Large Aluminum Heatsink - 4" x 4" x 1.75"

This large aluminum heatsink is capable of some serious head dissipation. It measures 4" square with an overall height of 1.75". The thickness of the base is .55"!
These heatsinks were designed to cool mosfets in high-end stereo audio amplifiers for a local manufacturer of high-end audio equipment. They have a 2 large holes bored through the base, each hole is .55" in diameter. There is a small hole in the center of the heatsink that is approximately .125" in diameter.

These are great heatsinks for high-power MOSFETs and diodes. They are easy to work with and have a large surface area. Mounting a 4" square fan on the top would increase the capacity even more. This heatsink weighs in at 1.18lbs!

Vetco has a limited supply of these heatsinks available. Once they are out of stock we will not be able to obtain more.
