Aluminum Electrolytic Capacitors are an important component of many electronic circuits. They can be found in a number of electronics, from televisions and radios to computers, cell phones, and portable audio devices. The 381LX391M200K012 is an aluminum electrolytic capacitor designed for applications requiring large capacitance values. This capacitor has a range of capacity from 0.12mF to 200mF with a rated voltage of 400V.

A capacitor stores electrical energy in an electric field and consists of two conductive plates separated by an insulating dielectric material. The two conductive plates have a positive and a negative electrical charge, which creates an electric field between them. When voltage is applied to the capacitor, the positive and negative charges within the dielectric material will be attracted or repelled, depending on the polarity of the external voltage. This will cause the electric field to expand or contract, thus increasing or decreasing the capacitance.

Aluminum electrolytic capacitors use electrolyte to separate the conductive plates instead of dielectric. This makes them ideal for storing large amounts of charge, which are then released when needed. Their performance is highly dependent on the temperature of the environment, which can result in changes in capacitance and leakage currents. As with other types of capacitor, an aluminum electrolytic capacitor should be used in accordance with its rated capacity and voltage. The 381LX391M200K012 is specifically designed for high capacitance and high voltage applications.

The main advantage of this capacitor is its extremely large capacitance rating. It has a range of capacitance values from 0.12mF to 200mF, with a nominal voltage of 400V. With such high capacitance, the 381LX391M200K012 is suitable for power supplies, voltage control circuits, filtering circuits, and snubber circuits. The capacitor is also available with a variety of case styles, such as radial and snap-in, making it perfect for a variety of applications.

In addition to high capacitance, the 381LX391M200K012 features low losses and high capacitance stability over temperature and time. The capacitor is built with a solid aluminum case for durability and uses an insulated sleeve for protection against corrosion and moisture. The capacitor also features a wide temperature range, making it suitable for extreme environments.

The working principle of the 381LX391M200K012 is simple. When voltage is applied to the capacitor, positive and negative charges accumulate in the electrolyte, creating an electric field between the two conductive plates. This electric field stores electrical energy, which is released when the voltage is removed. As the voltage continued to be applied, the charges accumulate and the capacitance increases. When the voltage is removed, the charges gradually decrease, causing the capacitance to decrease.

The 381LX391M200K012 aluminum electrolytic capacitor is a reliable and efficient component for a variety of high capacitance applications. With a wide range of capacitance, low losses, and high capacitance stability over temperature and age, this capacitor is an excellent choice for power supplies, voltage control circuits, filtering circuits, and snubber circuits.
