Aluminum - Polymer Capacitors

Aluminum-polymer capacitors are a type of electrical component used for a variety of applications. They are similar to aluminum electrolytic capacitors, but have different construction and working principle. They are commonly used in dc-dc converters, portable device chargers, and as a power filter. This article will explain the application fields and working principle of the 875115852001 aluminum-polymer capacitor.

Application fields

The 875115852001 aluminum-polymer capacitors are mainly used in the power converter and filter segment. They are especially suited for applications that require rapid change in ripple current, such as switching mode power supplies (SMPS). They can also be used in other power applications, such as inverters and noise suppression circuits. Furthermore, they are suitable for high-frequency applications since they exhibit low equivalent series resistance (ESR) at high frequencies.

Working principle

The 875115852001 aluminum-polymer capacitor consists of two conductive plates made from aluminum and a dielectric material. When an electric field is applied, a polarized electric field is created by the aluminum layer. This polarized field helps to create a strong electric field for the capacitor, which helps to increase its capacitance. To further increase the capacitance and stability of the aluminum-polymer capacitor, a polymer material is added between the aluminum layers. This helps to improve the spacing and conductivity of the aluminum layers and increase the capacitance.

The 875115852001 aluminum-polymer capacitors also feature internal capacitance stabilization, allowing them to maintain a constant capacitance even when subjected to high temperature or frequency fluctuations. This allows them to be used in places where stability is required, such as power supplies.

Conclusion

The 875115852001 aluminum-polymer capacitors are a type of capacitor suited for applications requiring high levels of stability and rapid changes in ripple current. They are mainly used in power converters, filters, and noise suppression circuits. This article explained their application fields and working principle.
