574902B03700G Description

Short technical summary and product information.

The 574902B03700G is a board level vertical heat sink designed for cooling TO-220 packages. It features a rectangular finned shape and is constructed from black anodized aluminum, providing effective heat dissipation in a compact form factor.

 

With dimensions of 34.93mm length, 21.84mm width, and 10.03mm fin height, this heat sink offers a thermal resistance of 6.00°C/W under forced air flow at 400 LFM and 16.00°C/W under natural convection. It can dissipate up to 2.5W at a 40°C temperature rise.

 

The heat sink attaches to the component using a clip and PC pin method, ensuring secure mounting on the PCB. Its vertical orientation is suitable for applications where airflow direction aligns with the fins for optimal cooling performance.
