If you're mating and unmating daily in a test fixture, 500 cycles is a reasonable service life before you swap the board-mounted jack. The SMT shield termination and contact termination mean the connector reflows with the board — no hand-soldering the ground legs. The board-edge cutout mount requires a slot in the PCB; the connector body drops into that cutout so the center contact aligns with the microstrip trace. Match the PCB footprint to the Hirose drawing, and the impedance through the launch stays at 50 Ohm. The difference is the mounting: the MMCX-LR-SMT(40) is a board-edge cutout SMT part, while the MMCX-R-PC(40) is a through-hole PC-mount receptacle in bulk packaging. If your board has the edge cutout and you're reflowing, the LR-SMT is the one. If you're hand-soldering into a standard plated-through-hole pattern, the R-PC is the fit.","metaTitle":"Hirose MMCX-LR-SMT(40) MMCX Receptacle, 50 Ohm, 6 GHz, SMT","metaDescription":"Hirose MMCX-LR-SMT(40) MMCX receptacle, female socket, 50 Ohm impedance, 6 GHz max frequency, 500 mating cycles, SMT board-edge mount, gold plating, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"-","Package":"Tray","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":"Active","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","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 MMCX-LR-SMT(40)?","answer":"The MMCX-LR-SMT(40) is available to order through independent distribution.
