It belongs to the MMCX series of subminiature push-on RF connectors, specified for snap-on fastening and rated to 6 GHz. The gold-plated beryllium copper centre contact and gold body finish are standard for maintaining signal integrity through repeated matings — the 500-cycle rating covers field-service reconnects without contact degradation. ## Mounting and Footprint Notes This receptacle mounts to a board-edge cutout with surface-mount solder pads — not a standard through-hole or SMT-only footprint. The board-edge cutout means the connector body sits partly off the board edge, which affects the ground-plane keep-out zone. Layout engineers should verify the cutout dimensions against the Hirose product drawing before committing the PCB. ## Compatibility with Standard MMCX Cables The snap-on fastening and 50 Ohm impedance are standard MMCX interface dimensions, so this receptacle mates with any standard MMCX plug that follows the interface specification.","metaTitle":"Hirose MMCX-LR-SMT MMCX Receptacle, 50 Ohm, 6 GHz, Obsolete","metaDescription":"Hirose MMCX-LR-SMT MMCX receptacle, female socket, 50 Ohm impedance, 6 GHz max frequency, snap-on fastening, gold-plated beryllium copper contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Board Edge, Cutout; Surface Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Obsolete","Connector Style":"MMCX","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"MMCX-LR","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C ~ 85°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4fec356b471c7be2b5573c4fc217c4a6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the MMCX-LR-SMT?","answer":"The MMCX-LR-SMT is obsolete and sourced through the surplus and broker channel.
