Aluminum - Polymer Capacitors

Aluminum - polymer capacitors (also known as a hybrid or aluminum electrolytic capacitor) are a type of electrolytic capacitor. They have a large amount of capacitance in a small size and are often used in space-limited applications. Their unique construction allows them to have higher operating temperature ratings and better electrical performance than other capacitors.

The EEF-LX0D561R4 application field is the direct current (D.C.) filtration, battery back up and snubbers. This applications is performed based on its working principle of storing and releasing energy.

Working Principle

Aluminum - polymer capacitors utilize two different electrical components in its construction. The first component is an aluminum can which contains aluminum nanoparticles and a polymer electrolyte. The second component is a thin plastic film which holds an electrolyte solution and serves as the capacitor’s dielectric.

The aluminum can contains a high concentration of ions, which act as charge carriers inside the capacitor, thus allowing it to store electrical energy. At the same time, the electrolyte solution inside the plastic film acts as an insulating barrier between the two plates of the capacitor. This insulating layer allows the capacitor to release energy at a controllable rate, as well as prevent energy leakage.

A capacitor’s capacitance is determined by its size, shape, and material composition. Aluminum - polymer capacitors are capable of offering a much higher capacitance than other types of electrolytic capacitors due to their unique construction. This makes them especially useful in applications that require a high capacitance and/or quick response time.

Benefits of Aluminum – Polymer Capacitors

Aluminum - polymer capacitors offer a number of benefits versus traditional aluminum electrolytic capacitors. Unlike aluminum electrolytic capacitors, aluminum - polymer capacitors can be designed with extremely thin dielectric layers, meaning that the size of the capacitor can be greatly reduced. They also have higher operating temperatures and a longer useful lifespan than aluminum electrolytic capacitors.

Additionally, aluminum - polymer capacitors have a lower equivalent series resistance (ESR) than other electrolytic capacitors, resulting in higher power output ratings. Furthermore, these capacitors are self-healing and feature built-in temperature compensation, which helps to ensure a stable voltage output over a wide temperature range.

Conclusion

Aluminum – polymer capacitors are a highly efficient and reliable alternative to traditional electrolytic capacitors. With their high capacitance and thin form factor, they are a great choice for many applications that require quick response times and high power capabilities. The EEF-LX0D561R4 is a perfect example of this type of capacitor, and is well suited for the direct current (D.C.) filtration, battery back up and snubber applications it is designed for.
