That 3 GHz ceiling is the key selection gate: if your application requires the full 6 GHz bandwidth (e.g., 5G NR or dual-band Wi-Fi), step up to one of the 6 GHz-rated Fakra variants. For GPS /L5, 4G LTE, AM/FM, and SDARS, the 3 GHz ceiling leaves headroom. The Code K keying is unique to this variant — it physically prevents mating with a Code A, C, or D receptacle, so the keying code must match the harness-side connector.","metaTitle":"2FA1-NKSP-PCBB6 Amphenol RF SMB Fakra Plug, 50 Ohm, 3 GHz","metaDescription":"Amphenol RF 2FA1-NKSP-PCBB6 SMB Fakra plug, Code K keying, 50 Ohm impedance, 3 GHz max frequency, through-hole solder termination.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Tray","Features":"Code K","Includes":"-","Impedance":"50Ohm","Body Finish":"Tin","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Curry","Mating Cycles":"100","Mounting Type":"Through Hole","Connector Type":"Plug, Male Pin","Fastening Type":"Locking Ramp","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":"Solder","Base Product Number":"2FA1","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/450932754517be1ebb333adca169b2fb.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2FA1-NKSP-PCBB6/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 2FA1-NKSP-PCBB6?","answer":"The 2FA1-NKSP-PCBB6 is a 50 Ohm connector, matched to standard 50 Ohm RF cable and PCB trace impedance."},{"question":"What is the body material of 2FA1-NKSP-PCBB6?","answer":"The body is zinc die cast with a tin finish."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/2FA1-NKSP-PCBB6","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/2FA1-NKSP-PCBB6 when reusing this data.
