1. Working Principle and Characteristics of Aluminum Capacitor Assemblies
Aluminum capacitors are capacitors that use aluminum as an electrolyte and conductive material. Compared with traditional tantalum capacitors, aluminum capacitors are not only lower in cost but also have higher capacitance density. Its core components include aluminum foil, aluminum oxide film, and electrolyte. Aluminum foil serves as the conductive plate of the capacitor, while aluminum oxide film acts as a dielectric and electrolyte enhances capacitance.

The main features of aluminum capacitor assemblies include:

High capacitance and small size: Compared with other types of capacitors, aluminum capacitors can provide higher capacitance in a smaller volume, suitable for compact circuit design.

High stability and reliability: Aluminum capacitors can maintain high stability under a wide range of operating temperature and voltage conditions, so they are widely used in high-tech fields.

Cost-effectiveness: Compared with other capacitor types (such as tantalum capacitors), aluminum capacitors have a lower cost and are suitable for mass production.
