The 4 GHz frequency ceiling covers most common RF bands including cellular, Wi-Fi, and ISM applications below 4 GHz. The bayonet lock provides a positive mechanical mate with the standard BNC plug; the internal switch feature (listed in the specs) is a switching BNC variant that opens or closes a circuit when the plug is inserted — useful for self-terminating or sense circuits in test fixtures.","metaTitle":"TE Connectivity 1274314-1 BNC Jack, 50 Ohm, 4 GHz, Obsolete","metaDescription":"TE Connectivity 1274314-1 BNC jack, female socket, 50 Ohm impedance, 4 GHz max, 500 mating cycles, through-hole, bayonet lock.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"Board Guide, Internal Switch","Includes":"-","Impedance":"50 Ohms","Body Finish":"Tin-Lead","Cable Group":"-","Body Material":"Zinc","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Obsolete","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1274314","Contact Termination":"Solder","Dielectric Material":"Polyphenylene Oxide (PPO)","Operating Temperature":"-65°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1274314-1 and how do I get a price?","answer":"The 1274314-1 is obsolete and sourced through the surplus and broker channel."},{"question":"What are the specifications of 1274314-1?","answer":"The 1274314-1 is a BNC jack, female socket, 50 Ohm impedance, rated to 4 GHz maximum frequency.
