This is a 50 Ohm controlled-impedance interconnect rated DC to 6 GHz, suited for RF signal paths in telecom base stations, antenna feeds, test equipment, and broadcast gear where repeated connect/disconnect cycles are common. The extended insulation feature provides additional creepage distance between the centre conductor and the flange, supporting the 480 V voltage rating in higher-power RF applications. ## Panel Mount with Flange — Solder Termination Mounting is through a flange with a panel cutout, secured by the snap-on nut on the rear. The shield termination is solder — the outer conductor of the coax cable solders to the body shell, while the centre contact is a solder-cup termination for the signal wire. The dielectric is PTFE, which provides stable impedance up to 6 GHz and handles the -40°C to 80°C operating range without phase drift.","metaTitle":"Amphenol 930-112J-51S QMA Receptacle, 50 Ohm, 6 GHz, 480 V","metaDescription":"Amphenol 930-112J-51S QMA panel-mount receptacle, female socket, 50 Ohm impedance, 6 GHz max frequency, 480 V rating, 500 mating cycles, gold-plated beryllium","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":"Extended Insulation","Includes":"-","Impedance":"50Ohm","Body Finish":"White Bronze","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"480 V","Connector Style":"QMA","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"93011","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~80°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.8924","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d91f1dbcc195785cc6eb87abaa605ac4.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/930-112J-51S/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance and frequency range of the 930-112J-51S?","answer":"The impedance is 50 Ohm, and the maximum frequency is 6 GHz.
