Aluminum electrolytic capacitors are polarized electrolytic capacitors. As they are polarized, they can only be connected one way around in a circuit as the electrolyte in the capacitor has a positive and negative terminal. The aluminum electrolyte capacitors are available in much higher capacitance values than ceramic or film capacitors. One example is the UWD1V220MCL1GS, which belongs to the aluminum electrolytic capacitors category.

The UWD1V220MCL1GS is a radial capacitor with an anode made from aluminum, a cathode made from aluminum and papaer, and an electrolytic solution as its dielectric. The capacitor has a voltage rating of 120-200 Vdc, a capacitance of 220μF, a ripple current of 1.1A at 85°C, and a lifetime of 20,000 hours.

The size of the UWD1V220MCL1GS is 8 x 11mm, making it suitable for use in smaller electronic devices where space is at a premium. The capacitor also features a large capacitance to size ratio and a very low Equivalent Series Resistance (ESR). These features make it a very suitable choice for power filtering applications such as power supplies and audio amplifiers, where space and performance are important considerations.

The working principle of an aluminum electrolytic capacitor is very straightforward. When voltage is applied to the capacitor, an electric field will be created between the anode and cathode, which will attract and separate positive and negative ions from the electrolyte. This increase in electric field causes a current to flow between the electrodes, with the electrolyte acting as a dielectric. The ions formed will form a thin layer of charged particles on the electrode surfaces, which is known as the capacitance. As the voltage is increased, the capacitance will also increase and the capacitor is effectively charged.

The benefits of using aluminum electrolytic capacitors are numerous. They are able to maintain high capacitance values despite their small size. Additionally, as aluminum is a good conductor, the UWD1V220MCL1GS has very low ESR, making it ideal for power filtering applications. Its long lifetime, low ESR and high capacitance can also make it an excellent choice for a variety of applications. These include power supplies and audio amplifiers, as well as energy storage inverters and electronic ballasts.

In conclusion, the UWD1V220MCL1GS is a radial capacitor with a voltage rating of 120-200 Vdc, a capacitance of 220μF, a ripple current of 1.1A at 85°C, and a lifetime of 20,000 hours. Its size of 8 x 11mm and its high capacitance to size ratio make it ideal for power filtering applications such as power supplies and audio amplifiers. The working principle of an aluminum electrolytic capacitor is based on the electric field generated between its anode and cathode, which attracts and separates positive and negative ions from the electrolyte to form a thin layer of charged particles. The capacitor offers excellent performance due to its long lifetime, high capacitance and low ESR, making it suitable for a variety of applications.
