Introduction

Aluminum electrolytic capacitors (AECs) are widely used in industry today and are the most popular type of capacitors. AECs are composed of a metal container, an anode, cathode and dielectric. The AEC\'s have a wide range of applications due to their small size and high capacitance. The metal container of these capacitors is made of aluminum, hence the name aluminum electrolytic capacitor. The containers can be cylindrical, rectangular or elliptical. The anode is typically made of aluminum foil or metalized film and the dielectric is usually a liquid electrolyte or a solid electrolyte material. The size of AECs can vary greatly, ranging from very small components to large components.

UUJ0J472MRQ6ZD Application Field and Working Principle

UUJ0J472MRQ6ZD is a type of aluminum electrolytic capacitors specifically designed for automotive and industrial applications. UUJ0J472MRQ6ZD capacitors are designed to a maximum operating temperature of 125 degrees Celsius, which means that they can handle higher temperature applications without sacrificing their performance. UUJ0J472MRQ6ZD capacitors have a high capacitance, low equivalent series resistance (ESR) and low equivalent series inductance (ESL).The working principle of aluminum electrolytic capacitors is based on Faraday\'s Law of Electrolysis. This law states that when an electric voltage is applied to a solution, ions of a certain charge are attracted to the electrodes and the electric current starts to flow. As the electric current passes through the electrolyte, the anode changes form, releasing the ions, and forming a charge layer on the anode surface. The ions of opposite charge then move to the cathode and the total charge stored in the capacitor increases. This process of ionic movement and charge formation is what makes the aluminum electrolytic capacitor work.
