Ohmite introduces the C series (Pat. Pending). This  
series offers high performance, low cost and a  
compact heat sink with an integrated camming clip  
system for TO-126, TO-220, TO-247 and TO-264  
devices. This powerful heat sink provides tool and  
fixture free assembly operation, largest surface areas •ꢀDesignꢀFlexibilityꢀMaximumꢀflexibilityꢀforꢀdynamicꢀ
