Aluminum electrolytic capacitors, which are also known as wet electrolytic capacitors or simply electrolytic capacitors, are very common electronic components that are used for a variety of functions. The ELXM251VSN181MP25S is a type of aluminum electrolytic capacitor specifically designed for automotive and other industrial applications. In this article, we will discuss the application fields and working principle of the ELXM251VSN181MP25S.

Application Fields

The ELXM251VSN181MP25S is primarily used in automotive applications, such as the fuel injection system, engine management systems, power steering systems, and start-stop systems. It can also be used in industrial applications, such as defense systems, agriculture, energy management, and other applications that require long-term reliable performance.

Working Principle

An aluminum electrolytic capacitor consists of two aluminum plates that are separated by an electrolyte material. When a voltage is applied to the capacitor, the positively charged ions in the electrolyte material flow to the negative aluminum plate. This creates a static electric field between the two plates and sets up the capacitance. When the voltage is removed, the stored charge remains in the electrolyte material.

The ELXM251VSN181MP25S is designed to provide low equivalent series resistance (ESR) and low equivalent series inductance (ESL) in order to maximize the efficiency of the application it is used in. It is also designed to have a long life and reliable performance even in extreme temperature and vibration environments.

To ensure reliable performance in automotive applications, the ELXM251VSN181MP25S is designed with a robust temperature range (from -40°C to +85°C) and a high-thermal shock capability (up to 500uA). It is also designed with a low-voltage leakage and low-noise performance, as well as a superior vibration resistance. Additionally, it has an extended life-time, ranging from 8000h to 20000h, depending on the application.

In summary, the ELXM251VSN181MP25S is a high-performance aluminum electrolytic capacitor designed for automotive and industrial applications. It is designed to provide low ESR, low ESL, high-temperature operation, excellent vibration resistance, and a long life-time.
