“The aluminium electrolytic capacitors are very reliable in this application and fulfil the requirements of our specifications. This design ensures that the base of the capacitor is flat despite the adjacent heat shrink tube. Air inclusions are therefore reduced, which would hinder dissipation of heat from the capacitor to the heat sink.
