This connector is suited for board-edge RF launch applications where a low-profile, quick-connect interface is needed — common in GPS modules, wireless infrastructure, and test equipment. ## What the 50 Ohm and 6 GHz Ratings Mean for Your RF Link The 6 GHz maximum frequency means this connector can pass L-band, S-band, and C-band signals up to the lower 6 GHz region without significant mismatch loss. The 0.1 dB insertion loss per mated pair is low enough that you can treat it as negligible in a short jumper or pigtail; it becomes a budget item only in long cascaded runs. ## Right-Angle Mount and Board Layout Fit The centre contact and shield legs are solder-terminated, so the PCB footprint must provide a ground-plane clearance for the 50 Ohm trace transition — the datasheet footprint is the reference. The snap-on fastening means no torque tool is needed for mating; the connector locks with an axial push and releases with a straight pull.","metaTitle":"Amphenol RF 919-119J-51AX MCX Receptacle, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-119J-51AX MCX receptacle, female socket, 50 Ohm impedance, 6 GHz max, right-angle through-hole, gold body, 500 mating cycles.","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":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole, Right Angle","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"MCX","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"91911","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":"$11.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/53c1cf2ae75348bca6ad209a0e4b4296.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/919-119J-51AX/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance and frequency rating of 919-119J-51AX?","answer":"The 919-119J-51AX is a 50 Ohm MCX receptacle rated to 6 GHz maximum frequency with 0.1 dB insertion loss."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/919-119J-51AX","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/919-119J-51AX when reusing this data.
