The snap-on coupling gives a quick, positive mate for panel or board-edge connections that see periodic disconnect — test points, patch panels, or field-service access points. Rated to 12 GHz, this jack covers the full L-band through Ku-band for satellite IF distribution and DOCSIS upstream bands. The gold-plated brass body and beryllium copper center contact with gold plating deliver the 500-cycle mating life. That cycle count is typical for the MCX class, but the gold-on-gold interface means the contact resistance stays stable through those cycles — important for a 75 Ohm line where a degraded return loss from a worn contact would show up as a reflection in the passband.","metaTitle":"919-415J-71P12G MCX Jack, 75 Ohm, 12 GHz, Through Hole","metaDescription":"Amphenol 919-415J-71P12G MCX jack, 75 Ohm impedance, 12 GHz max frequency, gold body, snap-on fastening, through-hole solder termination.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"MCX","Frequency - Max":"12 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"91941","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":"$8.3400","stockQuantity":22,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/818100df1b8c72e05a57531c9a51c253.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can 919-415J-71P12G be used for 50 ohm systems?","answer":"No. The 919-415J-71P12G is a 75 Ohm connector. Mating it with a 50 Ohm cable or connector creates an impedance mismatch that degrades return loss, especially above 1 GHz.
