Aavid 4426 is a heat spreader plate, made of a durable aluminum that is designed to evenly disperse and dissipate heat buildup. It features a slim profile and is compatible with many popular mounting methods, including 4-corner, bottom, and side mounting with no additional hardware. The 4426 is designed to provide uniform cooling for a wide range of sensitive electronic components. Its low profile design makes it ideal for space-constrained applications, such as inside enclosures or within other limited spaces. Additionally, the 4426 has a flat, smooth surface that allows for proper air contact and convection, further aiding in its thermal performance.
