C40 Heat Sink System Datasheet

For TO-247, TO-264 and SOT-227 Packages

The C40 Series Heat Sink System (Patent Pending) offers flexible, high performance and compact heat sinks with an exchangeable cam clip system for TO247, TO-264 and SOT-227 (clip in development) devices. This powerful heat sink can be thru-hole soldered in single or paired configurations. The paired unit has mounting holes to accomodate a 40mm x 40mm fan. It is the ideal type of heat sink for high power density and small size (1U or 2U) electronic packaging with forced convection.
