The gold-plated phosphor bronze centre contact and PTFE dielectric maintain a consistent impedance through the launch, so the transition from coax to PCB trace stays clean up to the 4 GHz ceiling. 500 mating cycles means it handles field-service reconnect duty without the centre contact fretting.","metaTitle":"Amphenol 112405-12 BNC Jack, 75 Ohm, 4 GHz, Through Hole","metaDescription":"Amphenol 112405-12 BNC jack, 75 Ohm impedance, 4 GHz max frequency, 500 mating cycles, through hole solder termination, gold-plated centre 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":"-","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"112405","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":"$2.2422","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dd2be680190d469af4201b24498f178a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/112405-12/alternatives.json"},"ai":{"faq":[{"question":"Is the 112405-12 50 ohm or 75 ohm?","answer":"This is the correct variant for video, broadcast, and telecommunications systems using 75 Ohm coaxial cable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/112405-12","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/112405-12 when reusing this data.
