The PTFE dielectric keeps the signal path stable across the band, and the 50 Ohm impedance holds the line against the board trace when the launch geometry is right. ## Right-Angle PCB Mount — Board Layout Consideration The 500-cycle mating rating is standard for SMA; the gold-over-beryllium copper center contact holds its spring force across those cycles without the fretting you'd see with a plain brass contact. The difference is the body material: the 901-143-6RFX uses brass, while the 901-144 uses stainless steel. For most bench and indoor applications, brass is fine — it's cheaper and machines well. Stainless steel gives better corrosion resistance and mechanical strength for outdoor or high-vibration environments, but it costs more and is harder to solder to. If the BOM calls for brass and the application is benign, stick with the 901-143-6RFX. If the environment is aggressive or the connector sees repeated torque, the 901-144 is the safer call.","metaTitle":"Amphenol 901-143-6RFX SMA Jack, 50 Ohm, 18 GHz, Right Angle","metaDescription":"Amphenol 901-143-6RFX SMA jack, female socket, 50 Ohm impedance, 18 GHz max frequency, right-angle through-hole mount, gold-plated brass body, 500 mating","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":"500","Mounting Type":"Through Hole, Right Angle","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"901-14","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b49758cacb0e180ae56393eba69cd3bf.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-143-6RFX/alternatives.json"},"ai":{"faq":[{"question":"What is the frequency range of the Amphenol 901-143-6RFX?","answer":"The 901-143-6RFX is rated to 18 GHz maximum frequency.
