This matters in multi-connector automotive harnesses where GPS, satellite radio, and cellular share the same dashboard zone. The cable group covers the common 50 Ohm coax types: RG-58, LMR-195, Belden 9907.","metaTitle":"Amphenol RF 3FA1-NESJ-C04W0 SMB/Fakra Jack, 50 Ohm, 3 GHz","metaDescription":"Amphenol RF 3FA1-NESJ-C04W0 SMB/Fakra jack, female socket, 50 Ohm impedance, 3 GHz max frequency, Code E keying, crimp termination, free-hanging, 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":"Tray","Features":"Code E","Includes":"-","Impedance":"50Ohm","Body Finish":"Tin","Cable Group":"RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907","Body Material":"Zinc Die Cast","Housing Color":"Green, Leaf","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Jack, Female Socket","Fastening Type":"Latch Lock","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMB, Fakra","Frequency - Max":"3 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"3FA1-NESJ","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4645","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3FA1-NESJ-C04W0/alternatives.json"},"ai":{"faq":[{"question":"What does code E mean on 3FA1-NESJ-C04W0?","answer":"Code E is a Fakra keying variant that uses a green/leaf housing colour and a specific mechanical key shape.
