The locking ramp fastening provides positive retention under vibration, a requirement for automotive-grade Fakra interconnects. ## Impedance and Frequency Range The 50 Ohm characteristic impedance matches standard RF system impedance for cellular, GNSS, and Wi-Fi signal paths. The 4 GHz maximum frequency covers most automotive RF bands (/L5 GNSS at 1.2-1.6 GHz, cellular LTE/5G sub-6 GHz, and ISM bands at 2.4 GHz) with margin. Shield termination is via solder to the connector body, providing a continuous ground path from the cable braid through the mated interface. Through-hole mounting gives a mechanically robust solder joint compared to SMT, important for connectors that experience cable strain during assembly or service. ## Housing and Keying The housing comes in violet and claret colours — these correspond to the Fakra Code D keying standard. In a multi-connector harness, the colour-coding and mechanical keying prevent inserting a GPS antenna plug into a cellular radio port. The single-port design keeps the footprint compact for dense PCB layouts in telematics control units.","metaTitle":"Amphenol RF FA1-NDSP-PCB-2 SMB/Fakra Plug, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF FA1-NDSP-PCB-2 SMB/Fakra plug, 50 Ohm impedance, 4 GHz max frequency, through-hole solder termination, locking ramp, gold plating, -40°C to 85°C.","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 D","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Violet, Claret","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":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"FA1-NDSP","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":"$3.5173","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6ee6ee375daa9494d1c027d4db373fce.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/FA1-NDSP-PCB-2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the FA1-NDSP-PCB-2 connector?","answer":"The FA1-NDSP-PCB-2 is available to order through independent distribution channels.
