574502B03700G Description

Short technical summary and product information.

The 574502B03700G is a board level vertical heat sink designed for TO-220 semiconductor packages. It is manufactured by Aavid, Thermal Division of Boyd Corporation, and features an aluminum construction with a black anodized finish. The heat sink measures 0.750" (19.05mm) in length, 0.810" (20.57mm) in width, and has a fin height of 0.390" (9.91mm). It utilizes a clip and PC pin attachment method for secure mounting to the PCB. The thermal performance includes a typical natural convection thermal resistance of 21.20°C/W and improved 8.00°C/W at 400 LFM forced air flow. It can dissipate up to 3.0W at a 60°C temperature rise. The heat sink is RoHS3 compliant and has an MSL rating of 1 (unlimited). This heat sink is suitable for applications requiring efficient thermal management of TO-220 devices in space-constrained designs.
