When it comes to its working principle, the FCN2820G393J has a dielectric layer between two metallic layers and is usually coated with plastic material. The two metallic layers are separated by an electrically insulating dielectric material which is a very thin film of material. The dielectric medium is responsible for the capacitance properties of the film capacitor and is what determines the value of the capacitance.

When an AC voltage is applied across the capacitor, an electric field is created in the medium and the electrons are moved from one layer to another. As the electrons travel from the negative layer to the positive layer, the negative electrons are attracted to the positive layer and the positive electrons are attracted to the negative layer. This transfer of electrons results in a movement of charge and is what creates the capacitance of the capacitor.

Overall, the FCN2820G393J is an excellent film capacitor that is used for a variety of applications. It is highly suitable for a range of high voltage, high temperature and medium frequency circuits, making it a great choice for applications such as television, radio and other audio applications. Additionally, it is a great option for use in conventional power supply circuits due to its extremely slim size and excellent temperature stability. It also has excellent performance as a high frequency resonance type of capacitor, making it perfect for signal transmission and reception.
