LGJ2G181MELC20

Aluminum electrolytic capacitors, commonly known as aluminum electrolytic capacitors, consist of two metal aluminum foils filled with a special electrolyte, which has the characteristics of a large capacitance in a small size. The LGJ2G181MELC20 low profile SMD aluminum electrolytic capacitors with a snap-in terminal are particularly suitable for high density electronic equipment. This article will discuss the application field and working principle of LGJ2G181MELC20 aluminum electrolytic capacitors.

LGJ2G181MELC20 aluminum electrolytic capacitors are used in various electronic and electrical equipment. The device is widely used in the filter circuit, where the device can provide greater than 500,000 hours of operating life at 105°C or higher operating temperature, and can also improve the power factor and power quality of the equipment. The device is suitable for current and high-speed signal interference, low ripple, stable output, and fast response to sudden voltage changes, all of which are typically encountered in industrial applications. Besides, the device is suitable for LED driver noise protection and automotive application noise protection.

The basic working principle of the LGJ2G181MELC20 aluminum electrolytic capacitors is the same as that of ordinary capacitors. Electric charge is stored when current flows through the metal plates, that is, during the charging process. When the current stops flowing, the charged particles continue to remain on the metal plates, that is, during the discharge process. Due to the double electric plates of the aluminum electrolytic capacitor, some capacitors even produce voltages greater than 250V.

The alumina oxide resistant layer on the aluminum surfaces acts as an insulating diaphragm between the two electrodes. The main function of the insulating layer is to prevent the electrolyte from flowing onto the electrode, which could short-circuit or damage the capacitor. The dielectric of the aluminum electrolytic capacitor is formed by a very thin oxide layer on the surface of the aluminum foil. The applied voltage is a large enough force to pass electric charge through the oxide layer and create a electric field between the two metal plates.

The electrolyte of the LGJ2G181MELC20 aluminum electrolytic capacitor helps in transferring electric charges. This is mainly because the electrolyte is composed of molecules that can carry electric charges through them. This ensures a more efficient transfer of electric charges and more significant capacitance and breakdown voltage values.

In summary, the LGJ2G181MELC20 aluminum electrolytic capacitors are widely used in various electronic and electrical equipment due to its low profile, good temperature stability and long operating life. The working principle of the device is based on the electrical charge transfer between the two metal plates. The insulating dielectric provides the necessary insulation between the two electrodes and the electrolyte helps in the efficient transfer of electric charge.
