Film Capacitors

Film capacitors are the most popular type of capacitors used in electrical and electronic systems. The 947C731K801CDI is a type of film capacitor that is designed specifically for high voltage applications.

Application Field

The 947C731K801CDI is a polypropylene film capacitor with insulation. These capacitors are designed to operate reliably over a wide range of temperatures and humidities. Some applications include high voltage AC motor drives, AC and DC filters, and power-factor capacitor banks for utility applications. The 947C731K801CDI is also designed to meet military and other safety standards such as UL, CSA and IEC.

Working Principle

The 947C731K801CDI is a polypropylene film capacitor with tin-plated copper leads. Its structure consists of two layers of film that are rolled up together. One layer of the film is covered with a dielectric coating to provide insulation between the two layers and to prevent any current flow between them. The other layer is left uncovered and is used as the plate of the capacitor.

When an electric potential is applied to the capacitor, electric charges are drawn from the film\'s electrode and deposited on the plate. The charges remain on the plate as long as the voltage is maintained. When the voltage is removed, the charges on the plate are discharged and the capacitor is ready for the next cycle. This process is what allows the capacitor to store energy.

The 947C731K801CDI is rated for operation up to 200VAC and 1000F. It is designed to be a reliable, long-term solution for a variety of high voltage applications. This type of film capacitor can also be used in AC- or DC-rated applications such as motors, filters, and power factor correction.
