Packaging

Bulk

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-247 packages (TO-220

and TO-264 available). This powerful heat sink provides tool and

fixture free assembly operation, largest surface areas and small-

est space occupation. It is the ideal type of heat sink for high

power density and small size (1U or 2U) electronic packaging

with forced convention cooling.
