Film CapacitorsFilm capacitors are widely application in many areas, especially in motor control and power supply fields. In order to meet the requirements of harsh environment, 105MWR050K capacitors are designed due to the superior insulation performance, temperature endurance and superior dielectric properties.105MWR050K is a type of high temperature performance motor film capacitor. It utilizes special Polypropylene Film (PP) as dielectric medium, metallized electrode and can be used in high-voltage and high-current applications. It has superior insulation, high dielectric strength, high temperature endurance and low equivalent series resistance (ESR) characteristics.The design of the 105MWR050K is optimized to make it more tolerant to higher line voltage and frequencies, thereby making it a preferred choice for motors. It is mostly suited for the applications in various motor control fields. A major benefit of the 105MWR050K is high heat resistance, which helps it to bear the considerable heat generated in a motor.Working PrincipleThe working principle of a film capacitor is mainly related to its structure. The film capacitor consists of two metal plates with a thin insulating medium or film between them. The thickness of the film and type of metal used determine the working characteristics of the capacitor.A major benefit of using the film capacitor is its ability to store electrical energy while maintaining its charge. It can store a large amount of electrical energy and then discharge it as needed. The capacitance of the capacitor determines how much energy it can store and this is determined by the thickness of the dielectric film and the distance between the two metal plates.When the capacitor is energized, current flows through the metal plates, creating a magnetic field around the capacitor. This causes the electrons to move to one side of the film, creating an imbalance between the two plates. This imbalance creates an electric field which maintains a charge potential difference between the two plates. As the current is breaking, the opposite charges of the two plates attract each other and charge is stored within the capacitor. To sustain the electrical potential, no current is allowed to flow through the dielectric material between the two plates.ConclusionThe 105MWR050K Film Capacitor is a great choice for motor control applications due to its superior insulation performance, temperature endurance, and dielectric properties. Its working principle is based on the basic capacitance principles and it stores energy in the form of an electric field. It is also a great choice for applications where heat resistance is important.
