          Comments about RadioShack TO-220/TO-202 Aluminum Heat Sink:

          I bought this product from a local radio shack without realizing the screw was not included with the product. I thought maybe a screw that is used to mount a CD drive in the computer would fit but the screw was slightly thicker. I went to radio shack to purchase the appropriate screw and it turns out that they do not sell the screw. I'm in the process of rebuilding a tube amplifier and the unavailability of this screw is preventing me from completing this project. DO NOT PURCHASE UNLESS YOU HAVE A SCREW THAT FITS.

          Comments about RadioShack TO-220/TO-202 Aluminum Heat Sink:

          This is a small heat sink with excellent thermal characteristics. It works well with TO-220 regulators operating at up to 500 MA and moderately rated power transistors. Although it isn't obvious at first glance, the heat sink can be securely mounted to a surface with 3mm machine screws driven into the two holes in the fins. Be sure to apply a thin film of thermal compound when mounting the device.

          poor documentation

                Comments about RadioShack TO-220/TO-202 Aluminum Heat Sink:

                I didn't buy it (yet) but I am basing this review on the poor online catalog listing. How can RS advertize a heat sink and not show a picture of the mounting surface. Even worse you do not tell the dimensions of the heat sink, nor the temperature specs. How can I possibly decide if it is right for my application without full intormation? Guess I will buy elsewhere...

                  Did it's job but not as well as expected.

                  I bought this along with two TIP3055 transistors(one as a backup) to use in a small fluorescent lamp inverter.
                  The small size helps it fit into small areas.

                  The surface area suggests a higher performance than what really is. It still kept the transistor WELL below it's maximum temp but still rather hot.

                    I used 2 additional aluminum heat sinks to increase heat removal capacity from a silicon full wave bridge rectifier located on an LCD flat panel TV PC board. The original bridge rectifier burned out after only 3 years and needed to be replaced. The aluminum heat sinks had predrilled & threaded holes, making them very easy to mount.

                        The RS Part # 276-1368 is an excellent Heat Sink! I've been using it on LM7805 Voltage Regulators for years with not a single problem at all!
