Aluminum Electrolytic Capacitors

Introduction

Aluminum electrolytic capacitors or aluminum electrolytic capacitors are electrical components that store electrical energy in an electric field. They are often used to filter or decouple signals and are incorporated in many end-use electronic devices such as amplifiers, computers, TVs, and amplifiers. As such, capacitors are some of the most widely used electronic components in the world.

381LX101M400J012 Overview

The 381LX101M400J012 is a classic aluminum electrolytic capacitor. It is a mid-sized, physically small capacitor that is both robust and reliable. It features a high temperature rating of up to 125°C, a low impedance of 0.1-0.2RΩ, and an operating life of up to 2,000 hours. It has a typical capacitance of 100μF and has an operating voltage of up to 400VDC. It is a throwback capacitor to classic days and is the perfect choice for any application where robust performance and a small physical size is needed.

Application Fields and Working Principle

Aluminum electrolytic capacitors, such as the 381LX101M400J012, are designed to store electrical energy in an electric field, temporarily providing extra power when needed. They are typically used to filter or decouple signals and are often a part of many electronic devices such as amplifiers and computers. As such, they are one of the most important electronic components in the world.

The working principle of aluminum electrolytic capacitors is fairly straightforward. First, an electrical charge is built up on an anode and a cathode separated by a dielectric base material, usually oxide aluminum. As the charge is built up, the electric field between these two plates produces an attractive force that causes a displacement current to travel across the dielectric material. As the current passes through the dielectric, it is stored as potential energy in the electric field and then can be released when needed.

The 381LX101M400J012 aluminum electrolytic capacitor is most often used in power supplies for audio and video equipment, medical analysis instruments, measurement devices, and data communications equipment. They are also often used in consumer electronics such as televisions, computers, and stereo amplifiers, as well as industrial applications such as arc welding machines and paper mills. Due to their robust, temperature-resistant build and low impedance, these capacitors are especially well-suited for environments where temperature variations and wide frequency ranges are present.

Conclusion

The 381LX101M400J012 aluminum electrolytic capacitor is a mid-sized, reliable, and robust component that offers improved functionality and performance when compared to traditional components. It features a high temperature rating of up to 125°C, a low impedance of 0.1-0.2RΩ, and an operating life of up to 2,000 hours. It is most often used in power supplies, consumer electronics, and industrial applications, and thanks to its temperature-resistant build and low impedance, it can handle varying temperatures and wide frequency ranges. All in all, the 381LX101M400J012 is an excellent choice for any application that requires robust performance in a small physical size.
