Description
BNC Termination Load Plug (Male) | DC to 4 GHz | 50 Ω | 50 W
The ROSNOL T-B15-4G50WA/133 is a precision-engineered BNC termination load plug designed to provide reliable impedance matching and signal absorption in RF and microwave systems. This termination features a nominal impedance of 50 Ω and supports a frequency range from DC to 4 GHz, with a maximum VSWR of ≤ 1.25 (Return Loss ≥ 19.08 dB), ensuring minimal signal reflection and stable system performance. Rated for an average power handling of up to 50 W at 25°C, it is suitable for terminating unused RF ports, protecting active components, and maintaining signal integrity during system operation and testing. The bayonet-lock coupling mechanism enables quick and secure connection, making it ideal for professional RF environments in telecommunications, test and measurement, wireless infrastructure, and laboratory applications.The termination load is constructed with carefully selected materials to ensure durability and consistent electrical performance. The center contact is manufactured from brass with gold plating over a nickel underlayer for low contact resistance and long-term reliability. The connector body is made of brass with nickel plating to provide mechanical strength and corrosion resistance. A PTFE insulator is used to maintain excellent dielectric properties across the specified frequency range. The integrated heat sink is made from anodized aluminum to enhance thermal dissipation during continuous power operation. The gasket utilizes silicone rubber to ensure environmental sealing, while the coupling nut is constructed from brass with nickel plating for robust mechanical engagement. With a compact and lightweight design, this termination load supports stable installation and reliable operation across a wide range of RF systems where consistent impedance termination is required.
ROSNOL RF termination loads are manufactured under ISO 9001-certified quality management systems and fully comply with RoHS and REACH regulations, ensuring high product quality and global environmental conformity. Designed to deliver dependable performance at competitive pricing, ROSNOL termination loads serve as a cost-effective alternative to products from leading European and American brands. Comprehensive customization services, including frequency range, power rating, materials, and plating options, are available to meet specialized RF and microwave application requirements.
