Fin-Enhanced Heatsink Handles Higher Power Densities

Added fins on the rear side of Ohmite’s new R Series heatsink create a larger cooling surface area and significantly improve thermal performance—in less space. The extra fins come as a result of using a cam-clip, which thus eliminates the need for a 12-mm access channel to the screw hole. The 38-mm-tall R2 heatsink has a package width of 35.2 mm (instead of the typical 42 mm). The attachment mechanism can attach to either a TO-220 or TO-247 component.
