Aluminum Electrolytic Capacitors are an essential component in many electronic systems and machine controls. Commonly used for filtering and energy storage, these versatile components offer a range of features and applications. The ESG226M400AL4AA is one such component, widely used in automobiles and industrial applications, and this article explores its application field and working principle in more detail. Application Field
The ESG226M400AL4AA is a radial leaded aluminum electrolytic capacitor which offers a wide range of applications. It is primarily designed for applications which require a high capacitance density, such as in automobiles, where it is used for starting systems, lighting systems, and engine control systems. In industrial applications, it is typically used to store energy, filter noise, and stabilize voltage in areas such as automation and robotics. Working Principle
The ESG226M400AL4AA capacitor works through a process known as electrolytic action. This process is based on the principle of Faraday’s Law of Electrolysis, which states that when an electrical current is passed through an electrolyte, it will transport ions and electrons in opposite directions. The electrolyte in the case of the ESG226M400AL4AA is a combination of anodic and cathodic layers of aluminum oxide which is formed when an electric current is passed between two aluminum foils. As electricity is passed through the capacitor, the anode layer provides a positive charge, while the cathode layer is given a negative charge. The negative charge will cause an electrolyte to be deposited on the anodic layer, separating it from the cathode layer. This polymer layer serves as an insulation barrier, thereby creating an electrical field between the two layers and increasing the capacitor’s ability to store electrical charge.The ESG226M400AL4AA capacitor is also designed to provide a high temperature range of operations, with a temperature coefficient of -20ppm/K and an extended operating temperature range up to +130 degrees Celcius. This extended temperature range allows the capacitor to be used in a wider range of applications and environments, such as those which involve high temperatures or high levels of vibration. Conclusion
The ESG226M400AL4AA aluminum electrolytic capacitor is a versatile component which can be used in a wide range of applications. Its working principle is based on Faraday’s Law of Electrolysis, whereby an electrical current is passed through an electrolyte, creating an electrical field between the two layers and increasing the capacitor’s ability to store electrical charge. The capacitor is also designed to provide a high temperature range of operation, with a temperature coefficient of -20ppm/K and an extended operating temperature of +130 degrees Celcius.
