The Amphenol RF 3FA1ENASJ-C04ES is an SMB Fakra jack, female socket, terminated with a solder contact and a crimped shield. The IP67 rating means the mated pair is dust-tight and protected against temporary water immersion, so this connector suits exterior vehicle harnesses, roof-mount antenna cables, and washdown-area sensor links. The Code A keying is part of the Fakra standard, ensuring the correct color-coded housing mates only with its matching receptacle — a non-negotiable fit for production harness builds. ## Cable Compatibility and Termination This jack is designed for a specific cable group: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The crimp shield termination and solder contact work with the 50 Ohm impedance of these cables, so the signal path stays matched through the transition from cable to connector. The free-hanging in-line mounting means the connector is terminated to the cable end, not to a panel or PCB — it is the cable-side half of the mated pair. ## Mating Cycles and Field Service The gold-plated center contact on phosphor bronze resists corrosion and maintains contact resistance over those cycles.","metaTitle":"Amphenol RF 3FA1ENASJ-C04ES SMB Fakra Jack, 50 Ohm, 3 GHz","metaDescription":"Amphenol RF 3FA1ENASJ-C04ES SMB Fakra jack, female socket, 50 Ohm impedance, 3 GHz max, IP67 sealed, crimp shield termination, solder contact.","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 A","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907","Body Material":"Zinc Die Cast","Housing Color":"Black, Jet","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":"IP67 - Dust Tight, Waterproof","Shield Termination":"Crimp","Base Product Number":"3FA1ENASJ","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~105°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7826","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/29684f664a5b0d0c3600192153da186d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3FA1ENASJ-C04ES/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the Amphenol RF 3FA1ENASJ-C04ES and what is the price?","answer":"Pricing and current stock levels are confirmed at the time of quotation — no firm price or stock count is published here."},{"question":"Is the 3FA1ENASJ-C04ES a 50 Ohm connector?","answer":"Yes, the 3FA1ENASJ-C04ES carries a 50 Ohm impedance rating, making it suitable for matched-impedance RF signal paths such as antenna feeds and GPS modules."},{"question":"Which cables are compatible with the 3FA1ENASJ-C04ES?","answer":"The connector is designed for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables.
