Aluminum electrolytic capacitors are a type of common capacitor that relies on an oxide layer, a liquid electrolyte, and aluminum electrodes. They are used in applications that require high capacitance, high ripple current, and low equivalent series resistance (ESR). MAL213668689E3 is a type of aluminum electrolytic capacitor manufactured by the Japanese company Nichicon. In this article, we will discuss the application field and working principle of MAL213668689E3.

Introduction to MAL213668689E3

MAL213668689E3 is a cylindrical aluminum electrolytic capacitor with a nominal capacitance of 470 uF and a rated voltage of 25V. It has a maximum operating temperature of 105°C and a maximum ripple current of 4.2A. The capacitors are designed with a snap-in mounting for easy installation, and they are UL, VDE, and CSA recognized.

Application Field

Aluminum electrolytic capacitors are used in various applications where large energy storage is required. MAL213668689E3 is used mainly in car electronics such as power supplies, switch power supplies, inverters, and motor drives. It is also used in LED backlighting, audio applications, and vibration motors. In addition, it can be used for general power line filtering, motor start-up, and EMC countermeasures.

Working Principle

The working principle of aluminum electrolytic capacitors is based on Faraday’s Law of Electrolysis. This law states that when a charge is applied to an electrolyte, it breaks down into its component parts. In this case, the electrolyte is a liquid electrolyte made up of a solution of aluminum oxide and an ionic compound. The aluminum oxide forms a dielectric layer on the aluminum electrodes, allowing a charge to build up between them. When a voltage is applied, the electrons are attracted to the positive terminal of the capacitor, forming the electric field. The frequency response of the capacitor depends on the size of the dielectric layer and the ionic concentration in the electrolyte.
