Rated to 6 GHz, this jack carries the signal through a PTFE dielectric with a gold-plated beryllium copper center contact. The 500-cycle mating life is high for an MCX. The gold-plated brass body resists corrosion in humid or salt-spray conditions without an additional finish. The snap-on retention ring holds the connector body in place during wave or hand soldering — no additional hardware is needed. The board footprint must match the 50 Ohm impedance target; the datasheet layout shows the ground plane clearance and pad dimensions to keep the launch impedance controlled up to 6 GHz. Beryllium copper retains its spring force at elevated temperatures better than phosphor bronze, which matters for the 165°C upper operating limit.","metaTitle":"Amphenol RF 919-432J-51S MCX Jack, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-432J-51S MCX jack, female socket, 50 Ohm impedance, 6 GHz max frequency, through-hole solder termination, gold body, 500 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bag","Features":"-","Includes":"-","Impedance":"50Ohm","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":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"91943","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":"$6.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a234815416b79ffa9beca47ca200467c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/919-432J-51S/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of the 919-432J-51S?","answer":"The 919-432J-51S is a 50 Ohm MCX jack, rated to 6 GHz maximum frequency."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/919-432J-51S","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/919-432J-51S when reusing this data.
