BNC Plug (Male) Termination Load, DC-4GHz 5W VSWR 1.25

BNC Termination Load Plug (Male) | DC to 4 GHz | 50 Ω

The ROSNOL T-B15-4G5WA/133 is a high-power BNC termination load designed for 50 Ω RF systems operating up to 4 GHz. It supports a DC to 4 GHz frequency range with a maximum VSWR of ≤ 1.25, providing effective impedance matching and controlled signal reflection. Rated for 5 W average power at 25 °C, this termination is suitable for RF testing, calibration, and signal conditioning where higher dissipation capability is required. The bayonet-lock coupling mechanism ensures secure mechanical connection and stable RF performance during repeated use.

This model features a brass center contact with gold plating over a nickel underlayer to ensure reliable conductivity and long-term durability. The connector body and coupling nut are manufactured from brass with nickel plating for mechanical robustness and corrosion resistance. A PTFE insulator provides stable dielectric performance, while an integrated aluminum heat sink with anodized surface treatment supports effective thermal dissipation. A silicone rubber gasket enhances mechanical stability and sealing. This termination load is widely used in RF test equipment, laboratory measurement systems, telecommunications infrastructure, and high-power signal verification environments.

ROSNOL RF termination loads are manufactured under ISO 9001-certified quality management systems and comply with RoHS and REACH regulations. Offering consistent quality, dependable electrical performance, and competitive pricing, ROSNOL products provide a cost-effective alternative to leading European and American RF component brands. Comprehensive customization services, including materials, plating, and mechanical design options, are available to meet specialized RF application requirements.
