## **VM Series Variable Mount Heatsink Series**
Ohmite introduces this new versatile heatsink design. This new design can accommodate several different industry packages. This design also lets the customer choose a mounting style using screws or clips for secure mounting to the heatsink. These one of a kind heatsinks are offered in a vertical (free convection cooling) or horizontal format (forced convection cooling) to fit customer applications.
