Aluminum electrolytic capacitors are one of the most widely used electronic components in the world today. Taking the URS2A4R7MDD1TD as an example, the capacitance of the isolatable unit is 2.2μF with 4V DC voltage. It is typically made of an anodized aluminum foil as the anode, a paper dielectric and a solid electrolyte as the cathode. It has many uses, such as in power sources, DC-DC converters, inverters, and switches.

The aluminum electrolytic capacitor’s operation is based on the Faraday-Lenz Law; the capacitance of an ideal capacitor is determined by the ratio of the area of the plates that make up its electrodes to the distance between them. In aluminum electrolytic capacitors, the negatively charged foil conductor is the anode and the solid electrolyte acts as the cathode. When an electrical field is applied across the two plates, electric current passes through the electrolyte, generating a charge proportional to the applied voltage. Therefore, the capacitance is determined by the amount of current that is created. When the electrical field is reversed, the aluminum electrolytic capacitor behaves like a regular capacitor, storing the charge and releasing it when needed.

Aluminum electrolytic capacitors have many uses in various devices from audiovisual equipment to computers. Their ability to store large amounts of energy makes them ideal for applications that require short bursts of high power or where high-frequency ripple currents are present. Their wide voltage range and low impedance makes them especially suitable for pulsed power supplies. In addition, aluminum electrolytic capacitors are very cost-effective and their long operational life make them a great option for many applications that require reliable energy storage.
