Film Capacitors

Film capacitors, also known as film dielectric capacitors, are a type of electrical component which uses a dielectric material to store electrical energy. They have been commonly used as signal processing elements, filters, and in the control circuits of electronic equipment. The B81130B1474M series of film capacitors are specifically designed for medium and high frequency applications and are suitable for use in a variety of applications. This article will provide a brief overview of the B81130B1474M series and its application field and working principle.

Application Field

The B81130B1474M series are designed to be used in medium and high frequency applications such as filters, resonances circuits, and radio frequency (RF) applications. They are suitable for use in circuits which require high levels of stability, reliability, and low losses. Due to their median to high voltage rating, they are also suitable for applications in which high voltage levels are required. All of these features make them an ideal choice for circuits where reliability and efficiency are of the utmost importance.

Working Principle

At the heart of the B81130B1474M series lies its dielectric material, which consists of film with a suitable combination of polyester and polypropylene. This material is used to store energy in the form of an electric field between its two electrodes. When a voltage is applied across the electrodes of the capacitor, an electric field is created which causes the capacitor to store electrical energy. This energy can then be released as electric current or stored for future use.

The electric field between the electrodes is created by the dielectric material which has a dielectric constant, or k-factor, which determines the amount of energy that can be stored. The k-factor of the dielectric material depends on the type of material used, its thickness, and the temperature it is subjected to. As such, the performance of the capacitor will be affected by all of these factors.

In addition to this, the B81130B1474M series also has an insulation film which improves the performance of the film capacitor. This film helps to reduce the leakage current between the electrodes and prevents the voltage from fluctuating too much when the capacitor is subjected to temperature changes. This ensures that the device remains stable even under the harshest conditions.

Conclusion

The B81130B1474M series of film capacitors offer a number of key advantages such as high voltage ratings, low losses, and stability. They are suitable for use in a variety of applications where high levels of stability and reliability are required. Furthermore, their high dielectric constant and insulation film ensure that their performance remains stable under a wide range of conditions. As such, these film capacitors are ideal for use in any circuit or application where these factors are of importance.
