The gold-plated phosphor bronze body and brass center contact, plated with gold, handle the signal path with low loss through the rated band. Termination is SMT on both the shield and the center contact — the part reflows with the board in a standard solder profile. The shield termination is solder, so the ground connection is made directly to the PCB pad. The snap-on fastening engages with an audible click; the connector is not designed for repeated disconnect. The Liquid Crystal Polymer (LCP) dielectric holds up through reflow and the -40°C to 90°C operating range. ## What the 6 GHz and 20-Cycle Ratings Mean The 6 GHz frequency ceiling covers Wi-Fi 6E (5.925–7.125 GHz) and most sub-6 GHz 5G bands, but not mmWave. The 20 mating cycles are the practical limit for the gold-on-gold contact interface; after that the plating wear increases contact resistance and the snap-on retention loosens. For a production line that mates the cable once and never touches it again, 20 cycles is plenty. For a test fixture or a field-swappable antenna cable, look at the U.FL-R-SMT-1(40) which offers 30 cycles.","metaTitle":"Hirose X.FL-R-SMT-1(02) U.FL Receptacle, 50 Ohm, 6 GHz","metaDescription":"Hirose X.FL-R-SMT-1(02) U.FL (UMCC) receptacle, male pin, SMT, 50 Ohm impedance, 6 GHz max frequency, gold plating, 20 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"X.FL","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Phosphor Bronze","Housing Color":"Black","Mating Cycles":"20","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Male Pin","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"U.FL (UMCC)","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"X.FL","Contact Termination":"Solder","Dielectric Material":"Liquid Crystal Polymer (LCP)","Operating Temperature":"-40°C ~ 90°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the X.FL-R-SMT-1(02) in small quantities?","answer":"Submit an RFQ for your target quantity, and we will source it from the channel."},{"question":"Is X.FL-R-SMT-1(02) compatible with standard 50 Ohm RF cables?","answer":"Yes — the connector is rated for 50 Ohm impedance and mates with any U.FL (UMCC) plug that terminates a 50 Ohm coax cable assembly, such as the Hirose X.FL-PR-SMT1-2(80) plug."},{"question":"How many mating cycles does the X.FL-R-SMT-1(02) support?","answer":"The X.FL-R-SMT-1(02) is rated for 20 mating cycles.
