Aluminum Electrolytic Capacitor: EKMQ350VSN103MR25S Application Field and Working Principle

An aluminum electrolytic capacitor is an electronic component that consists of two metal plates separated by a separator that has been soaked with an electrolyte liquid. One of the plates is usually made of aluminum foil that is etched with a figurative pattern to provide additional surface area. The other plate is usually made of a thicker metal that does not allow the electrolyte to flow through it easily. This type of capacitor is used in high voltage, high current applications, where the large capacity and low equivalent series resistance (ESR) of an aluminum electrolytic capacitor is needed.

EKMQ350VSN103MR25S Application Field

The EKMQ350VSN103MR25S aluminum electrolytic capacitor is specifically designed for power electronics applications. It offers an operating voltage range of 350V and a ripple current of 103mA per 25 seconds. This aluminum electrolytic capacitor can be used in pulse forming networks (PFN), voltage dividers, and other voltage-sensitive applications. This type of capacitor is often used in automotive, industry, and consumer applications to provide clean, stable power.

EKMQ350VSN103MR25S Working Principle

The EKMQ350VSN103MR25S aluminum electrolytic capacitor works by storing electric charge in an electrolyte solution between its two metal plates. When a voltage is applied across the electrodes, the electrolyte solution will conduct electric current through its particles, enabling it to store a certain amount of energy in the form of positive and negative charges. The positive charges will be attracted to the negative electrode and the negative charges will be attracted to the positive electrode, forming an electrochemical bridge. This bridge allows the capacitor to store and release energy as needed.

The electrolyte solution must be carefully weighed and added into the capacitor to ensure that the capacitor works correctly. In most cases, the capacitor is configured in such a way that it only allows current to flow in one direction. This ensures that the capacitor can store and release energy in a predetermined way.

The capacitance of the aluminum electrolytic capacitor is determined by the surface area between the two metal plates that are soaked with the electrolyte solution. The larger the surface area, the greater the capacitance of the capacitor will be. The amount of voltage that the capacitor is able to store is determined by the type of electrolyte solution that is used. Different types of electrolyte solutions have different effects on the voltage that can be stored.

Summary

The EKMQ350VSN103MR25S aluminum electrolytic capacitor is designed for power electronics applications. It offers an operating voltage range of 350V and a ripple current of 103mA per 25 seconds. This type of capacitor is used in automotive, industry, and consumer applications to provide clean, stable power. The working principle behind this capacitor involves storing electric charge in an electrolyte solution between two metal plates. The capacitance and voltage of the aluminum electrolytic capacitor are determined by the surface area between the two metal plates and the type of electrolyte solution used.
