287-1AB Description

Short technical summary and product information.

The Wakefield-Vette 287-1AB is a board level heat sink designed for cooling TO-220 semiconductor packages. Constructed from black anodized aluminum, it features a rectangular finned shape with a vertical orientation. The heat sink measures 29.97mm in length, 25.40mm in width, and has a fin height of 12.70mm. It offers a typical thermal resistance of 16.20°C/W under natural convection and 7.80°C/W at 200 LFM forced air flow. Power dissipation is rated at 4.0W for a 65°C temperature rise. Attachment is achieved via bolt-on and PC pin methods, allowing for secure mounting and wave soldering directly to the circuit board. This heat sink is suitable for space-constrained applications requiring efficient heat removal from TO-220 devices.
