Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum ceramic capacitors, are components that are present all over the world in our everyday lives. These devices, formally known as UPB1H220MDD1TD, have been the focus of research, development and application for decades. In this article, we take a look at their application field and working principle.

Application Field

Aluminum electrolytic capacitors are widely used in areas where high capacitance and high stability of capacitance-temperature characteristics are required. These components are also used when a high ripple current or a large voltage capacity is needed. UPB1H220MDD1TD is a common type of aluminum electrolytic capacitor, and is widely used in energy harvesting, power conditioning converters, snubbing circuits and other DC power circuits.

Working Principle

Aluminum electrolytic capacitors are designed around three basic components: an anode, a dielectric and a cathode. The anode is made from aluminum foil and the cathode is typically made from a wet electrolyte solution. The dielectric is usually an organic film. When the aluminum foil comes into contact with the wet electrolyte, it forms an Alloy-Oxide-Electrolyte (AO) layer on the aluminum surface, which acts as a barrier layer between the anode and the electrolyte.

Capacitance is created when the anode and cathode are placed together, with the dielectric layer in between them. The dielectric layer acts as a barrier, while the electrolyte allows electric current to pass through it. As current passes through the electrolyte, electric charge is stored in the dielectric layer. The larger the gap between the anode and cathode, the larger the capacitance.

The main feature of aluminum electrolytic capacitors is that the capacitance value is stable over a wide temperature range. This is because the capacitance is determined by the surface area of the aluminum foil and the density of the electrolyte. When the temperature changes, the volumetric capacity of the electrolyte changes, thus maintaining a stable capacitance value.

A further advantage of aluminum electrolytic capacitors is that they are able to withstand high ripple current. The ripple current is mainly caused by the alternating voltage and current frequencies, and is inversely proportional to the frequency of the alternating current. Aluminum electrolytic capacitors have a high ripple current capacity and can therefore withstand high-frequency electric signals.

Conclusion

Aluminum electrolytic capacitors are widely used in a variety of applications, due to their high capacitance, stable capacitance-temperature characteristics, and high ripple current resistance. UPB1H220MDD1TD is a common type of aluminum electrolytic capacitor and is used in a variety of DC power circuits. Their working principle is based on three components: an anode, a dielectric layer, and a cathode. As current passes through the electrolyte, electric charge is stored in the dielectric layer, and the capacitance is determined by the surface area of the aluminum foil and the density of the electrolyte.
