Introduction

Aluminum electrolytic capacitors are the most commonly used type of electrolytic capacitor. These capacitors use a metalized aluminum foil as their electrodes, which is then rolled and inserted into an electrolyte-filled can. The LAQ2P271MELC20 is an aluminum electrolytic capacitor, specifically designed for high temperature applications up to 105°C.

Application Field

The LAQ2P271MELC20 aluminum electrolytic capacitor is used in a range of applications where high temperature performance up to 105°C is required. These applications include:

• Automotive Electronics: It has been used in fuel pumps, airbag systems, and engine control units.
• Industrial Electronics: It has been used in lighting systems, ventilation systems, and solar panel controls.
• Telecommunications: It has been used in base stations, cell phones, and antenna systems.
• Appliances: It has been used in refrigerators, washing machines, and dishwashers.
• Computers: It has been used in laptop motherboards, graphics cards, and other computer components.

Working Principle

An aluminum electrolytic capacitor functions by storing electrical energy in the form of an electrostatic field between its conducting plates. When voltage is applied to the capacitor, the plates acquire opposite electrical charges, which repel each other and create a potential difference between them. The capacitor is then able to store energy in the form of this potential difference.

When a current is passing through the capacitor, it is known as a ‘charging’ current, because it is transferring charge from one plate to another, thus creating a ‘charge’ on the capacitor. When the current flow is reversed, as it is when the capacitor is in use, it is known as an ‘in-rush’ current and is responsible for the capacitor discharging its stored energy.

The LAQ2P271MELC20 aluminum electrolytic capacitor is constructed with a metalized aluminum foil background with an anode layer of manganese dioxide and a cathode layer of aluminum. This combination of layers provides excellent performance at high temperatures, along with a long life expectancy.

Conclusion

The LAQ2P271MELC20 aluminum electrolytic capacitor is designed for use in a wide range of high temperature applications. Its construction with a metalized aluminum foil background and layers of manganese dioxide and aluminum provides excellent performance and long life expectancy. The capacitor functions by storing electrical energy in the form of an electrostatic field between its conducting plates.
