380LX821M200K022

Aluminum electrolytic capacitors are passive electronic components that are designed to store energy in electrical form. They are characterized by a relatively large capacity, high dielectric strength and convenient in structure. A typical aluminum electrolytic capacitor is the 380LX821M200K022.

Application Field

Aluminum electrolytic capacitors are widely used for industrial and consumer applications in a variety of industries, as they are capable of providing high capacitance and high voltage rating. Their most common application is to filter high signal frequencies, store electrical energy and provide charge and discharge support for circuits. They are also used in signal processing, signal amplifying and switching functions and in static electricity absorption.

Working Principle

Aluminum electrolytic capacitors are composed of a positively-charged electrolyte (anode) and a negatively-charged electrolyte (cathode) separated by a thin dielectric barrier. When a voltage is applied between the two electrolytes, electric current passes through the dielectric barrier and a space-charge field effect is generated. This space-charge field effect reduces the voltage applied to the capacitor so the electric current decreases and the capacitor is able to store energy.

The capacitor will lose its capacitance as the dielectric barrier degrades over time, resulting in a reduction in its capacity to store energy. This is why it is important to select the right type of capacitor for the specific application in order to ensure reliable operation and long service life.

Conclusion

In conclusion, the 380LX821M200K022 is a type of aluminum electrolytic capacitor that is suitable for applications that require high capacitance and high voltage rating. It works by using a space-charge field effect to reduce the voltage applied to the capacitor so that it can store energy. Even though its capacity will degrade over time, careful selection of the capacitor can ensure reliable operation and long service life.
