Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a multitude of electronic devices and applications. Their construction is quite simple compared to other types of capacitors: an anode foil of aluminum, covered with a dielectric oxide film which is then wound with an electrolyte saturated separator paper. This oxide is not an electrical conductor and provides an excellent dielectric for the capacitor’s working principle.

These capacitors are polarized, meaning one side must be connected to a positive voltage and the other side to a negative in order for current to flow. This is why they are most often used in DC circuits since an AC voltage will cause the positive and negative voltages to switch, thus damaging the capacitors. In addition, they are able to store and hold a large amount of energy, making them incredibly useful for power supply applications.
