Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, use aluminum foil as the anode and a special paper as the insulation layer. The cathode is formed by anodizing the aluminum foil and depositing manganese dioxide (MnO2) on it. Aluminum electrolytic capacitors have excellent heat resistance, high reliability, large capacitance, and low price but their shortcomings are high equivalent series resistance (ESR), longer replacement times, and low ripple current.

UPW2V101MRD Application Field and Working Principle:

The UPW2V101MRD is an aluminum electrolytic capacitor especially suitable for many types of miniature electronic equipment. Small size, wide capacitance range, high temperature endurance, and long life are some of the advantages of this capacitor. Additionally, it is resistant to corrosion and contamination from shock, dust and vibrations.In terms of its electrical characteristics, UPW2V101MRD has a very small temperature coefficient: it offers better stability and accuracy of capacitance over temperature compared to conventional aluminum electrolytic capacitors. Additionally, its low ESR resistance ensures a large ripple current/high frequency operation and high reliability.The working principle of UPW2V101MRD is fairly straightforward. The capacitor utilizes the interface between aluminum oxide and electrolyte to form a dielectric barrier. The oxide forms a semi-conductor between the aluminum and the electrolyte, while the electrolyte ensures the correct conduction of current. In order to maintain high efficiency, anode and cathode must be kept at ideal distance. The voltage across the capacitor causes an electric field in the gap between the electrodes, thus forming an inductive capacitance. The capacitance is determined by the area of the anode and cathode, as well as the distance between them.Apart from its excellent electrical characteristics, UPW2V101MRD also has many attractive features, such as a wide capacitance range from 0.05 to 68,000 µF, a life expectancy of 20000-40000 hours, ripple current ratings up to 4.55A, maximum operating temperatures up to 125°C, and low leakage current. This makes it suitable for a variety of applications, such as noise filters in AC/DC power supply, pulse power supplies and automotive electronics.

Conclusion

In conclusion, UPW2V101MRD are ideal aluminum electrolytic capacitors, especially suitable for many types of miniature electronic equipment. Its predictability, small size, wide range of capacitance, and excellent thermal stability make it the perfect choice for noise filter applications. Its wide capacitance range, long life expectancy, high ripple current ratings, and low leakage current make it superior to traditional aluminum electrolytic capacitors.
