Film Capacitors: MKP385543085JPP2T0 Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors, are electrical capacitors with a solid dielectric such as polypropylene and polyester (PET). They have a range of different uses but are mainly used in audio frequency applications, from high frequencies to low frequencies. Film capacitors are most commonly associated with memory circuits in consumer electronics and audio systems. This article will discuss the application fields and working principles of the MKP385543085JPP2T0 film capacitor.The MKP385543085JPP2T0 is a polyethylene-terephthalate (PET) film capacitor with a maximum operating temperature of 105°C. It has a capacitance of 0.47uF and is rated at 6800 volts DC. The capacitor is a bipolar type with three capacitor plates; one positive, one negative, and one neutral. It has a maximum ripple current of 0.05A and a self-healing metalized outer coating with low ESR.The MKP385543085JPP2T0 is primarily used in audio applications, especially low frequency bass and subwoofer applications. It is also suitable for high frequency audio applications, such as surround sound systems in home theaters. Additionally, the capacitor is suitable for power supply circuits as well as various filtering applications.The working principle of a film capacitor is similar to that of an electrolytic capacitor, but instead of having an electrolyte liquid between two conducting plates separated by a dielectric, a film capacitor consists of microscopic metalized layers deposited on a thin plastic film. The metalized film serves as the two conducting plates of the film capacitor and a dielectric material is placed between the two metalized layers. The dielectric material is usually polypropylene, polyester, or some other type of plastic film.When a voltage is applied across the two metalized layers of the capacitor, electrons flow through the conducting plates, resulting in the accumulation of electrical charge in the dielectric material. This phenomenon is caused by an electrostatic field created in the dielectric material. This electrostatic field results in a capacitance, which determines the amount of electrical charge that the capacitor can store.In the case of the MKP385543085JPP2T0 film capacitor, the electrostatic field is created by the conductive metal layers on the thin plastic film and the dielectric material between them. This results in a capacitance of 0.47uF and a 6800 volts DC maximum operating voltage. The capacitor is able to store a maximum of 0.05A of ripple current, making it ideal for audio applications.In conclusion, the MKP385543085JPP2T0 film capacitor is an ideal component for audio applications, especially for low frequency bass and subwoofer applications. It is also suitable for power supply circuits and various filtering applications. The capacitor has a capacitance of 0.47uF and a maximum operating voltage of 6800 volts DC. It has a self-healing metalized outer coating for increased reliability, and a maximum ripple current of 0.05A. The working principle of the film capacitors is the same as that of the electrolytic capacitor, but instead of an electrolyte liquid, it consists of microscopic metalized layers on a thin plastic film.
