Film Capacitors

BFC247942134 Application Field and Working Principle

Film capacitors, also known as film dielectrics, are an important type of capacitors that have been widely used since the 1950s. They have non-polar construction and typically use either polypropylene (PP) or polyester (PET) as the dielectric film. BFC247942134 film capacitors are a good example of this type of capacitor, with PP as the dielectric material.

The BFC247942134 film capacitors can be divided into three categories: metallized film capacitors, foil film capacitors, and mixed film capacitors. These capacitors are relatively small in size and have a wide range of applications in lighting, automotive electronics and consumer electronics.

The working principle of the BFC247942134 film capacitor is based on its construction. The capacitor is composed of two electrodes separated by a thin dielectric film, which serves as an insulator. When an electric field is applied to the capacitor, the positive charges on the electrode surface will be attracted to the negative electrode on the opposite side, creating an electric potential difference. This electric potential difference is the capacitance C, which is determined by the size and thickness of the dielectric film.

The capacitance of BFC247942134 film capacitors is relatively high compared to other types of capacitors. The self-healing characteristic of the capacitor also makes it very reliable and suitable for use in demanding applications. In addition, film capacitors are notable for their outstanding temperature stability, which makes them ideal for use in extreme temperature environments.

In conclusion, BFC247942134 film capacitors are an excellent choice for a variety of electrical applications, due to their high capacitance, robustness and excellent temperature stability. They are commonly used in automotive electronics, lighting, UPS power supplies, medical equipment and consumer electronics applications.
