Stamped Heat Sinks
Ideal for lower power PCB cooling, CUI Devices’ stamped heat sinks are made from aluminum or copper with black anodized or tin-plated material finishes. Supporting a variety of transistor packages, our stampings are available in sizes from 8 to 50.8 mm with heights from 4 to 25.4 mm. Our stamped heat sinks are measured under four conditions for thermal resistance and carry power dissipation ratings from 2.1 up to 10.29 W at 75°C.
