58 and Beyond The FA1-NCSJ-C04-0 is designed for RG-58 and its electrical equivalents: RG-58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. All share a similar 0.195-inch diameter dielectric and braid shield construction. The crimp ferrule and center contact are sized for this cable group. If you are using a cable outside this list, the crimp dimensions may not produce a reliable termination — verify the cable OD and dielectric diameter against the ferrule and contact specifications.","metaTitle":"FA1-NCSJ-C04-0 Amphenol RF SMB Fakra Jack, 50 Ohm, 6 GHz","metaDescription":"FA1-NCSJ-C04-0 Amphenol RF SMB Fakra jack, Code C keying, 50 Ohm, 6 GHz, 0.3 dB insertion loss, crimp termination, RG-58 cable group, gold center contact","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"Code C","Includes":"5 pcs - 1 Connector, 1 Contact, 1 Ferrule, 1 Housing, 1 Locking Clip","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907","Body Material":"Brass","Housing Color":"Blue, Signal","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Jack, Female Socket","Fastening Type":"Latch Lock","Insertion Loss":"0.3dB","Product Status":"Active","Connector Style":"SMB, Fakra","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"FA1-NCSJ","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~100°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5400","stockQuantity":26,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d070412a21755d7d6c114f893e40ba1f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What cables are compatible with the FA1-NCSJ-C04-0?","answer":"The FA1-NCSJ-C04-0 is compatible with RG-58, RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, and Belden 9907 cables.
