Aluminum Electrolytic Capacitors: ULR2E220MNL1GS Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in various fields, such as DC power supply circuit, bypass, sample and hold, anti-interference, high-frequency coupling, electronic tuning and timing circuits. ULR2E220MNL1GS is a representative product of aluminum electrolytic capacitors. This article will discuss its application field, working principle and other related aspects.

Application Field of ULR2E220MNL1GS

ULR2E220MNL1GS is suitable for applications that require small size and long working life. This product is especially favorable for electronic control circuits of automotive electronic systems. Its wide temperature range – (-55~125°C) is well enough for long-term working even under extreme temperature changes. Its high vibration and shock resistance reduces the chances of damage from mechanical vibration and accidental shock.

ULR2E220MNL1GS also exhibits superior endurance to ripple current, making it suitable for applications with high AC ripple current, like adjustable DC power supplies. Its transient energy absorption performance further enhances its ripple current capability and makes it very durable in dynamic load situations. Besides, ULR2E220MNL1GS also features a good dynamic characteristic, which makes it suitable for frequency tuning and filtering in high-speed signal transmission applications.

Working Principle of ULR2E220MNL1GS

The basic structure of ULR2E220MNL1GS is a combination of a dielectric film and an electrolyte. The dielectric film is composed of porous aluminum oxide/conductive paste/metallic electrode three layers structure. This structure provides good insulation between the two electrodes and enhances overall capacity. On the other hand, the electrolyte is composed of organic solvents and electrolytes, which can form a wet sticky film on the porous layer of the dielectric film, allowing the electrons to flow between the two electrodes. Therefore, ULR2E220MNL1GS is able to endure high temperature, high shock and high ripple current.

The working principle of ULR2E220MNL1GS is simple, yet it provides reliable performance with high quality. During the formation of the dielectric film, the electric double layer formed between the two electrodes of the capacitor is enhanced by the electrolyte, which results in an increased capacitance. Also, the absorbed electrolyte greatly improves the ripple current capability of the capacitor. In addition, the utilization of conductive paste in the dielectric film provides low ESR values, which further enhances the performance of the capacitor.

Conclusion

ULR2E220MNL1GS is an aluminum electrolytic capacitor that features small size, long working life and excellent performance. It has wide application in DC power supply circuits, bypass, sample and hold, anti-interference, high-frequency coupling, electronic tuning and timing circuits. The working principle of ULR2E220MNL1GS involves a combination of a dielectric film and an electrolyte, which provides the capacitor its excellent performance while it works in extreme temperature, vibration and shock conditions. Therefore, ULR2E220MNL1GS is the ideal choice for all kinds of applications.
