It is the single-port member of the 901-10 base series, terminated by soldering the center contact and shield to the board. The gold-plated brass body and PTFE dielectric are standard for this class — the 4 GHz upper frequency limit places it below the 18–26.5 GHz range of premium SMA parts, so it is a cost-matched choice for lower-band RF, Wi-Fi, or instrumentation links where the signal path stays under 4 GHz. ## Why the 200 Mating Cycles Matter At 200 mating cycles, this jack is rated for about half the duty of the 901-144 (500 cycles) or the 901-10735 (500 cycles) — both of which use beryllium copper contacts. The 901-10112 uses phosphor bronze for the center contact, which is a good conductor but work-hardens faster under repeated mate/unmate. For a test-point or a connector that sees occasional reconnection, 200 cycles is fine. For daily connect/disconnect in a production fixture, the 901-144 with beryllium copper and 500 cycles is the better endurance pick.","metaTitle":"Amphenol 901-10112 SMA Jack, 50 Ohm, 4 GHz, Through Hole","metaDescription":"Amphenol 901-10112 SMA jack, female socket, 50 Ohm impedance, 4 GHz max frequency, gold-plated brass body, 200 mating cycles.","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":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"200","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"901-10","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.8700","stockQuantity":16,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5113d834c40045662b92232cbeb027d1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance of 901-10112?","answer":"The 901-10112 is a 50 Ohm SMA jack, which is the standard impedance for RF test and communications systems.
