Film capacitors are one of the most popular capacitor families today. It is characterized by its reliable performance, long life, low dissipation factor, good frequency response, and good self-healing properties. QXK2E155JTP7FM is a type of film capacitor with polypropylene dielectric core. In this article, we\'ll discuss the application field and working principle of these capacitors.

Film capacitors are ideally suited for use in energy storage applications, such as AC motor start, DC motor start, and AC power factor correction. They are also used in general-purpose power supplies, DC/DC converters, audio and video amplifiers, and microwave ovens. For these applications, film capacitors are distinguishable for their superior electrical characteristics such as low ESR, ESL, and very high insulation resistance.

The QXK2E155JTP7FM film capacitor consists of two metalized electrodes—which are essentially layers of metal—separated by a thin dielectric core made of polypropylene. This type of capacitor is designed specifically for use in high-quality audio applications and it provides a very clean response with low levels of distortion.

The working principle of a film capacitor is fairly straightforward. When a voltage is applied to the electrodes, a charge is stored at the surface of the dielectric layer. This electric charge creates an electric field in the dielectric, which is responsible for the capacitor\'s capacitance—the amount of charge it stores in an applied voltage potential. The capacitance increases as the applied voltage increases, up until the point where the dielectric breaks down. At this point, the capacitor will no longer function.

The QXK2E155JTP7FM is designed for use in audio applications, but can also be used in other energy storage or power factor correction applications. It has superior electrical characteristics such as a low ESR, ESL, and very high insulation resistance, making it ideal for use in these applications.

In summary, the QXK2E155JTP7FM is a type of film capacitor with polypropylene dielectric core. It is designed for use in audio applications, but can also be used in other energy storage or power factor correction applications. It is characterized by its reliable performance, long life, low dissipation factor, good frequency response, and good self-healing abilities. The working principle of a film capacitor is based on the electric field created between the two metalized electrodes, which is responsible for its capacitance.
