Through-hole mounting (Mounting Type: Through Hole) with a solder cup for the center contact and a solder tab for the shield (Contact Termination: Solder, Shield Termination: Solder). The body is nickel-plated brass (Body Finish: Nickel, Body Material: Brass), the dielectric is PTFE (Dielectric Material: Polytetrafluoroethylene (PTFE)) — the same material used in low-loss coax, so the signal path stays clean up to the connector's rated frequency. The bayonet lock (Fastening Type: Bayonet Lock) gives a positive, tool-less mate that resists vibration loosening better than a threaded coupling in a panel-mount scenario.","metaTitle":"Amphenol 031-70249 Mini BNC Receptacle, 75 Ohm, Through Hole","metaDescription":"Amphenol 031-70249 is a 75 Ohm mini BNC receptacle, female socket, through hole mount, gold-plated center contact, 500 mating cycles.","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":"-","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Receptacle, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"BNC, Mini","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-70","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f129b5e175561de04c9d8fcf064750a2.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-70249/alternatives.json"},"ai":{"faq":[{"question":"Is 031-70249 a male or female connector?","answer":"The 031-70249 is a female socket (Receptacle, Female Socket).
