PI49 Black Anodized Aluminium Heat Sink for TO-220 – 4-Fin 22x16x12.5mm

The PI49 20mm Black Anodized Aluminium Heat Sink is a high-performance thermal management solution specifically engineered for TO-220 package components including MOSFETs, voltage regulators, IGBTs, and power ICs. Its 4-fin extruded design with 1 mm thick blades rapidly draws heat away from the component junction, while the black anodized finish increases emissivity for faster radiative cooling compared to raw aluminium. Weighing only 4.57 g, it delivers excellent thermal dissipation without adding significant bulk or PCB stress. For best results, apply thermal grease between the component and heat sink; use a mica washer and plastic bush if electrical isolation is required.
