This is a surface-mount part, terminated by solder reflow to the board — no through-hole, so the RF launch sits on the top layer and the ground plane references the pad pattern underneath. ## 50 Ohm System Fit and 6 GHz Ceiling The 50 Ohm impedance matches the standard RF system impedance for wireless infrastructure, test equipment, and instrumentation — no impedance transformer needed at the interface. The 6 GHz frequency ceiling covers L-band, S-band, and mid C-band applications; the connector is usable up to that limit with the VSWR and insertion loss typical of an MCX interface. The 500 mating cycles rating reflects the snap-on design: the spring-loaded outer contact wears with each mate, but 500 cycles supports repeated test connections or field-disconnect scenarios without contact degradation. ## SMT Termination and Tape & Reel Packaging The shield and centre contact both terminate by solder — the shield ring solders to the board ground pads, the centre pin to the RF trace. Surface-mount termination keeps the component profile low and eliminates the need for a plated through-hole. The Tape & Reel and Cut Tape packaging options suit both high-volume pick-and-place lines and small prototype runs. ## Comparison: 919-382J-51P Bulk Variant The 919-382J-51P is electrically identical — same 50 Ohm MCX female socket, same 6 GHz ceiling, same gold-over-brass body and beryllium copper contact. For a high-volume reflow line, the Tape & Reel variant feeds directly into the feeder; for a manual or low-volume build, the Bulk variant avoids the tape handling step.","metaTitle":"Amphenol 919-384J-51PT MCX Jack, 50 Ohm, 6 GHz, SMT","metaDescription":"Amphenol 919-384J-51PT MCX jack, female socket, 50 Ohm impedance, 6 GHz max frequency, SMT solder termination, 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":"Tape & Reel (TR); Cut Tape (CT)","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Surface Mount","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":"91938","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":"$3.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/490d5556b66ad59eb871f0790502a3be.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/919-384J-51PT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 919-384J-51PT and what is the price?","answer":"The 919-384J-51PT is available to order against an RFQ.
