Introduction to Aluminum Electrolytic Capacitors

Electrolytic capacitors are one of the basic components used in various electrical and electronic equipment, and they are "electrochemical type" capacitors. It has a very large capacitance, which is formed by using a metal film as the positive electrode and using the principle of electrolysis to form an oxide film on the surface of the metal film (anode) and aluminum foil (cathode). Among the various capacitors, the aluminum electrolytic capacitor series (LLG2G471MELC30) has the characteristics of working performance, reliability, and cost performance.

Characteristics of Aluminum Electrolytic Capacitors

The aluminum electrolytic capacitor is based on the physical characteristics of aluminum, which has a large relative dielectric constant of between 8 and 16, and since the aluminum electrolytic capacitor uses aluminum foil as the anode, it has a large charge and a small volume. It has high capacitance and low loss, and is mainly used for energy storage, dc-dc conversion, noise filtering and decoupling.

LLG2G471MELC30 Application Field and Working Principle

The LLG2G471MELC30 aluminum electrolytic capacitors is mainly used in power supply, radio frequency electronics, aerospace, telecommunication, automotive electronics field, etc. In terms of radiation, as the LLG2G471MELC30 aluminum electrolytic capacitor releases a large amount of acrylamide, it is not suitable for the field with high radiation, such as medical equipment.The working principle of aluminum electrolytic capacitors is relatively simple. It consists of three parts: a positive electrode (anode) made of aluminum foil, a negative electrode (cathode) made of aluminum foil, and an electrolyte (dielectric). When the cathode and the anode are connected to the positive and negative poles of a DC power supply, the aluminum foil of the positive electrode will form an oxide film on its surface due to anodic reaction, thus forming a capacitor. And the electrolyte forms a electrical field with aluminum oxide film for charge storage. The larger the electrode area and the thicker the oxide film, the higher the capacitance of the capacitor.

Conclusion

In conclusion, the aluminum electrolytic capacitor is a type of electrolytic capacitors. It has a large capacitance and a small volume. It is mainly used for energy storage, dc-dc conversion, noise filtering and decoupling. The LLG2G471MELC30 aluminum electrolytic capacitor series has the characteristics of working performance, reliability, and cost performance, and it is mainly used in power supply, radio frequency electronics, aerospace, telecommunication, automotive electronics field, etc.
