Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of electrical component commonly used in high-frequency switching power supplies. The capacitors are constructed with a dielectric film which is wound into a cylindrical shape and covered in a protective shell. This type of capacitor provides very low levels of electrical leakage and has a number of advantages over traditional electrolytic capacitors, including reduced size, higher capacitance, and greater temperature stability.

MKP383510040JKM2T0 Application Field and Working Principle

The MKP383510040JKM2T0 film capacitor is a capacitor used in high-frequency switching power supplies for filtering and coupling applications. The MKP383510040JKM2T0 has a capacitance of 4.0µF±20% and a voltage rating of 30VDC. The MKP383510040JKM2T0 is suitable for applications that require high-frequency switching, such as those found in radio and television broadcast equipment or computers. The structure of the MKP383510040JKM2T0 is composed of a plastic film, which can be PEN, PET, PP, or PC, rolled into a cylinder and covered in a protective shell. The capacitor shell is then filled with an insulating liquid and sealed.The inner structure of film capacitors is simple. It consists of two electrodes and an insulating film. When an electric field is applied, the electrons on the positive electrode will be attracted to the negative electrode, and the negative electrode will be attracted to the positive electrode, resulting in a charge being stored. When a voltage is applied across the terminals, an electrostatic field is produced between the electrodes and the dielectric, causing charge to accumulate on the electrodes and storing a charge of electricity. The capacitor will release the stored energy when the applied voltage is removed. The capacitance of the capacitor can be adjusted by varying the thickness of the dielectric film as well as the area of the electrodes.
