Ohmite’s R2 Series (patent pending) heatsink provides a large surface area along with our C Series clipping mechanism to attach to a TO-220, TO-247, or TO-264 package. The self-aligning features of the clip assure secure attachment and enhanced thermal performance. Because no screws are required for device mounting, additional fins can be added to the rear side of the heatsink for increased total surface area in a more compact space. The R2 series mounts vertically and has integrated solderable feet for easy mounting. The R2 series is available in degreased and anodized versions for even more thermal performance.
