Wakefield Thermal, Inc. Heat Sinks 219-263B

Heat Sink TO-263 (D²Pak) Aluminum 2.0W @ 30°C Top Mount

The 219 Series heat sinks unique design (Patent Pending) combines the technology of automatically assembling the tin plated solderable wires/rods with that of extruded aluminum anodized heat sink body to configure these SMT heat sinks. Rods/wires named ""Rollers"" are mated mechanically to the heat sink body by forging to reduce the interface thermal resistance between the drains & heat dissipation body.

Features & Benefits

• Increased thermal performance up to 30% over bright copper heat sinks from improved radiation of the black finish
• Increased surface areas by 3 times therefore thermal performance up to 300% over the aluminum stamped heat sinks on markets
• Light weight aluminum construction allows faster pick and place assembly reducing the manufacturing cycle time
• Radius mounted “Rollers” are designed for maximizing heat transfer from component and to avoid “bottle neck” heat transfer like the Aluminum stamped heat sinks
