581002B02500G Description

Short technical summary and product information.

This heat sink is designed for cooling TO-220 semiconductor packages in board level applications. It is constructed from aluminum with a black anodized finish, providing corrosion resistance and enhanced thermal emissivity. The heat sink measures 16.26mm in width, 25.40mm in length, and has a fin height of 16.26mm, making it suitable for vertical mounting on PCBs.

 

Thermal performance: natural convection thermal resistance is 17.4°C/W, improving to 4.00°C/W with 500 LFM forced air flow. Maximum power dissipation is 2.5W for a 50°C temperature rise. Attachment is achieved via bolt-on or PC pin methods, offering flexibility in assembly.

 

Typical applications include power supplies, motor drives, and voltage regulators where efficient thermal management of TO-220 devices is required. The vertical orientation allows natural airflow, and the black anodized surface aids in heat radiation.
