Silver 15*10*20/15*10*25mm 1Pin Aluminum Heat Sink For TO-220Triode

Heat sinks are used in almost all circuits that we encounter these days. The general purpose of a heat sink is to cool down some components used in a circuit that may heat up extensively and may burn if not cooled down. The nice thing about these heat sinks is that they wrap around the triode that you what to cool down to provide you with optimal cooling when the circuit is in use.
