The bayonet lock mates fast and holds under vibration, and the bulkhead front-side nut mount lets you fix the jack to a panel before terminating the solder connection. The board-edge, end-launch mounting option also allows direct PCB integration without a pigtail. ## Sizing the RF Path: Impedance, Frequency, and Insertion Loss The 75 Ohm impedance and 0.2 dB insertion loss are specified for 3 GHz max. The PTFE dielectric and BNC geometry define the upper frequency limit. Two mounting paths: board-edge end-launch for direct PCB solder, or bulkhead front-side nut mount for panel fixing. The shield termination is solder, so you'll need a soldering iron and a clean ground pad — no crimp or clamp.","metaTitle":"Amphenol 112775-75 BNC Jack, 75 Ohm, 3 GHz, 500 Cycles","metaDescription":"Amphenol 112775-75 BNC jack, 75 Ohm impedance, rated to 3 GHz with 0.2 dB insertion loss. 500 mating cycles, -65°C to 165°C.","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":"Board Guide","Includes":"-","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":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"3 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"112775","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/874bdfd42a4404abb67e46ce97745e9a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/112775-75/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 112775-75?","answer":"The impedance is 75 Ohm, designed for video, broadcast, and data-com systems that use a 75 Ohm characteristic impedance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/112775-75","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/112775-75 when reusing this data.
