Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which use a thin aluminum oxide layer as the dielectric. The oxide is formed as the result of a chemical etching process which is performed on an etched aluminum foil. The impressed voltage polarizes the capacitor and forms the oxide layer in an electric field. Thus, the capacitance of an aluminum electrolytic capacitor depends on the applied voltage, temperature and frequency. Due to their improved capacitance per volume ratio compared to other types of capacitors, aluminum electrolytic capacitors are widely used in electronic circuits.

UPB2G100MPD1TD analysis

The UPB2G100MPD1TD refers to a type of aluminum electrolytic capacitor produced by TDK Corporation. This particular type of capacitor is a polar type due to its two terminals, which are known as the plus (+) and minus (−). This polar type of capacitor features a high DC voltage rating of 100V as well as a very low ESR of 0.2 ohms. Other specifications of the UPB2G100MPD1TD include a capacitance of 0.1µF, a temperature range of -40°C to 125°C, and a lifetime of up to 2000 hours.

Application Fields

The UPB2G100MPD1TD capacitor is suitable for a wide range of applications such as high-voltage power supplies, signal processing, protection circuits, and various automotive and industrial electronic applications. It is especially suitable for high-voltage DC-DC converters which require high capacitance and low ESR ratings. This capacitor is also suitable for applications in pulse circuits, clock oscillators, and the power supply segment for data communication. In addition, its low ESR makes it suitable for high-frequency circuits.

Working Principle

An aluminum electrolytic capacitor is a polarized electronic component, meaning that the device is capable of storing an electric charge only if the terminals are connected with the right polarity. The charge is stored in the electrolyte solution of the capacitor and is discharged through the aluminum oxide layer. This layer creates the dielectric, which is usually created through an electrochemical process (i.e. anodization).

The operation of the UPB2G100MPD1TD capacitor is based on the principle of Faraday’s Law of Induction. The voltage impressed on the terminals of the capacitor causes an electric field to form between the plates of the capacitor. This electric field causes a polarization of the electrolyte and thus forms the dielectric. This action allows the capacitor to store energy which can be released as an electric current. The current is able to travel in either direction depending on the polarity of the applied voltage.

Conclusion

The UPB2G100MPD1TD capacitor from TDK Corporation is a special type of aluminum electrolytic capacitor with a very low ESR and high capacitance. It is suitable for a wide range of applications, including high-voltage power supplies, signal processing, and automotive and industrial electronics. It operates according to Faraday’s Law of Induction by forming an electric field between two plates and creating a dielectric in the electrolyte solution. The capacitor is able to store and release energy as an electric current depending on the polarity of the applied voltage.
