Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used type of capacitor available in the consumer electronics world. They are composed of two metal plates separated by a thin membrane of an electrolyte and connected to two terminals. These capacitors offer a wide range of capacitances, low impedance, low dissipation factor, high temperature stability, and long-term reliability.

MAL213658821E3 is a very popular type of aluminum electrolytic capacitor. It has a working voltage of 50V and a capacitance of 47µF. This capacitor is mainly used in automotive and industrial applications due to its high performance characteristics.

Application Field

MAL213658821E3 aluminum electrolytic capacitors are used in various applications, such as automotive, industrial, and consumer electronics. The capacitor is used in automotive ECUs to filter and smooth the current supply to the actuators and other components. It can also be used to reduce the noise of the induction motor as an ignition coil suppressor. In power supplies, the capacitor is used to filter ripple current as a SNUBber capacitor. The capacitor can also be used for filtering the high-frequency signals in consumer electronic products such as digital devices and audio equipment.

Working Principle

The capacitor consists of two metal plates separated by a thin membrane of an electrolyte and connected to two terminals. When a voltage is applied, an electric field is created between the two metallic plates and this is where the capacitance comes into play. The electric field attracts electrons, which are accumulated on the metal plates and an electrical charge is generated. The capacitance of the capacitor is determined by the amount of charge stored. When the charge reaches its maximum level, the flow of current stops, thereby stabilizing the voltage.

The size and shape of the capacitor determine the amount of charge stored, while the voltage determines the capacitance. The electrolyte membrane acts as an insulator, preventing any current from flowing between the metal plates even if they are charged. In this way, the capacitor can store charge for a long time without any leakage.

The aluminum electrolytic capacitor is reliable and stable with a long lifespan, making it ideal for use in many different applications. The capacitor is low impedance, low dissipation factor, and has a high temperature stability. The capacitor can also handle large capacitance values which is important in some applications such as in power electronics and LED drivers. Overall, the MAL213658821E3 aluminum electrolytic capacitor is a great choice for many different types of applications.
