Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in the field of electric, electronic and communication products and mechanical and electrical control systems. There are various models of aluminum electrolytic capacitors in the market, and different models have different capacitance and working voltage. One such type is the LGG2W181MELZ40.

The LGG2W181MELZ40 aluminum electrolytic capacitor is based on the non-solid electrolyte principle. It consists of two pieces of aluminum foil, two pieces of paper insulation materials, and two pieces of aluminum foil covered with a thin layer of electrolyte. There is a gas initiation explosion device at both ends of the capacitor, which is the sole difference from a standard electrolytic capacitor.

With its high capacitance, the LGG2W181MELZ40 is suitable for a wide range of applications, including power supplies and audio amplifiers. It can also be used as a general-purpose capacitor in AC frequency circuits, filters, and step-down circuits. Due to its large size, suitable for use in high-value power supply circuits, and very stable capacitance, this capacitor is often used in audio amplifiers, medical instrumentation and consumer electronics.

In terms of its working principle, the LGG2W181MELZ40 aluminum electrolytic capacitor has two poles, an anode and a cathode. The anode is roll coated with an oxide film, while the cathode is composed of paper and aluminum foil. As a result of an electrolytic process, the anode films produce a very high capacitance. When applying an electric charge to the two poles of the capacitor, the anode film will deposit an electrical charge on the aluminum foil and the electrons will be stored on the surface of the cathode paper, forming a dielectric layer. This dielectric layer increases the capacitance of the capacitor, resulting in the storage of a large amount of charge and creating the electric field necessary for the capacitor to store and discharge energy.

In conclusion, the LGG2W181MELZ40 aluminum electrolytic capacitor is an excellent choice for a wide range of applications from power supplies to medical instruments. Its high capacitance and low leakage current make it suitable for even the most demanding applications and its large size makes it perfect for use in high-value power supply circuits. Moreover, its stable capacitance makes it ideal for audio amplifiers.
