Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor that can store electrical energy in thin polymer material. They are electrolyte-free, non-polarized and compact and in general, they have low parasitic inductive effects which make them ideal for a variety of applications.

The BFC246831474 application field are primarily used in the communication, automotive, industrial and consumer electronics and aerospace sectors. The working principle of a film capacitor is mainly based on its ability to store charge in an insulating polymer which is partially filled with a mobile charge carrier.

In general, film capacitors are formed by stacking monolithic ceramic layers or plastics with alternate electrodes. The film dielectric can be either polyester, polypropylene, polycarbonate or a combination of these materials. The electrodes are usually either metal or conductive polymer which are attached to the dielectric layer via an adhesive.

Film capacitors have a lower impedance compared to conventional electrolytic capacitors. These capacitors can also handle higher voltages and temperatures, making them suitable for applications where the operating temperature is higher than the limits of conventional capacitors.

Due to their optimized voltage performance, film capacitors exhibit excellent linearity and a wide frequency response. This is due to their low parasitic inductive effects, which make them suitable for use in high frequency circuits. In addition, film capacitors also exhibit much lower leakage current compared to other types of capacitors.

In conclusion, the BFC246831474 application field and working principle are highly suitable for various applications in the communication, automotive, industrial and consumer electronics and aerospace sectors. The film dielectric and electrodes, combined with its low impedance and wide frequency response, makes it an ideal choice for these applications.
