Working Principle

The LNY2W821MSEFBN aluminum electrolytic capacitors work on the principle of electrolysis. They are composed of a thin layer of aluminum foil sandwiched between two layers of special dielectric electrolytic material (often referred to as ‘inner’ and ‘outer’ solution). When an electrical current is applied to the capacitor, it causes the aluminum foil to dissolve in the electrolyte, creating a solution of positively charged aluminum ions. These ions are attracted to the inner layer of the capacitor, where they combine with electrons to form an electrical field. The electrical field between the two layers creates a voltage drop across the capacitor, which is used to store electrical energy. The amount of energy stored in the capacitor is directly related to the size of the voltage drop – the larger the voltage drop, the higher the amount of energy stored.Moreover, due to the low impedance of aluminum foil, the electrical current passes through the capacitor with minimal resistance, allowing for quick discharge and response times.

Conclusion

The LNY2W821MSEFBN aluminum electrolytic capacitor is a versatile and cost-effective solution for a wide range of applications. Its low-cost and small size make it ideal for use in a variety of industrial, medical, and consumer electronics. It is designed to provide reliable and stable performance in all types of high-power and energy-intensive applications. The capacitor works on the principle of electrolysis, allowing it to quickly store and discharge energy with minimal resistance.
