Product Description

Thermal Conductivity Aluminum Nitride Ceramic Tube with Flange

Semiconductor RF devices, such as power amplifiers and transceivers, operate at high frequencies and power levels, generating significant heat that can degrade performance.

Our AlN special-shaped parts with 170 W/(m·K) thermal conductivity are the ideal thermal management solution for these critical components.

Manufactured from premium AlN ceramic sheets, these custom-shaped heat sinks, substrates and shielding parts efficiently dissipate heat,

maintaining device temperature within optimal ranges. Their low dielectric loss and excellent electrical insulation make them suitable for

high-frequency applications, minimizing signal loss and ensuring stable RF performance. Whether you need complex curved heat spreaders

or custom-fit insulation components, our AlN special-shaped parts are engineered to meet the unique requirements of 5G semiconductor devices,

driving the advancement of high-speed communication technology.
