💡 Pro-Tip for High-Power Projects
Because of its 165mm length, this heat sink is capable of cooling multiple components at once (such as a row of power transistors or several LED chips). To ensure even cooling, space your components evenly across the surface and always use a high-quality thermal interface material (TIM) for the best heat transfer.
