Aluminum electrolytic capacitors are an essential component in many consumer electronics as well as other electrical products. The LGNW6391MELC35 is an aluminum electrolytic capacitor that can be used in a variety of applications, due to its high capacitance and low leakage current. This section will explore the application field and working principle of the LGNW6391MELC35.

Application Field

The LGNW6391MELC35 aluminum electrolytic capacitor has a wide range of uses due to its high capacitance and low leakage current. The capacitor can be used in various power supplies, filter circuits, stabilizers, and other types of equipment and electronic products. It is also suitable for use in computer motherboards and other types of higher-voltage circuit boards. In addition, its high capacitance and low leakage current make it suitable for use in audio and video equipment.

Working Principle

Aluminum electrolytic capacitors are based on Faraday\'s law of electrolysis, which states that the amount of a substance deposited or dissolved in an electrolyte is proportional to the amount of electricity passed through the electrolyte. The working principle of the LGNW6391MELC35 is similar to that of other aluminum electrolytic capacitors. It consists of two electrodes, one of which is covered with an porous oxide layer. When a voltage is applied to the capacitor, electrolyte ions move from one electrode to the other, forming a conductive film on the oxide layer. This film stores electrical energy, which is then released when the voltage is removed.

The aluminum electrolytic capacitor is made up of an anode, a cathode, a dielectric oxide layer, and an electrolyte. The anode is composed of an aluminum foil with a thin oxide layer. The oxide layer acts as the dielectric and provides excellent insulation. The electrolyte absorbs and holds the ions from the anode in order to create a conductive path between the two electrodes. The cathode is typically made of metal or carbon, and it acts as the connection between the devices.

When a voltage is applied to the capacitor, the anode generates an electric field and the electrolyte absorbs the ions, thereby creating a conductive path through the capacitor. The dielectric plays an important role in resisting the flow of electrons, thus serving as an insulating material. When the voltage reaches its rated level, the maximum amount of current can be passed through the capacitor, and the entire process is repeated each time the voltage is applied.
