Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are essential components used in an array of electronic equipment and devices, especially those used in computer systems, radios, audio devices, and power supplies for electronic circuits. They are further divided into three main types, the axial lead type, the snap-in type, and the SMD (surface mount) type. A notable feature of many aluminum electrolytic capacitors is their large capacitance in a very small and light weight form factor. This makes them well suited for high frequency circuits and other designs requiring a two-terminal element with high capacitance.

LNY2W822MSEJBB Application Field and Working Principle

The LNY2W822MSEJBB is an SMD aluminum electrolytic capacitor manufactured by AXiCap Inc., and is used in portable electronics, such as notebook computers, mobile phones, and tablets. The capacitor is rated for a capacitance of 820 µF, a voltage rating of 25 VDC, and a temperature range of -25 to +85°C. The LNY2W822MSEJBB is constructed using a radial mount with two cathode leads.An aluminum electrolytic capacitor works on the principle of electrolysis. One of the leads is made of aluminum foil, while the other is made of a gauze, which is soaked in an electrolyte solution. The electrolyte acts both as an insulator and as an ionizer. When a voltage is applied across the leads, the electrolyte allows electrons to flow through the medium, thus creating orthogonally arranged electric fields. These electric fields generate Faradays law of induction, which creates a static electrical field that opposes the movement of charges, and thus, results in an increase in the capacitance.

LNY2W822MSEJBB Characteristics

The main characteristics of the LNY2W822MSEJBB are its high capacitance density, low-ESR (Equivalent Series Resistance), high ripple current rating, and long life expectancy. The large capacitance of 820 µF enables the capacitor to store a relatively large charge, making it suitable for use in high power electronic devices, such as notebook computers and tablets. Its low ESR ensures efficient charging and discharging of the capacitor, which results in reduced heat dissipation and less power dissipation. The high ripple current rating of the capacitor means that it can deliver reliable power to the connected circuit, without any significant voltage drop. Lastly, the long life expectancy of the LNY2W822MSEJBB, which is rated at 10,000 hours, ensures that the device’s performance can be relied upon for a long period of time.

Conclusion

The LNY2W822MSEJBB is a versatile, high-performance aluminum electrolytic capacitor, used in many portable electronic devices. Its high capacitance density, low-ESR, high ripple current rating, and long life expectancy make it an ideal choice for applications such as notebook computers, mobile phones, and tablets. It is a reliable and efficient capacitor, designed to provide exceptional performance for a long period of time.
