Film Capacitors

Film capacitors are a type of capacitor that comes in various forms. They are usually rated between 0.001µF and 2µF and have much higher insulation resistance than ceramic capacitors. Film capacitors are also known as Polypropylene capacitors or PP capacitors due to the fact that polypropylene film is used as the dielectric material in most cases. The DPPM16D47K is one type of film capacitor and it is used in various applications.

DPPM16D47K Application Field

The DPPM16D47K is a type of film capacitor that is used in various applications such as high voltage pulsed circuits, in RF circuits, and audio circuits. This type of capacitor has a high voltage withstand power and is suitable for situations where dielectric absorption and slow time-constant characteristics are not necessary. The DPPM16D47K is also used for filtering and in DC-DC converters.

Working Principle of DPPM16D47K

The working principle of the DPPM16D47K is based on a dielectric made of polypropylene film, which is a type of plastic with a high breakdown voltage. The dielectric consists of metal foil electrodes that are sandwiched between two layers of polypropylene film. When a voltage is applied through the capacitor, the capacitor stores an electric charge between these two metal foils. This stored electrical charge is the capacitance and it is used to filter or block the flow of electricity.The DPPM16D47K has a low equivalent series resistance, or ESR, which allows it to handle large current spikes without losing its capacitance. This makes the DPPM16D47K suitable for high voltage pulsed circuits and audio applications. The low ESR also helps reduce the amount of noise in RF circuits. The ESR of the DPPM16D47K is usually in the range of 0.2Ω to 1Ω.

Conclusion

The DPPM16D47K film capacitor has a wide range of applications, including high voltage pulsed circuits, RF circuits, audio circuits, and DC-DC converters. The capacitance of this type of capacitor is stored due the dielectric made from polypropylene film, and its low equivalent series resistance allows it to handle large current spikes. All these features make the DPPM16D47K an ideal choice for many applications.
