Aluminum Electrolytic Capacitors: SK220M100ST Application Field and Working Principle

Aluminum electrolytic capacitors, also called aluminum electrolytics, are a polarized type of capacitor whose anode-electrolyte system is anodized aluminum. They have a large working voltage range and a wide temperature range, making them a popular choice for many different applications. The SK220M100ST is a radial leaded aluminum electrolytic capacitor ideal for applications requiring high dielectric strength, very high ripple current, long life and reliability. In this article, we will explore the application field and working principle of the SK220M100ST aluminum electrolytic capacitor.

Working Principle of the SK220M100ST

The SK220M100ST aluminum electrolytic capacitor is constructed with an anode composed of anodized aluminum, a cathode composed of a non-conductive polymer, and an electrolytic solution mixed with a potassium hydroxide or acetic acid. The anodized aluminum acts as the dielectric, allowing for an increased range of electrical charge acceptance. When electricity is applied, the anode transfer electrons to the other side, forming a polarized electric field. This electric field is what stores energy, and allows for the capacitor to be functional.

The SK220M100ST also features a balanced internal construction, which allows for very low ESR (Equivalent Series Resistance), as well as low ESL (Equivalent Series Inductance). This ensures optimal performance in high ripple current applications. The SK220M100ST also has a very long life expectancy, allowing for up to 2,500 hours of life at its rated temperature of 105°C.

Applications of the SK220M100ST

The SK220M100ST is ideal for applications requiring high ripple current and long life. As a general purpose aluminum electrolytic capacitor, it is most commonly used as a filter, or as a power supply electrolytic in AC/DC power supplies, UPS systems, portable audio equipment and other consumer electronics.

In automotive applications, the SK220M100ST can be used in ECUs (Electronic Control Units), energy storage modules, and DC/DC converters. In the medical industry, SK220M100STs can be used in instrumentation for monitoring, control, and external device operation.

Due to its high level of performance and long life expectancy, the SK220M100ST is also an ideal choice for solar power system management, power amplifiers, DC/DC conversion, and many other professional electric applications.

Conclusion

The SK220M100ST is an ideal aluminum electrolytic capacitor for applications requiring high ripple current and long life. Its polarized electric field makes it more efficient than other types of capacitors, allowing for a greater range of electrical charge acceptance. Additionally, its high performance and long life expectancy make it a popular choice for many different applications, from consumer electronics to automotive and medical equipment.
