Introduction of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components with a wide range of applications in the electronics industry. They are used in filters, power supplies, oscillators, and many other circuits. An aluminum electrolytic capacitor is an electric double-layer capacitor that uses an aluminum oxide film as the dielectric and utilizes an electrolyte solution to form two layers of electric charge that store energy. The main advantages of aluminum electrolytic capacitors are their high capacitance and high voltage rating.

LKS1J392MESY Application Field and Working Principle

The LKS1J392MESY is an aluminum electrolytic capacitor from the Radial Lead Series of Panasonic’s Capacitor portfolio. This capacitor features an electrolyte-filled aluminum case. The features of the capacitor include a snap-in installation, low impedance, no reverse voltage protection, a long life (up to 2,000 hours), and high reliability. It is an ideal choice for power-supply, filtering, and rectifying applications.The working principle of an aluminum electrolytic capacitor is relatively simple. When a voltage is applied to the capacitor\'s plates, an anodic process occurs on the inner electrode (anode) which leads to the formation of a surface film of aluminum oxide on the anode. Electrons from the anode are attracted toward the dielectric oxide layer and away from the anode, thus forming an insulating barrier between the two metal plates.The anodic corrosion of the anode causes an increase in the capacitance of the capacitor. The oxide film can withstand high levels of voltage and current, so the capacitor can act as an effective charge storage device. The capacitance depends on the area of the foil, the amount of electrode surface exposed to the electrolyte, the thickness of the dielectric oxide film, and the thickness of the electrolyte film.

Conclusion

In conclusion, the LKS1J392MESY aluminum electrolytic capacitor has a wide range of applications, and its working principle is that an anodic process occurs on the inner electrode which leads to the formation of a surface film of aluminum oxide on the anode, thus forming an insulating barrier between the two metal plates. This allows for effective charge storage and makes the aluminum electrolytic capacitor a valuable component in various electronics applications.
