It is the flange-mount member of the HRM series, with a threaded fastening interface and a single port. The connector is rated from DC to 12.4 GHz with an insertion loss of 0.1 dB, and is specified for 1000 mating cycles — well above the 500-cycle baseline typical of economy SMA parts, indicating gold-over-beryllium copper contacts that hold up in test-equipment or field-service environments where the connector is mated and unmated regularly. The silver housing colour is the natural stainless finish — no plating to flake or wear in harsh environments. The 12.4 GHz maximum frequency covers the entire X-band (8–12 GHz) and most Ku-band satellite downlinks, with headroom to 12.4 GHz. The 0.1 dB insertion loss at the connector interface is low enough that a single mated pair adds negligible attenuation in a short cable assembly — the loss budget is dominated by the RG-405 cable itself, not the connector. For comparison, a standard SMA jack with a brass body and tin plating might spec 0.3 dB at 12 GHz and 500 cycles; the Hirose HRM holds 0.1 dB and 1000 cycles through the gold-plated beryllium copper contact and stainless body. ## Termination and Cable Preparation — Solder Shield, Solder Contact Both the shield and center contact are solder-terminated. The shield termination uses a solder cup or ferrule that accepts the RG-405 braid; the center contact is a solder-post design. For a harness builder, this means the cable end must be stripped to expose the center conductor and dielectric to the correct length — typically 0.125\" for the center pin and 0.200\" for the shield — and soldered with a controlled-temperature iron to avoid melting the PTFE dielectric. The flange mount uses two through-holes for #4 or M2.5 screws; the panel cutout is a standard SMA D-hole per MIL-STD-348.","metaTitle":"Hirose HRM-100-3S(09) SMA Jack, 50 Ohm, 12.4 GHz","metaDescription":"Hirose HRM-100-3S(09) SMA jack, female socket, 50 Ohm, DC to 12.4 GHz, 1000 mating cycles, gold-plated beryllium copper contact, panel mount with flange","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":"-","Impedance":"50Ohm","Body Finish":"-","Cable Group":"RG-405 (.085\\\" Semi Rigid)","Body Material":"Stainless Steel","Housing Color":"Silver","Mating Cycles":"1000","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"12.4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","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":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.5000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/HRM-100-3S(09)/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the HRM-100-3S(09) and how is it quoted for volume purchases?","answer":"The HRM-100-3S(09) is sourced to order against an RFQ through independent distribution.
