Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as electrolytic capacitors, are polarized capacitors with relatively large capacitance values in which a thin aluminum oxide layer acts as the dielectric. Among all types of capacitors, they have the highest capacitance per volume. They are primarily used in high frequency and high voltage DC power conditioning, inverters, and power supplies within electronics.

The LKG1J392MESBAK is a type of aluminum electrolytic capacitor. This capacitor is a discreet capacitor which has a long-life performance, making it ideal for high-load, high-frequency use. In addition, it can operate over a wide temperature range and low impedance.

Application Field

This type of aluminum electrolytic capacitor is designed for digital devices, computer storage systems, communication process systems, solar power systems, UPS or other DC power supply systems. The capacitor is axial-lead type with epoxy resin sealed case. It operates at operating temperature range of -25°C to 85°C and -40°C to 105°C at rated voltage.

In computer systems, the LKG1J392MESBAK is mainly used to filter out signals, suppress current interference and static electricity, and smooth the voltage of the power supply. As a passive component, it wears out over time as more electricity passes through it. It is also an important part of the power supply circuit for video cards. The LKG1J392MESBAK is widely used in computer systems due to its superior features.

Working Principle

Aluminum electrolytic capacitors work by using the electrical double layer formed on an aluminum oxide film as the dielectric compared with other capacitors. Aluminum electrolytic capacitors are essentially two aluminum electrodes that have been separated by an insulating layer, an electrolyte solution and a porous organic material. When a voltage is applied to the capacitor, positive ions in the electrolyte solution form a conductive layer on the internal surface of the aluminum oxide film, forming a dielectric. This dielectric can be charged up to a certain voltage, and then the current flows through the conductive layer of ions, and so the capacitor works.

Because of its special structure, the capacitor has a large capacitance compared to its physical size. This makes it ideal for high frequency and high voltage applications. The disadvantage of this type of capacitor is that it is a polarized capacitor, meaning one end has a positive charge and the other end a negative charge. It also has a shorter lifetime than other types of capacitors and its working voltage is very low.
