Introduction about Film Capacitors

Capacitors are the most important elements in the circuits, and they are widely used in many electrical and electronic equipments. Among them, film capacitors are a kind of important capacitors which are made up of metal foil and plastic film. In comparison with other kinds of capacitors, film capacitors have lower loss, higher reliability, and better temperature properties, therefore they are widely used in power supply, communication, automotive, aerospace, instrument and other fields.

PVC4247 Application Field and Working Principle

PVC4247 is a type of polyvinyl chloride (PVC) film capacitor. It has many advantages such as low dielectric loss, high reliability, excellent temperature performance, which make it popular in power supply, communication, automotive, aerospace, instrument and other fields. The basic structure of PVC4247 film capacitors consists of two separated polyvinyl chloride (PVC) film electrodes, an dielectric layer, end-filling material and lead electrodes.The working principle of PVC4247 film capacitor is quite simple. When there is an external electric field, the positive and negative charges are separated and accumulate in the electrodes, thus forming an electric field around the electrodes. This electric field polarizes the dielectric, causing the positive and negative pole in the dielectric to attract each other, resulting in a stored energy in the dielectric. This energy is the capacitance. Through the application of the voltage, the current flows, and the electrostatic inductions are re-arranged, leading to the "charging and discharging" of the capacitor.In addition, the PVC4247 film capacitor has the following advantages:1. High dielectric strength. PVC4247 film capacitor has high dielectric strength, which makes it safe for high voltage environment.2. High heat resistance. It can work in harsh environment where its temperature may reach up to 125℃.3. Low leakage. The dielectric has extremely low leakage current, which can bring good performance in the circuits.4. Long life. Its long service life makes it ideal for many applications.

Conclusion

As a kind of important electronic component, the PVC4247 film capacitor is widely used in a number of fields because of its excellent performance and reliable quality. Companies like Jiaerwei provides these kind of film capacitors to fulfill the requirements of different applications. With its advantages such as low dielectric loss, high reliability, excellent temperature performance, and long service life, the PVC4247 film capacitor are definitely the ideal choice for many applications.
