IntroductionFilm capacitors, also known as foil capacitors or metalized film capacitors, are made from a thin polyester or polypropylene film bonded to metal tabs and wound into a cylindrical shape. They are used in a wide range of industries and applications where stable capacitance and low-loss characteristics are required. This article focuses on the specific model MKP1845468405 and its application field and working principle. Application Field of MKP1845468405The MKP1845468405 is a film capacitor commonly used in power factor compensation networks, low/high-frequency high-noise filter networks, switching power supplies and other energy storage applications. It is also used as a part in light shading coils or motor start/run coils for AC motors. In addition, these capacitors are widely used in audio systems, broadcast equipment, and musical instruments to reduce unwanted noises.Working Principle of MKP1845468405The capacitance of a film capacitor is determined by the thickness, dielectric constant, and area of the film used to construct the device. The MKP1845468405 is a polypropylene film capacitor, with a maximum capacitance value of 100uF and a rated voltage of 630VAC. As with all capacitors, this model works by means of electrical energy being stored in its electric field and released once the capacitor is discharged. When the capacitance is charged, positive ions move to one electrode, while negative ions move to the other. These ions move to the respective electrode and generate an electrical field between them. When the voltage drops, the ions return to their original position, thus releasing the stored energy. ConclusionThe MKP1845468405 is a widely used film capacitor with a variety of applications in power factor compensation, noise filters, audio equipment, and motor start/run coils. Its working principle relies on positive and negative ions being moved to respective electrodes, creating an electrical field that stores electrical energy. This stored energy is released when the capacitor is discharged, completing the cycle.
