What is the role of film capacitors

Film capacitors are also called plastic film capacitors in the living environment. They mainly use plastic film as a dielectric. Due to the different electrical qualities of capacitors, there are many types of capacitors. For example, electrolytic capacitors, air capacitors, paper capacitors and film capacitors. In terms of application, they are chasing after each other, and they have made great contributions in their respective fields of discovery. At the same time, it also brings many benefits to people's lives.

It is mainly made of metal foil as the electrode, and then it works by electric energy. Because it has many excellent characteristics, it is an excellent capacitor, just like the common knowledge characteristics in science and technology, non-polarity, good insulation resistance and so on. All, many analog circuits will choose it, and it is safe and reliable, and can reduce the harm to people themselves.

In addition to being used as circuits, film capacitors have many uses. They can be seen in many industries such as electronics, home appliances, telephones, and electrics. Many people are exposed to these things every day without knowing it.  It is made of film capacitors.

Film capacitors are widely used, such as air conditioners, refrigerators, washing machines, fans, power supplies, and so on. Film capacitors are also involved in the transportation industry. What role does film capacitors play in the application field?

1) Application in power electronic circuits. Film capacitors are used here, mainly to buffer and clamp the power current, resonant bypass, and suppress the electromagnetic interference of the power supply.

2) When the film capacitor is used as a bypass, it mainly plays a role in reducing the impedance of the DC bus and absorbing the ripple current from the load, thereby effectively suppressing the fluctuation of the DC bus voltage due to a sudden load change.

3) When the device is used in a resonant converter, it can achieve resonance together with the inductor.

Film capacitors play different roles in unused areas. We must be clear about the application of film capacitors, so that they can be used more easily. If you have technical questions, you can consult us, we can provide samples for free, and more high-quality film capacitors are available in Anhui Safe Electronics Co.,LTD.
