It's built for RG-402 (.141\" semi-rigid) cable, which means the centre conductor and dielectric dimensions are matched to the 50 Ohm line from the connector through the cable transition. The 18 GHz max frequency is the usable bandwidth; above that the VSWR rises past the typical 1.3:1 limit for this class of SMA. The gold-plated brass centre contact and stainless steel body give this plug the corrosion resistance and mating cycle life (1000 cycles) you need for test equipment, instrumentation, or any interconnect that sees repeated connect-disconnect. This is a complete assembly kit — the package includes the connector body, coupling nut, gasket, and spring washer. No crimp tool needed, just a soldering iron and the correct RG-402 cable prep dimensions from the Hirose HRM series drawing.","metaTitle":"HRM-101S(09) SMA Plug, Male Pin, 50 Ohm, 18 GHz, Active","metaDescription":"Hirose HRM-101S(09) SMA plug, male pin, 50 Ohm impedance, 18 GHz max frequency, RG-402 cable fit, 1000 mating cycles, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"HRM","Package":"Bulk","Features":"-","Includes":"4 pcs - 1 Connector, 1 Coupling Nut, 1 Gasket, 1 Spring Washer","Impedance":"50Ohm","Body Finish":"-","Cable Group":"RG-402 (.141\\\" Semi Rigid)","Body Material":"Stainless Steel","Housing Color":"Silver","Mating Cycles":"1000","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"HRM","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C~125°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/HRM-101S(09)/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of HRM-101S(09)?","answer":"The HRM-101S(09) is a 50 Ohm SMA plug.
