Aluminum electrolytic capacitors, or aluminium electrolytic capacitors, are a capacitor constructed with an anode of aluminum foil covered with an insulating oxide layer, the cathode of a metal or alloy foil, and an electrolyte of liquid or gel, enclosed in a cylindrical, oval, or rectangular metal or plastic case. The MAL202139108E3 is an aluminum electrolytic capacitor from Coilcraft, with rated voltage of 63 VDC, tolerance of 20% and capacitance of 4700 uF. This capacitor is particularly designed for high-temperature, high-performance filtering applications.

Electrical energy consists of two basic components, power and capacitance. Power is the amount of energy per unit of time, and capacitance is the amount of energy stored in an electric field. And capacitance is essentially the electrical equivalent of a storage tank for energy. And with a capacitor, this energy is literally stored in an electric field, the electric field between two conductors. An equivalent electrical circuit can be formed with a capacitor and a specific type of voltage source, such as a battery. A capacitor essentially holds electrical energy in the form of an electric charge, within the gap between its two electrode plates.

The MAL202139108E3 consists of rolled aluminum foil with a thin oxide layer. It has three components, the positive and negative electrodes, and the electrolyte. The positive electrode is made of aluminum, the negative electrode is made of tin-plated steel and the electrolyte is a gel solution. This capacitor utilizes the electrical double-layer effect where the two charged electrodes form an electric field with the electrolyte. This results in a storage of energy and a consequent increase in capacitance.

The MAL202139108E3 has an excellent ability to protect against voltage peaks and is capable of providing long-term protection from disruptions in the power supply. This makes it especially useful in high-temperature and high-performance filtering applications. Its capability to resist high-frequency transient voltages and its low equivalent series resistance make it ideal for use in power conditioning and controlling circuits, such as power factor/harmonic correction and voltage sag and surge protection.

In addition, its aluminum foil construction makes it suitable for applications in the telecommunications and medical industries. With its rated voltage capacity of 63 VDC, it is suitable for applications in telecommunications equipment, medical devices, and in industrial systems that require decoupling of digital signal sources. The MAL202139108E3’s ability to store energy efficiently, and its ability to resist voltage peaks in high-frequency applications, make it a very valuable component for power conditioning and industrial signal filtering.

The MAL202139108E3 is a great example of how aluminum electrolytic capacitors are useful components in a wide variety of applications. With its aluminum foil construction and electrolyte, it is able to provide excellent high-temperature, high-performance filtering and power-conditioning capabilities. Its wide range of uses in telecommunications, medical, and industrial applications make it a great choice for those looking for reliable and durable components in their systems.
