C60-075-AE

## **B60/C60 Series** 

## **Heat Sink System** 

Ohmite introduces the powerful B60/ C60 series heatsink with cam clip (Pat. Pending) or custom mounting. This series offers flexible, high performance and compact heat sink with exchangeable cam clip system for TO-247 and TO-264 devices. The built in lip is provided for mounting ease. The optional B series can be tapped for popular Ohmite resistors or other devices. These powerful heat sinks can be thru-hole soldered as a single or dual unit. The dual unit can be mated to a 60mm fan for greater thermal performance. It is the ideal type of heat sink for high power density and small size (3U or 4U) electronic packaging with forced convection.
