Aluminum Electrolytic Capacitors are widely used in diversified industries. Their main component is the aluminum oxide magnesium layer that forms on the surface of the anode during a special passivation process, and this layer acts as an insulating dielectric. The 381EL181M400J452 is an aluminum electrolytic capacitor, and it has a number of advantages, including exceptional performance in terms of frequency response, lower leakage current, and relatively low ESR (Equivalent Series Resistance).

The 381EL181M400J452 is designed for use in applications involving relatively high levels of interference, and it is particularly suited to power electronics and telecommunications. The capacitor can also be used in high power LED lighting systems, industrial motor drives, in home automation and robotics factories, and automotive applications including battery powered electric vehicles.

The 381EL181M400J452 aluminum electrolytic capacitor consists of a metal case, sealed with epoxy resin and hermetically sealed. Inside is an electrolyte solution of sodium hydroxide and a spiral wound anode and cathode. The two metal foil electrodes are separated by a separator made of nylon or paper and saturated with the electrolyte. The main advantage of this type of capacitor lies in its ability to store magnetism, meaning it can act as a low-impedance filter for ac, thereby suppressing interference.

The 381EL181M400J452 has a wide range of operating frequencies, and a wide temperature range, making it ideal for a variety of applications. It has low equivalent series resistance, making it ideal for high frequency circuits. It also has high capacitance, making it suitable for high power applications. Furthermore, it offers superior ripple current and ability to operate and retain its capacitance even at temperatures as low as -40°C. The capacitor also has a long life expectancy of up to 2000 hours at 105°C, meaning it can be used in environments with wide temperature changes, such as those encountered in high power automotive applications.

The working principle of the 381EL181M400J452 aluminum electrolytic capacitor is based on the principle of electrodeposition. This is a process in which electrochemically active substances are deposited on a surface. When an electrical current is applied to the capacitor, an electric field is created inside the electrolyte, generating ions that are electrodeposited on the anode and cathode. These ions are then stored in the environment formed by the dielectric layer on the anode electrode, and the electrolyte solution. The electric field between the two electrodes causes the dielectric layer to expand, and the electrons can then move between the two electrodes, creating a charge that is stored in the capacitors.

In summary, the 381EL181M400J452 aluminum electrolytic capacitor is designed for a wide range of applications, from telecom, industrial motor drives, and LED lighting systems, to the automotive sector. It has a wide range of operating frequencies, low equivalent series resistance, and high capacitance, as well as excellent ripple current and temperature stability, and it is capable of storing a charge in the environmentally friendly atmosphere provided by the dielectric layer. The working principle is based on electrodeposition, and when an electric field is created in the electrolyte, ions are electrodeposited on the anode and cathode, and the two metal electrodes are separated by a dielectric barrier that stores the electric charge.
