Description
SMA Short with Chain | Jack (Female) | 50 Ohm
The ROSNOL SMA2AS50-1270A-88.9/9Q is a precision RF test accessory designed to provide a defined short-circuit termination with a nominal impedance of 50 ohms. By directly shorting the center conductor to the outer conductor, this accessory establishes a known electrical reference condition for RF and microwave measurement systems. It features an SMA jack (female) configuration with a screw-lock coupling mechanism and an integrated retaining chain to support secure handling and prevent accidental loss. The component supports operation from DC to 18 GHz and is specified for use within a temperature range of −65 °C to +165 °C.The ROSNOL SMA2AS50-1270A-88.9/9Q is manufactured with a stainless steel body finished in gold plating over a nickel underlayer. The center contact is produced from beryllium copper with gold plating over a nickel underlayer, supporting reliable electrical continuity. A silicone rubber gasket and a passivated stainless steel retaining chain are incorporated to enhance mechanical stability and durability. Mechanical dimensions are provided in millimeters with inch references, and standard manufacturing tolerances are applied to ensure consistency across production units.
Produced under ISO 9001-certified quality systems, ROSNOL SMA Short with Chain accessories fully comply with RoHS and REACH directives. These precision RF test components deliver consistent and well-defined short-circuit reference states and serve as a cost-effective alternative to comparable products from leading global manufacturers. Customization services for materials, plating, and mechanical design are available upon request.
