Description
BNC Termination Plug 50 Ω | DC to 4 GHz | Bayonet Lock
The ROSNOL T-B15-4G1W/144 is a precision BNC termination plug designed for 50 Ω RF applications up to 4 GHz. Operating from DC to 4 GHz with a maximum VSWR of ≤ 1.2, it provides reliable impedance matching and reduced signal reflection for accurate RF performance. With an average power rating of 1 W at 25 °C, this termination is ideal for RF measurement, testing, and system validation. The bayonet-lock coupling mechanism ensures secure attachment and repeatable electrical performance.This model uses a brass center contact with gold plating over a non-magnetic nickel-phosphorus underlayer to achieve stable, low-resistance electrical contact. The body and coupling nut are manufactured from copper-tin-zinc alloy, offering excellent mechanical strength and corrosion resistance. A PTFE insulator ensures consistent dielectric behavior across the operating band, while a silicone rubber gasket enhances sealing and overall reliability. Compact size and precise construction make this termination suitable for telecommunications systems, RF laboratories, test equipment, and wireless infrastructure maintenance.
All ROSNOL RF termination products are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH directives. With high product quality, dependable performance, and competitive pricing, ROSNOL terminations are an ideal cost-effective alternative to leading European and American RF brands. ROSNOL also provides comprehensive customization services, including material, plating, and mechanical design options, to support diverse RF termination applications.
