The 0.3 dB insertion loss across the band keeps the link budget tight for automotive-grade Fakra applications like GPS, satellite radio, or cellular antenna feeds. ## Cable Prep and Termination Checklist Crimp termination for both shield and center contact — the shield is crimped over the ferrule, the center contact is crimped to the stripped conductor. The free-hanging (in-line) mount and latch-lock fastening mean the mated pair stays engaged without a secondary nut, but the 100-cycle mating life is a reminder that this is a field-serviceable connector, not a permanent solder joint. The Code B keying prevents cross-mating with other Fakra color codes in multi-antenna harnesses.","metaTitle":"FA1-NBSJ-C04-6 Amphenol RF SMB Fakra Jack, 50 Ohm, 6 GHz","metaDescription":"FA1-NBSJ-C04-6 Amphenol RF SMB Fakra jack, female socket, 50 Ohm, DC to 6 GHz, 0.3 dB insertion loss, crimp termination for RG-58/LMR-195.","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 B","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":"Cream","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-NBSJ","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":"$3.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d070412a21755d7d6c114f893e40ba1f.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/FA1-NBSJ-C04-6/alternatives.json"},"ai":{"faq":[{"question":"What cable groups are compatible with FA1-NBSJ-C04-6?","answer":"FA1-NBSJ-C04-6 is compatible with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups."},{"question":"What is the impedance of FA1-NBSJ-C04-6?","answer":"The impedance is 50 Ohm, matching standard RF system requirements for GPS, cellular, and satellite radio feeds."},{"question":"How many mating cycles does FA1-NBSJ-C04-6 support?","answer":"FA1-NBSJ-C04-6 is rated for 100 mating cycles, suitable for field-service and reconnection in harness assemblies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/FA1-NBSJ-C04-6","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/FA1-NBSJ-C04-6 when reusing this data.
