It carries the Code B keying variant, which prevents cross-mating with other FAKRA color-code positions in the same harness bundle. Rated for 50 Ohm impedance and a maximum frequency of 3 GHz, this connector is built for automotive-grade RF interconnects — think GPS antennas, satellite radio, cellular telematics modules, and similar 50-Ohm signal paths inside a vehicle or equipment enclosure. ## Code B Keying — Why It Matters for Your Harness FAKRA connectors use a mechanical keying system — a color-coded plastic housing and a corresponding key on the mating receptacle — to ensure only the correct signal path gets connected. Code B on this plug corresponds to a specific color and key geometry. Code A (black, FA1-NARP-PCB-8) might be a cellular path, Code C (blue, FA1-NCRP-PCB-8) a satellite radio feed, and Code D (violet, FA1-NDRP-PCB-8) a diversity antenna. ## 3 GHz Bandwidth — What It Means for Signal Integrity The 3 GHz maximum frequency at 50 Ohm impedance covers most current automotive RF bands — GPS at 1.575 GHz, SiriusXM at 2.3 GHz, and 4G LTE cellular bands up to about 2.7 GHz. It does not reach the 6 GHz ceiling of the sibling FA1-NCRP-PCB-8, so if your design targets 5 GHz Wi-Fi or future 6 GHz automotive V2X bands, step up to that Code C variant. The gold-plated brass center contact and solder termination keep the signal path clean through the board interface. Through-hole mounting with solder termination for both the center pin and the shield.","metaTitle":"2FA1-NBSP-PCBB6 FAKRA SMB Plug, Code B, 50 Ohm, 3 GHz","metaDescription":"2FA1-NBSP-PCBB6 FAKRA SMB plug, male pin, Code B keying, 50 Ohm impedance, 3 GHz max frequency, through-hole solder termination, gold-plated center contact","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 B","Includes":"-","Impedance":"50Ohm","Body Finish":"Tin","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Cream","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","stockQuantity":22,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/450932754517be1ebb333adca169b2fb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does Code B mean on a FAKRA connector?","answer":"Code B is a mechanical keying and color-coding variant within the FAKRA standard.
