Description
SMA Short with Chain | Plug (Male) | 50 Ohm
The ROSNOL SMA1AS50-1270A-88.9/9QQ is a precision RF test accessory designed to provide a defined short-circuit termination with a nominal impedance of 50 ohms. This accessory establishes a direct electrical short between the center and outer conductors, creating a stable reference condition for RF and microwave test environments. It features an SMA plug (male) configuration with a screw-lock coupling mechanism and an integrated retaining chain, supporting secure attachment and preventing loss during handling. The component is specified for operation from DC to 18 GHz and is designed for use across a temperature range of −65 °C to +165 °C.The ROSNOL SMA1AS50-1270A-88.9/9QQ is constructed with a stainless steel body and coupling nut, both finished with gold plating over a nickel underlayer. The center contact is manufactured from beryllium copper with gold plating over a nickel underlayer to ensure stable electrical contact characteristics. A silicone rubber gasket supports mechanical sealing, while the stainless steel retaining chain is passivated to enhance corrosion resistance. All dimensions are specified in millimeters with inch equivalents, and standard manufacturing tolerances are applied to ensure consistent product geometry.
ROSNOL SMA Short with Chain accessories are manufactured in ISO 9001-certified facilities and are fully compliant with RoHS and REACH requirements. Designed as precision RF test components, they deliver well-defined short-circuit reference characteristics while offering a cost-effective alternative to comparable accessories from established international brands. Customization options for materials, plating, and mechanical configuration are available upon request.
