Get the most out of your regulators, transistors and other TO-220 packaged chips by clipping on a heat-sink. Your transistor or regulator may advertise it can handle high currents but when multiplied by the drop voltage, the Wattage may be too high for the bare chip! Most TO-220's can disipate about 2W's worth without a sink.

This basic, and easy-to-use 23°C/W sink will let you burn about 4 Watts of power through a TO-220 (assuming an ambient temperature of 25°C and max die temp of 150°C). No screws or thermal paste required. For more detailed calculations, check out the Daycounter heatsink calc

    I am using some Arduino power FETs, but they can get hot, So I bought some of these clip-on heat sinks. They clip on to the transistor as the name suggests making them very convenient, but they also have a skew hole so that they can be made permanent...

    Easy to clip on over the top of your transistors. Little fitting if you want to secure it as well, but I found on using it twice that it holds snuggly as is. (Posted on 1/08/2016)
