Aluminum Electrolytic Capacitors: MAL202190589E3 Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are special types of capacitors that use an aluminum electrolyte as their dielectric and have a large capacitance per unit volume compared to other types of capacitors. One of the most popular and widely used aluminum electrolytic capacitors is the MAL202190589E3. It is an axial-leaded capacitor with a capacitance of 1000uF, rated voltage of 250v, and an operating temperature range of -40 to +105 degrees Celsius. This article will discuss the application field and working principle of the MAL202190589E3.

Application Field of the MAL202190589E3

The MAL202190589E3 is mainly used in high voltage power supplies, DC-DC converters, and general power supply circuits. It is also often used in audio frequency power amplifiers to filter the AC ripple caused by the power supply. With its high capacity, low equivalent series resistance, fast response, and extensive operating temperature range, the MAL202190589E3 is perfect for use in these applications.

Working Principle of the MAL202190589E3

The working principle of the MAL202190589E3 is similar to all aluminum electrolytic capacitors. It contains a thin layer of aluminum oxide that acts as an insulator and a layer of electrolyte liquid, usually formed of boric acid or water-based solution, that serves as the capacitive medium. When a DC voltage is applied to the capacitor, the negative side of the capacitor attracts positively charged ions from the electrolyte while the positive side attracts negatively charged ions from the electrolyte. This results in an electrostatic field within the capacitor allowing the capacitor to hold a charge. The actual capacitance is determined by the ratio of the area of the electrodes to the distance between them.

Advantages of the MAL202190589E3

The MAL202190589E3 has many advantages as compared to other types of aluminum electrolytic capacitors. It has a high capacity compared to other types of electrolytic capacitors and it also has low equivalent series resistance. This makes it very suitable for use in high voltage power supplies and general power supply circuits. Additionally, its operating temperature range is higher than other aluminum electrolytic capacitors and it has a fast response time, making it perfect for use in audio frequency power amplifiers to filter out AC ripple noises.

Conclusion

The MAL202190589E3 is a popular and widely used aluminum electrolytic capacitor. It is mainly used in high voltage power supplies, DC-DC converters, and general power supply circuits as well as audio frequency power amplifiers.
