The gold-over-beryllium copper center contact resists fretting corrosion over those cycles, keeping contact resistance stable. ## 1 GHz Ceiling vs MMCX Alternatives The MSS-R-PC(40) is rated to 1 GHz maximum frequency, while the MMCX-R-PC(40) sibling from the same Hirose catalog runs to 6 GHz. Both are 50 Ohm snap-on receptacles with gold-plated brass bodies and PTFE dielectric, but the MSS series trades frequency headroom for a higher mating-cycle count — 3000 cycles versus 500. If your signal stays under 1 GHz and the connector will be cycled often, the MSS-R-PC(40) covers the job without over-specifying bandwidth you do not need.","metaTitle":"Hirose MSS-R-PC(40) 50 Ohm RF Receptacle, 1 GHz, 3000 Cycles","metaDescription":"Hirose MSS-R-PC(40) 50 Ohm RF receptacle, female socket, snap-on, 1 GHz max, 3000 mating cycles, gold-plated brass body, PTFE dielectric, through-hole solder","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":"MSS","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"3000","Mounting Type":"Through Hole","Connector Type":"Receptacle, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"MSS","Frequency - Max":"1 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"MSS-R","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":"$12.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d02ebaa8609caede4277041a636f02da.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many mating cycles does MSS-R-PC(40) support?","answer":"The MSS-R-PC(40) is rated for 3000 mating cycles, which is high for a snap-on RF connector and suits frequent-disconnect applications like test ports."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/MSS-R-PC~140~2","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/hirose-electric-co-ltd/MSS-R-PC~140~2 when reusing this data.
