Aluminum - Polymer Capacitors

Aluminum-Polymer Capacitors are a type of capacitor that combines the very best of aluminum electrolytic and wet tantalum technologies with the reliable qualities of polymers technology. As a result, they offer customers a wide range of advantages, including lower failure rates, higher dielectric strength, and wide capacitance range, lower ESR and self-healing characteristics. These characteristics make them ideal for a variety of industrial, automotive, military and personal computer applications.

EEF-CD0E820ER Application Field and Working Principle

The EEF-CD0E820ER is a type of aluminum-polymer capacitor specifically designed for the combination of an electrolytic and wet tantalum technologies with the reliable qualities of a polymer technology. This capacitor is suitable for a wide range of use cases, including military, aerospace, and personal computer applications. For its design, aluminum and organic liquid electrolytes (OLE) serve as its main material and the two electrodes are made of a metal oxide based film, which can provide an even higher breakdown voltage compared to pure aluminum.A typical aluminum-polymer capacitor consists of three main components, the dielectric layer, the electrodes and the case. Firstly, the dielectric layer is formed by depositing a thin layer of aluminum oxide (Al2O3) onto the metal electrodes. This layer acts as an insulating barrier, preventing the current from passing through it. Secondly, a thin layer of electrolyte is then added to the aluminum oxide layer, through which the electrons will move effortlessly. Finally, a short-circuit element is used to protect the capacitor from overvoltage and other potential damages.When it comes to the EEF-CD0E820ER application field and working principle, the capacitor has a capacity of 820µF, working voltage of 6.3V, ESR of 0.64mΩ and a maximum temperature range of -25°C to +105°C. The capacitor has a wide range of applications in different fields such as automotive, military and aerospace, due to its exceptionally reliable performance. Its design and construction is specially designed to make it resistant to high voltage, temperatures and also to allow self-healing of the capacitor. In addition, its small size and lightweight makes it ideal for use in demanding applications, such as computerized systems and measurement systems.
