Aluminum electrolytic capacitors are widely used in a vast range of electronics. One popular type of capacitor in this family is the MAL213664472E3. This capacitor is specialized for high capacitance, low voltage, and long life applications. This guide will provide an overview of the MAL213664472E3\'s application field and working principle.

Application Field

The MAL213664472E3 aluminum electrolytic capacitor is recommended for use in applications that require long life and high capacitance, such as DC-DC converters, switching power supplies, and motor drives. Due to its excellent capacitance endurance and temperature characteristics, it is also suitable for high capacitance requirements in computers, automotive products, and other industrial applications where long lifetime and high capacitance are critical.

The MAL213664472E3 is ideal for use in circuits where polarized capacitors are not desirable. It can operate in temperatures between -40°C and +105°C, and is rated for a lifespan of more than 6,000 hours. Additionally, this capacitor features an integrated overpressure protection to prevent damage in cases of overvoltage or overcurrent.

Working Principle

The MAL213664472E3 is an aluminum electrolytic capacitor, which is based on the ability of an electrolyte to store electrical charge in two plates. The capacitor consists of three parts: two aluminum plates, which act as the cathode and anode, and a dielectric material, the electrolyte, which lies between them. The two aluminum plates are connected to the leads and when AC power is applied to the leads, the electrolyte is charged by ions, creating a capacitance between the two plates. Therefore, the capacitance of the capacitor is determined by the size of the plates and the electrolyte\'s ability to store electrical charge.

The MAL213664472E3 capacitor is a non-polarized aluminum electrolytic capacitor. It has a copper base foil which serves as an anode while the resulting electrolyte bearing the charge remains relatively thin. In this type of capacitor, two anodized aluminum foils are used. One of the foils serves as the anode while the other acts as the cathode. The two foils are separated by a thin film of electrolyte which stores the charge produced by the capacitor, and the anode and cathode are connected to the leads to provide a circuit.

The capacitance of the MAL213664472E3 aluminum electrolytic capacitor is determined by the size of the plates, the distance between the two plates, and the electrolyte\'s ability to store electric charge. The higher the capacitance, the more charge the electrolyte can store and the greater the amount of energy it can keep stored. Therefore, this type of capacitor offers high capacitance and long life.

In conclusion, the MAL213664472E3 aluminum electrolytic capacitor is an ideal choice for high capacitance, long life applications due to its excellent temperature, voltage, and capacitance characteristics. Its working principle is based on the ability of an electrolyte to store electrical charge in two plates. It is recommended for use in DC-DC converters, switching power supplies, and motor drives, as well as in high capacitance requirements in computers, automotive products, and other industrial applications.
