The contact termination is solder for the centre pin, and the shield is crimped onto the cable braid. This is the standard field-termination method for semi-rigid and flexible coax: the centre conductor solders into the beryllium copper contact, and the crimp barrel secures the shield, providing both mechanical strain relief and a consistent ground path. The dielectric is PTFE, which provides a stable dielectric constant and low loss up to 20 GHz. ## Cable Group and Termination Fit This SMA jack is specified for cable group RTK 044. That is a specific coaxial cable construction — typically a 0.085-inch semi-rigid or a flexible cable with a 0.044-inch centre conductor. Before ordering, confirm that your cable's outer diameter and dielectric diameter match the RTK 044 dimensions; the crimp shield and solder contact are sized to that cable group. Using the wrong cable group will result in poor shield termination and impedance mismatch. The threaded fastening type provides a secure, vibration-resistant mate. The coupling nut on the mating plug must be torqued to the recommended value to achieve the rated 20 GHz performance and 500-cycle durability.","metaTitle":"Amphenol RF 901-10849 SMA Jack, 50 Ohm, 20 GHz, Free Hanging","metaDescription":"Amphenol RF 901-10849 SMA jack, female socket, 50 Ohm impedance, 20 GHz max frequency, free-hanging in-line mount, solder contact, crimp shield, gold body, 500","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":"Bag","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"RTK 044","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"20 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","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":"$13.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e3ca4a6ffbb75033e9563d889d8de2d8.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-10849/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 901-10849 connector?","answer":"The 901-10849 is available to order through independent distribution.
