Aluminum - Polymer Capacitors

The 875075561006 aluminum-polymer capacitor is a member of the aluminum-polymer capacitor family and is designed for a variety of applications. In this article we will discuss the key features and working principles of 875075561006 aluminum-polymer capacitors.

Application Field

The 875075561006 is an aluminum-polymer capacitor which has the unique ability to store a significant amount of energy in a extremely small size with excellent electrical performance. It has an excellent ripple current capability, noise suppression capability and higher long term reliability, making it usable in demanding high power applications such as automotive and industrial use. It is ideal for use in situations where large and heavy capacitors are not feasible, such as in high-frequency inverters, switching power supplies and electric motor drive systems.

Working Principle

The 875075561006 aluminum-polymer capacitor is a combination of both an aluminum electrolytic capacitor and a film capacitor. The aluminum-polymer capacitor has a very simple working principle. It consists of a combination of a porous aluminum foil, which has been passivated, and a solid polymer dielectric between two metal alloy electrodes.

When a voltage is applied, the metal alloy electrodes ionize and form a solid electrolyte film. This film gives the 875075561006 aluminum-polymer capacitor the ability to store electrical energy in a significantly smaller form than an aluminum electrolytic capacitor.

The dielectric used in a 875075561006 aluminum-polymer capacitor is also quite unique. It can be made up of a variety of polymers, such as polyethylene, polystyrene and polypropylene. The dielectric can also be custom designed to provide extra stability and high temperature resistance in order to make the capacitor suitable for high temperature applications.

Advantages and Drawbacks

The 875075561006 aluminum-polymer capacitor offers many advantages in a range of power applications. One of the key benefits of this type of capacitor is its relatively small size and physical ruggedness. This makes it much more suitable than its aluminum electrolytic equivalent in applications where vibration and shock are common, such as automotive and industrial use.

The 875075561006 also offers impressive ripple current and noise suppression capabilities, which makes it suitable for high power applications. It also offers a much longer life cycle than its aluminum electrolytic equivalent, making it ideal for high-temperature and high-cycle applications.

The drawbacks of the 875075561006 aluminum-polymer capacitor mainly relate to its higher price tag compared to standard aluminum electrolytic capacitors. This is due to the relatively expensive process involved in manufacturing the aluminum-polymer capacitor. The higher price tag also applies to the custom designed dielectrics which can be used to add further stability and improved performance.

Conclusion

The 875075561006 aluminum-polymer capacitor is an attractive solution for applications where a smaller capacitor is desirable, such as in high-frequency inverters, power supplies and motor drive systems. It offers superior electrical performance in terms of ripple current and noise suppression, as well as offering a much longer life cycle than its aluminum electrolytic equivalent capacitor.

Despite its relatively higher cost, the 875075561006 aluminum-polymer capacitor offers the potential to save money in the long term due to its improved performance and longer life. This makes it an attractive option for applications where stability and reliability are paramount.
