New R Series Heat Sink Has Introduced from Ohmite

By adding a cam-clip and eliminating the need for a screw hole, the rear side of Ohmite’s new R Series heat sink benefits from being fully populated with extra fins which offer a larger cooling surface area and an improvement in thermal performance while using less space. Compared to a conventional heat sink, additional fins have been extruded by removing the necessity for a 12-mm access channel to the screw hole. In doing this, the company claims to have achieved better thermal performance for the 38-mm tall R2 heat sink compared to a similar heat sink without the cam-clip, in a package width that requires less space - 35.2 mm instead of 42 mm. The attachment mechanism is capable of attaching either a TO-220 or a TO-247 component, provides the same amount of force after repeated use, and is offered in both degreased and black anodized finishes, according to the company.

Ohmite Manufacturing Company has been a leading provider of resistors for high current, high voltage and high energy applications for over 80 years. The full complement of products includes wirewound, wire element, thick film, and ceramic composition resistors, in addition to variable voltage controls and heatsinks.
