Aluminum electrolytic capacitors are available in both polarised and non-polarised versions and are characterized by their very high capacitance values, large operating temperatures ranges, high stability and long service life. The 381LX103M035J052 is part of this family of capacitors, where the first three numbers indicate capacitance value of 100,000uF, the last two characters stand for voltage rating of 25V and the ‘J’ character stands for a temperature coefficient of -20%. In this article, we will discuss the application fields and working principle of 381LX103M035J052 aluminum electrolytic capacitor.

Application Fields

Aluminum electrolytic capacitors have a wide range of applications. Here are a few of the main application areas for the 381LX103M035J052 capacitor:

• Power Supplies – The 381LX103M035J052 capacitor is often found in power supplies as it offers a very good combination of high capacitance, low voltage rating and low temperature coefficient.
• Audio Equipment – Audio equipment often requires flat frequency response, low levels of noise and high dynamic range which the 381LX103M035J052 capacitor is able to provide.
• Automotive Electronics – Usually, the 381LX103M035J052 capacitor is used in automotive electronics in place of a more conventional style of capacitor due to its improved current and voltage handling capability, high temperature operation and improved stability.
• DC-DC Converters – DC-DC converters need high capacitance and low current leakage, making the 381LX103M035J052 capacitor a good choice for their application.

Working Principle

The principle behind the operation of an aluminum electrolytic capacitor is the same as any other type of capacitor. It works by having a pair of conductors separated by an insulator (dielectric). When an electric field is applied, an electric charge accumulates on the conductors on either side of the dielectric, thus creating an electrical capacitance between them. This capacitance stores an electrical charge and is released when the electric field is reversed.

The main difference between an aluminum electrolytic capacitor and other types of capacitors is the type of dielectric used. It uses an electrolytic (usually an aluminum oxide) dielectric instead of a plastic film or ceramic one which enables it to achieve a much higher capacitance. Furthermore, the electrolytic capacitor has a polarised design, meaning that it has a designated "+" and "-" terminals. This prevents the wrong polarity from being applied, which will significantly reduce the potential of failure.

Conclusion

The 381LX103M035J052 capacitor is an aluminum electrolytic capacitor with a capacitance value of 100,000uF, voltage rating of 25V and temperature coefficient of -20%. It is found in a wide range of applications including power supplies, audio equipment, automotive electronics and DC-DC converters. The working principle behind the 381LX103M035J052 capacitor is the same as any other type of capacitor, in that it works by having a pair of conductors separated by an insulator (dielectric). The electrolytic dielectric used in this type of capacitor allows it to achieve much higher capacitance values than other capacitors.
