Description
N Type High Power Termination Load Jack (Female) | DC to 4 GHz | 50 Ω | 100 W
The ROSNOL T-N25-4G100WA/H3 is an N Type termination load jack designed for high-power RF systems operating up to 4 GHz. It features a 50 Ω impedance and supports a frequency range from DC to 4 GHz with a maximum VSWR of ≤ 1.20 (Return Loss ≥ 20.83 dB). Rated for 100 W average power handling at 25°C, this termination load is suitable for terminating high-power RF outputs, protecting transmitters, and maintaining impedance stability in telecommunications infrastructure, broadcast systems, and RF test environments. The screw-lock coupling mechanism ensures secure mechanical connection during operation.The center contact is manufactured from phosphor bronze with gold plating to ensure reliable electrical conductivity under elevated current conditions. The connector body is constructed from brass with nickel plating for enhanced mechanical robustness and corrosion resistance. A PTFE insulator provides stable dielectric performance, while the integrated aluminum heat sink with black anodized finish supports efficient thermal dissipation during continuous operation. This mechanical structure is optimized for long-term stability in demanding RF applications.
ROSNOL high-power RF termination loads are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Offering robust RF performance, reliable thermal management, and competitive pricing, ROSNOL termination loads serve as cost-effective alternatives to products from leading European and American RF component brands. Customization services for power rating, materials, plating, and mechanical design are available upon request.
