576802B03100G Description

Short technical summary and product information.

The 576802B03100G is a board-level heat sink designed for cooling TO-220 and TO-262 semiconductor packages. Manufactured by Aavid, it features an aluminum construction with a black anodized finish for enhanced thermal emissivity.

 

Key thermal specifications include a natural convection thermal resistance of 27.30°C/W and 7.00°C/W at 400 LFM forced airflow, with a power dissipation rating of 1.0W at a 30°C temperature rise. Mechanical dimensions are 12.70mm fin height, 12.70mm width, and 19.05mm length, with a rectangular fin shape.

 

The heat sink attaches using a clip and PC pin mounting method, making it suitable for horizontal plug-in PCB layouts. It is compatible with both TO-220 and TO-262 package styles and is intended for low-power thermal management applications such as voltage regulators and power transistors.
