Film Capacitors

Capacitors are one of the most common components in electronic circuit, and film capacitors are a component of such capacitors. Film capacitors have advantages such as high insulation resistance, good heat resistance, high self-healing, and low dissipation factor, so they are widely used in many analog circuits, especially filters and audio circuits. One of the most popular film capacitors is MKP1837368164W. In this article, we will review the application field and working principle of the MKP1837368164W film capacitor.

Application Field of MKP1837368164W Film Capacitor

The MKP1837368164W film capacitor is a high power film capacitor, with a working voltage of 450vdc, a capacitance of 0.22μF, and a tolerance of 10%. Due to its high power and voltage rating, it is suitable for use in a variety of applications.For example, it is widely used in the design of DC filters, which require a high-power capacitor for filtering out AC ripple. In addition, the MKP1837368164W film capacitor is used in motor starting circuits as a snubber capacitor, and in audio circuits as an AC coupling capacitor for signal coupling.

Working Principle of MKP1837368164W Film Capacitor

The working principle of the MKP1837368164W film capacitor is based on the dielectric properties of a film material. In a film capacitor, two metal plates are separated by a thin film dielectric material. When a voltage is applied across the plates, the electric field generated between the plates interacts with the dielectric material, causing the electrons in the material to be polarized. The polarization of the dielectric material generates a static electric field, which adds to the electric field generated by the voltage, and thus increases the overall capacitance.This phenomenon can be explained by the equivalent circuit model of a film capacitor, which consists of two capacitors in parallel, one in series with a resistor. The series component represents the dielectric losses of the film capacitor, and the parallel component represents the pure capacitance. This model explains how the dielectric losses of the dielectric material generate an increase in the total capacitance.

Conclusion

In conclusion, the MKP1837368164W film capacitor is a high power film capacitor with a wide range of applications, including DC filters, motor starting circuits, and audio circuits. Its working principle is based on the dielectric properties of the film material, where an electric field interacts with the dielectric material, causing it to be polarized and increasing the overall capacitance.
