B60-075-AE

B60/C60 Series Heat Sink System Ohmite introduces the power C series heat sink with improved Cam N Lock spring clip (Pat. Pending). This series offers flexible, high performance and compact heat sink with exchangeable cam clip system for TO-220, 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.
