The Arlon TC350 Thermally Conductive PCB delivers exceptional thermal management and structural reliability for demanding electronic designs. Manufactured with a specialized ceramic-filled PTFE composite, this high-performance substrate features a dielectric constant (DK) of 3.50 at 10 GHz. It addresses the common challenge of heat dissipation in high-power circuits by offering a thermal conductivity of 0.72 W/m-K. This enables product developers to minimize hot spots, lower component junction temperatures, and significantly extend the operating lifespan of power-dense electronics.
Key Features of Arlon TC350
