R71VF31504030K Working Principle

The working principle of a film capacitor, such as the R71VF31504030K, is based on the basic capacitance principles. As we know, a capacitor consists of two conducting plates that are separated by a dielectric material. This dielectric material can be different types of film such as paper, ceramic, and plastic. This dielectric material will act as an insulator, thus creating an electric field that can store electrical energy. When the capacitor is connected to an AC power source, the capacitor will be subjected to an alternating current. The alternating current will cause the electrical charge to be shifted back and forth between the two plates of the capacitor and thus it will create a alternating current.

When it comes to the R71VF31504030K film capacitor, it features a plastic dielectric that is highly resistant to heat and moisture. Due to this, it can withstand temperatures up to 110C and can perform well in extreme environmental conditions. Additionally, this film capacitor includes a full-length winding process and adhesive backing, thus providing stable capacitance, low losses, and low dielectric absorption rate. With these features, the R71VF31504030K is highly reliable and suitable for many uses.
