The OHMITE CSM Series heat sinks are economically priced solutions for thermal management of TO-220 devices and power resistors. Available in five configurations with surface areas ranging from 1188 to 6645 square millimeters, these heat sinks feature a black anodized surface treatment for optimal heat dissipation. They offer a range of thermal performance, solderable mounting feet, and multiple mounting hole options for versatile device attachment. For improved thermal performance, consider using thermal joint compound or phase change material between the heat sink and the device.
