Introduction

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are capacitors that use an electrolytic solution as the dielectric medium. They are mainly used in power electronics applications, and also to provide significant added value in enhanced signal capacity and filtering performance. The capacitor type referred to here is EDK226M100S9PAA, which is a high-temperature radial lead Aluminium Electrolytic Capacitor. The applications covered in this article are industrial, automotive and consumer applications, and the working principle is also provided.

Electrolytic Capacitor

An electrolytic capacitor is a polarized capacitor which uses an electrolyte to achieve a larger capacitance per unit volume than other types of capacitors. The breakdown voltage of electrolytic capacitors is much higher than that of film capacitors and ceramic capacitors. They are widely used in power supply circuits, medical equipment, automotive electronic products, etc., and are mainly used for energy storage, interference suppression, frequency compensation, etc. The EDK226M100S9PAA is a type of radial lead electrolytic capacitor, with a thin-film anode outer sleeve for better heat dissipation. Its products are mainly used in various fields with wide temperature range requirements, such as medical electronics, communication protectors, computers, high temperature requirements automotive products, and other harsh applications in the industrial environment. The features of this capacitor are as follows:

• High-temperature rated at 105℃;
• High-density design, allowing for high capacitance in a small package;
• Ripple current up to 16.7A;
• High endurance & reliability.

Application Field

Industry

The EDK226M100S9PAA capacitor is mainly used in industrial power supplies, such as medical equipment, power supplies for electronic measuring instruments, and power supplies for motor control systems. Because of its high temperature tolerance, it is also applicable in other industrial fields. Its high capacitance and endurance make it suitable for use in circulators, tubular reactors and other power regimes where large energy storage and a high level of reliability is required.

Automotive

The EDK226M100S9PAA is suitable for use in harsh automotive electronic products such as airbag control systems, starter controllers, engine control units and more. Its high temperature rating combined with its high ripple current make it well suited for direct connection to the power source. Its ability to perform under such conditions is essential in providing reliable and durable performance across a variety of applications.

Consumer

This capacitor is suitable for higher-end consumer electronic equipment such as television sets,high-end audio systems and home theater systems. Its high temperature rating and endurance is well suited for continuous operation in such scenarios, and the high capacitance allows for greater energy storage and ripple current handling.

Working Principle

An EDK226M100S9PAA electrolytic capacitor consists of two metal plates separated by a thin electrolyte layer. The anode of the capacitor is typically made from a thin-film of aluminum, and the cathode is an aluminum oxide layer formed on the surface of the anode. To create a charge, an electrical field is applied across the plate, which splits the hydrogen and oxygen in the electrolyte layer, thus creating a gap with positive and negative charges. This gap is filled with electrons which creates an electric field across the gap that produces an electrolysis effect, resulting in a current flow. This current is then stored in the electrolyte, which produces a charge on the capacitor plates. The EDK226M100S9PAA has an expanded anode surface which means the capacitor can store a greater amount of charge and therefore is able to handle higher ripple current. The thicker electrolyte layer also means that the capacitor can withstand higher temperatures than other types of capacitors, making it suitable for applications where high temperatures are encountered. This capacitor also has a longer life than other types, making it ideal for long-term power applications.

Conclusion

The EDK226M100S9PAA is a high-temperature radial lead aluminum electrolytic capacitor. Its main application fields are industrial, automotive and consumer electronics. Its features make it highly suitable for power applications with higher ripple currents and lower temperatures. Its working principle is based on electrolysis, allowing it to store the electrical charge on the electrolyte layer formed across the aluminum plates. The EDK226M100S9PAA is a reliable and durable choice for applications requiring high temperatures and high ripple current handling, and is suitable for a variety of applications.
