Film Capacitors are an important component of electronic circuits, and theR46KN415040P1M is a typical type of film capacitor. It is characterized by small size, low temperature drift, low self-induction, long working life, and high accuracy. This article shall discuss its application field, as well as its working principle.

Application Field

The R46KN415040P1M is mainly used in agriculture, automobiles, communications, inverters, military, and other industries and applications. It is most often used in temperature monitoring systems, electrical systems, and low-voltage pulse circuits. Specifically, in the temperature monitoring system, it can be used to detect temperature in pipelines, bearings, transformers, motors, and other locations. In the electrical system, it is often used as a condenser element, a coupling capacitor, or a bypass capacitor. In the low-voltage pulse circuit, it can reduce the pressure and eliminate noise in the high-frequency pulse circuit.

Working Principle

The R46KN415040P1M is a film capacitor with a solid dielectric. Its principle of work involves the internal material of the capacitor forming a dielectric layer, and storing electric energy by creating an electric field. This is essentially the same mechanism employed by air capacitors or ceramic capacitors. Its working principle can be further divided into the following two aspects.

Static Working Principle

In the case of the R46KN415040P1M, its static working principle involves using a single-layer dielectric film with a certain insulation resistance. The film is placed between the two electrodes, resulting in the formation of an electric field between them. This ensures that when voltage is applied between the two electrodes, the electric field generated allows for the capacitor to store electric energy on its dielectric film. Through this mechanism, the capacitance of the film is determined by its material, thickness, area, and voltage. In this case, its capacitance is R46KN415040P1M.

Dynamic Working Principle

Existing in parallel with the static working principle of the R46KN415040P1M is the dynamic working principle. When voltage is applied to the capacitor, it works by using the electric field created to pass current through the dielectric material. This current can alternate between positive and negative, in accordance to external conditions. As such, the capacitor allows for AC voltage signals to pass, as previously mentioned. This is enabled as a consequence of two charges having the capacity to alternate between two of its terminals when voltage is applied.

Conclusion

In short, the R46KN415040P1M is a film capacitor and belongs to the Film Capacitors family. It has a variety of applications and is commonly used for temperature monitoring systems, electrical systems, and low-voltage pulse circuits. Its working principle can be divided into two aspects, namely the static and dynamic working principles. In the first, electric energy is stored and in the second, current can alternately flow between the two terminals. As such, this ensures that the capacitor can pass AC voltage signals while adhering to the parameters mentioned earlier.
