This article will discuss the application field and working principle of the ELH687M400AT4AA.

Application Field

The ELH687M400AT4AA is primarily designed for use in power electronics applications, such as frequency converters, servo drives, and motor control. It is also suitable for applications with high performance requirements, such as DC / DC converters, adapters, and LED lighting. It is capable of handling current up to 300A and has a small size, allowing it to be used in compact designs. Due to its performance and size, it has become a popular choice for designers and engineers looking for an efficient and reliable power capacitor.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on the physical principle of capacitance. Capacitance is a property of a capacitor that stores electrical energy in an electric field. In an aluminum electrolytic capacitor, two aluminum foil electrodes are separated by ion-permeable separator paper or other insulator. The separator paper is soaked in an electrolyte liquid, which acts as an ion-conducting medium. When a voltage is applied across the electrodes, a voltage difference is created, which causes ions to move from one electrode to the other. This movement creates an electric field between the two electrodes, which stores the electrical energy. As the electric field increases, the capacitance increases, allowing the capacitor to store more electrical energy.

The ELH687M400AT4AA aluminum electrolytic capacitor is a special type of capacitor designed for power electronics applications. It is constructed of two aluminum foil electrodes and a dielectric layer sandwiched between the two. The dielectric layer is made of a metal oxide film, which has a higher breakdown voltage and an extended life-span than plain paper capacitors. This type of capacitor is temperature, humidity, and voltage-stable, which makes it suitable for use in long-term, high-voltage applications.
