Shield termination is solder — the outer braid of the coax solders to the shell body. The center contact termination is also solder, accepting the signal conductor. The PTFE dielectric maintains consistent impedance through the interface. ## Temperature Range and Construction The center contact material is beryllium copper — chosen for its spring properties and resistance to relaxation over repeated mating cycles — plated with gold for corrosion protection and low contact resistance.","metaTitle":"Amphenol RF 031-70526-21 BNC Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70526-21 BNC jack, 75 Ohm, female socket, rated to 12 GHz. 500 mating cycles, gold-plated beryllium copper center contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Board Edge, End Launch; Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Connector Style":"BNC","Frequency - Max":"12 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-70","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":"$8.7633","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d3a25472313d64776a9e4f309eea7902.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-70526-21/alternatives.json"},"ai":{"faq":[{"question":"Can 031-70526-21 be used for panel mount?","answer":"Yes, the jack supports panel mount with a bulkhead front-side nut.
