It belongs to the Blind-Mate Coaxial series and is designed for panel-mount applications with a flange. The adapter carries a 50 Ohm impedance and is rated to 9 GHz maximum frequency, making it suitable for test setups, antenna feeds, or board-level interconnects where a transition between these two miniature RF connector families is needed. ## Construction and Materials The body is machined from stainless steel, with a beryllium copper centre contact plated in gold. The dielectric is PTFE. The straight body style uses a combination of push-pull on the SMPM side and threaded fastening on the U.FL side. Rated for 500 mating cycles, the gold-over-beryllium copper contact pair handles repeated connect-disconnect duty without significant signal degradation. ## Environmental and Mechanical Ratings The panel-mount flange provides mechanical retention and strain relief for the cable assembly. The 500-cycle mating life is typical for a precision RF adapter — the gold plating on the centre contact resists fretting corrosion through the rated cycle count.","metaTitle":"TE 2408021-1 SMPM to U.FL Adapter, 50 Ohm, 9 GHz","metaDescription":"TE 2408021-1 between-series RF adapter converts SMPM plug to U.FL jack. 50 Ohm impedance, 9 GHz max frequency, 500 mating cycles, panel mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Straight","Series":"Blind-Mate Coaxial","Package":"Bag","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"-","Adapter Type":"Plug to Plug","Body Material":"Stainless Steel","Center Gender":"Male to Male","Mating Cycles":"500","Mounting Type":"Panel Mount","Adapter Series":"SMPM to U.FL (UMCC), AMC","Fastening Type":"Push-Pull, Threaded","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Between Series","Frequency - Max":"9 GHz","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Base Product Number":"2408021","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"U.FL (UMCC) Jack, Male Pin","Convert From (Adapter End)":"SMPM Plug, Male Pin"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$206.7900","stockQuantity":33,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/876e9d418ab57815d29e38cfd1ac4112.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 2408021-1 adapter and what is the lead time?","answer":"Current pricing, stock position, and lead time are confirmed at quote time — submit your BOM quantity for a same-day quote."},{"question":"What is the impedance of the 2408021-1 adapter?","answer":"The 2408021-1 is a 50 Ohm adapter, matching the standard impedance for most RF test and measurement systems, cable assemblies, and antenna feeds."},{"question":"How many mating cycles does the 2408021-1 support?","answer":"The adapter is rated for 500 mating cycles, supported by gold-plated beryllium copper centre contacts that resist wear and corrosion through repeated connect-disconnect operations."},{"question":"Is the 2408021-1 adapter panel mount?","answer":"Yes, the 2408021-1 is a panel-mount adapter with a flange for mechanical retention, suitable for bulkhead or enclosure mounting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2408021-1","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/te-connectivity-amp-connectors/2408021-1 when reusing this data.
