RS PRO Heatsink, +17.9°C/W, 20 (H) x 35 (W) x 20 mm (L)


Dissipate unwanted heat away from an electronic device with this heatsink from RS PRO. It helps to prevent overheating in items such as motherboards and ensures the good working function of an electrical circuit.
The unit is made of aluminium, which is a good thermal conductor and quickly attracts heat away from electronic components. Its specially designed fins have a large surface area to allow unwanted heat to easily rise, spread and dissipate. The lightweight product is simple to install and is also compact and space-saving.
You'll frequently find a heatsink like this one used in CPUs (Central Processing Units) where it plays a vital role in keeping electronic circuitry cool. This product is Restriction of Hazardous Substances (RoHS) compliant as it contains only negligible amounts of any harmful materials.
