The 50 Ohm impedance and 18 GHz frequency ceiling place it in the standard SMA performance band, suitable for microwave test leads, module pigtails, and short-jump interconnects inside an instrument chassis. ## Cable Fit and Assembly This plug is built for RG-405 (.085\" semi-rigid) cable — the common 0.085-inch diameter copper-clad steel coax used in RF assemblies where the cable holds its shape after bending. The center contact and shield are both solder-terminated, which is the standard method for semi-rigid: you strip the cable, solder the pin to the center conductor, and solder the shield to the connector body. The threaded coupling nut provides a vibration-resistant mate to any standard SMA jack. ## Signal and Mechanical Ratings Rated for 50 Ohms nominal impedance and 18 GHz maximum frequency, this plug holds the impedance through the launch when the cable prep and solder joint are clean. Voltage rating is 335 V, which is typical for SMA connectors at this impedance level.","metaTitle":"TE Greenpar SMA Plug 1-1478904-0, 50 Ohm, 18 GHz, RG-405","metaDescription":"TE Connectivity Greenpar SMA plug, male pin, 50 Ohm impedance, 18 GHz max, for RG-405 .085\" semi-rigid cable. 500 mating cycles, gold body.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"Greenpar","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Contact, 1 Insulator","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"RG-405 (.085\\\" Semi Rigid)","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"335 V","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1478904","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0400","stockQuantity":45,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/961778760bdfa244c49cfe59e5ca5e9f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What cable does 1-1478904-0 work with?","answer":"This plug is designed for RG-405 (.085\" semi-rigid) cable — the 0.085-inch diameter semi-rigid coax.
