501503B00000G Description

Short technical summary and product information.

The 501503B00000G is a board level heat sink designed for cooling TO-3 semiconductor packages. It features a rhombus shape and is constructed from aluminum with a black anodized finish for enhanced thermal performance and corrosion resistance. The heat sink measures 1.880" (47.75mm) in length, 1.400" (35.56mm) in width, and has a fin height of 1.000" (25.40mm). It uses a bolt-on attachment method for secure mounting to the component.

 

Thermal performance is specified at 8.40°C/W under natural convection and improves to 2.00°C/W at 500 LFM forced air flow. The heat sink can dissipate 5.0W at a 40°C temperature rise. These characteristics make it suitable for applications requiring efficient heat removal from TO-3 power devices in both natural and forced air environments.
