Aluminum electrolytic capacitors are passive electronic components that use an electrolyte to store electric charge and are used to filter, decouple, and even store energy. The MAL212835229E3 is an example of a specific type of aluminum electrolytic capacitor, designed to have many features including low electrical resistance and a long lifetime. This article will discuss the application field and working principle of this type of capacitor.

Application Field

The MAL212835229E3 is a miniature aluminum electrolytic capacitor, specifically designed for use in noise suppression and low-pass filtering applications. This type of capacitors have a long life of up to 2000 hours and a very low ESR. It also has superior electrical characteristics such as good temperature and frequency characteristics. Due to its small size, it can be used for a variety of applications, including audio equipment, medical equipment, telecommunications, and industrial equipment. It can also be used as part of a larger system, such as motor drives, where it can provide power smoothing and filtering.

Working Principle

Aluminum electrolytic capacitors are based on an electrolytic chemical reaction between two electrodes, one being an anode and the other a cathode, and a third electrolyte. The electrolyte used in this type of capacitor is usually a liquid, typically a borax salt solution. When a voltage is applied, ions in the borax solution move to the anode, resulting in a deposit of aluminum oxide. This deposit functions as an insulator between the two electrodes, allowing the capacitor to hold the charge.

The MAL212835229E3, in particular, takes advantage of this principle by using rolled anodes made from aluminum foil. This structure provides for high surface areas and extremely low ESR values, allowing for better performance and longer life times. This type of capacitor also utilizes solid electrolyte instead of liquid. The solid electrolyte consists of a material that is semi-conductive and insulating at the same time, making for a capacitor that is more stable and has more reliable performance.

The MAL212835229E3 has a variety of applications. It can be used as a power supply filter, noise suppressor, or low-pass filter. Its low ESR and long lifetime makes it ideal for these types of applications. It can also be used as a voltage reservoir in pulse-power type systems. In these applications, the capacitor can be used to absorb large amounts of energy that the system needs, and then discharge this energy in a controlled manner.

In summary, the MAL212835229E3 is an aluminum electrolytic capacitor designed for use in noise suppression and low-pass filtering applications. It utilizes rolled anodes made from aluminum foil and solid electrolyte for increased stability and reliable performance. This type of capacitor has a long life of up to 2000 hours and a very low ESR. Its low ESR and long lifetime make it ideal for applications such as power supply filters, noise suppressors, low-pass filters, and voltage reservoirs in pulse-power type systems.
