Extruded Heat Sinks
CUI Devices’ extruded heat sinks offer aluminum fin structures and greater surface area for increased heat dissipation in higher power applications. Our extruded heat sinks feature power dissipation ratings from 1.93 up to 16.7 W at 75°C and are measured under four conditions for thermal resistance. Made from aluminum with a black or blue anodized finish, our extruded heat sinks are compatible with TO-218 and TO-220 transistor packages.
