Aluminum electrolytic capacitors, also known as electrocaps and aluminium electrolytic caps, are passive components that offer high energy storage in a compact package. They are commonly used in electronic circuits, where their low impedance and large capacitance makes them ideal for AC power filtering and signal smoothing. In particular, the UPM1V820MED model of aluminum electrolytic capacitors are designed for general purpose use, and are one of the most popular types available. This article will discuss the application field and working principle of this capacitor.

Application Field

The UPM1V820MED aluminum electrolytic capacitor is commonly used in many different types of electronic circuits, due to its small size, high capacitance and low impedance characteristics. The most popular applications include power supplies and voltage regulators, where the capacitor can be used to reduce high frequency noise and to provide a stable output voltage. Additionally, the capacitor can be used as a power filter in automotive applications, providing a consistent power supply to critical components. Other applications include audio/video circuits, transmission/distribution networks, instrumentation, and electrochemical processes.

Working Principle

Aluminum electrolytic capacitors operate on a very simple principle. When a voltage is applied across the two electrodes, a current will flow due to an electric field inside the capacitor, charging it with electrical energy. The electric field itself is created by the separation of positive and negative ions (electrolytes). The electrolyte between the plates also serves to hold in a liquid that saturates the capacitor, allowing it to have a much higher capacitance than a solid capacitor of the same size.

When the capacitor is discharged, the oppositely charged ions move in the opposite direction and recombine, releasing the electric field and allowing the capacitor to discharge. This process can be repeated thousands of times without damaging the capacitor, making it ideal for applications that require repetitive charging and discharging such as filtering and signal smoothing.

Conclusion

The UPM1V820MED aluminum electrolytic capacitor is a popular and reliable choice for applications that require high capacitance and low impedance. Its small size makes it ideal for portable devices, and its low power consumption makes it an efficient choice for power filtering and voltage regulation. The simple principle behind its operation also guarantees a consistently high level of performance, making it suitable for a wide variety of kinds of applications.
