The 534202B03453G is a board level heat sink designed for TO-220 packages. It features a rectangular, vertical fin design with a fin height of 0.500" (12.70mm), a length of 1.180" (29.97mm), and a width of 1.000" (25.40mm). The heat sink is constructed from aluminum with a black anodized finish, offering good corrosion resistance and thermal performance.
Thermal performance is characterized by a natural convection thermal resistance of 13.40°C/W and a forced air thermal resistance of 6.00°C/W at 300 LFM. At a 20°C temperature rise, the heat sink dissipates 1.0W. The attachment method uses clip and board locks, ensuring secure mounting to the board.
This heat sink is suitable for vertical board mounting and is intended for cooling TO-220 semiconductor packages in applications requiring efficient heat removal. The black anodized finish enhances radiation heat transfer and provides a durable surface.
Typical applications include power supplies, voltage regulators, and other electronic devices using TO-220 packages where thermal management is critical.
