Aluminum Electrolytic Capacitors are widely used electrochemical components that store and provide electrical energy. The UUH1H221MNQ1MS is a typical example of such a device. This section will discuss the application field and working principle of this aluminum electrolytic capacitor.

Application Field

The UUH1H221MNQ1MS series is mainly used for power supply, signal filtering, and pulse charging applications. It is also suitable for oscillation and stereo applications due to its performance. The capacitor series operate over a wide temperature range, making it highly suitable for automotive applications such. Additionally, the series has a very low self-inductance, which enables its use in high-frequency switching devices. The series also offers a very low ESR value, due to which it can be used in power supply circuits, and it is also suitable for smoothing high-temperature charging and discharging.

Working Principle

Aluminum electrolytic capacitors use an electrolyte to increase the capacitance of a aluminum foil and foil-like anode plate electrodes. This is created by an anode and a cathode, when an electric voltage is applied the molecules of the electrolyte form an electric double layer with the electrodes at the opposite side of the capacitor. This electric double layer provides the high capacitance of the capacitors. It is also responsible for the dissipative energy loss in the capacitors.

The UUH1H221MNQ1MS capacitor series combines a large capacitance in a small volume to achieve efficient operation. This series contains a planar capacitance element which is formed by laminating aluminum foil and metallized foil on both sides of a strip made of Polyphenylene oxide and polyester film. This sets up the planar capacitor as an electrolytic capacitor together with the electrolyte, allowing the capacitor to operate at high frequency, and high temperature with low losses.

The construction of the capacitor series also allows for high capacitance and low impedance with minimal size and weight, making it ideal for mobile and computer applications. The capacitors are also available in lead-free and multiple terminal formats, providing further designs for different applications.

Conclusion

The UUH1H221MNQ1MS capacitor series is a very versatile aluminum electrolytic capacitor series. It provides a wide range of applications from power supply, signal filtering and pulse charging to oscillation and stereo applications. It also features a small size and low losses, making it suitable for high frequency switching devices, power supply circuits, and high-temperature charging and discharging. All in all, the UUH1H221MNQ1MS Aluminum Electrolytic Capacitor series is a reliable and cost-effective device for many applications.
