Aluminum - Polymer Capacitors

Aluminum - Polymer capacitors are a new type of high frequency capacitors that are used in many different applications, such as in telecommunications, aviation, automotive and consumer electronics. The PLF1E100MCL7TP is an example of such a capacitor, and its application field and working principle are as follows.

Application Field

The PLF1E100MCL7TP is designed primarily for use in high frequency power electronic applications and power applications. Its excellent capacitance retention properties make it a great choice for applications such as motor drives, DC-DC converters, inverters, and Class D amplifiers. Additionally, its low ESR, high ripple current capability, and high voltage rating make it a suitable choice for high frequency electromagnetic interference (EMI) and radio frequency interference (RFI) suppression.

Working Principle

The PLF1E100MCL7TP aluminum-Polymer capacitor operates on an electrochemical principle. Unlike conventional aluminum electrolytic capacitors, aluminum-Polymer capacitors are constructed with a solid dielectric layer instead of a liquid electrolyte. This solid dielectric layer is typically composed of Polymer or organic materials, such as Polyethylene napthalate or Polypropylene, which serves to maintain and improve the capacitance of the capacitor over time. The dielectric layer between the anode and the cathode also serves to reduce the ESR, which results in higher ripple current ratings.

The capacitance of the aluminum- Polymer capacitor can be adjusted and programmed by varying the thickness and type of the Polymer dielectric layer. This allows the capacitor to be customized for specific applications and for better control of ripple current ratings. Additionally, the capacitor can also be adjusted to provide suitable voltage ratings for a variety of applications. As a result, aluminum – Polymer capacitors have the advantage of providing higher capacitance than aluminum electrolytic capacitors while still maintaining a low ESR and low stray inductance.

Conclusion

The PLF1E100MCL7TP is a highly versatile aluminum- Polymer capacitor that is suitable for a wide range of applications. Its excellent capacitance retention properties and adjustable capacitance, ESR and voltage ratings allow for great customization for specific applications. Additionally, its low ESR, high ripple current capability, and high voltage rating make it a suitable choice for high frequency electromagnetic interference (EMI) and radio frequency interference (RFI) suppression.
