The heat sink is a 0.25″ x 0.25″ (6.5mm x 6.5mm) square with 9 tall ‘fins’ sticking out the top. The total height is 0.5″ (12mm) but you can easily file it down if you need a shorter heat sink to fit in a case). Simply use thermal tape or a small amount of thermal paste to attach to the top of any flat chip. There is no thermal tape included with this product. 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 40-50ºC/W
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
