If you want to heat sink a SoC, motor driver, linear regulator, FET or other surface-mount package part, you might find yourself struggling to find a good heat sink. These extra-tall extra-small mini heat sinks are easy to use and give you an extra thermal boost.

The heat sink is a 0.26" x 0.26" (6.75mm x 6.75mm) square with 3 tall 'fins' sticking out the top. The total height is 0.39" (10mm) but you can easily file it down if you need a shorter heat sink to fit in a case). Simply use the thermal tape included on the bottom of the heat sink. Ideal for medium flat BGAs, TSSOPs, QFNs, etc!

We do not have a datasheet for these heat sinks, but we believe the thermal resistance is approximately 80ºC/W
