Film Capacitors: MKT1822447105 Application Field and Working PrincipleFilm capacitors, also known as film dielectric capacitors, are capacitors that utilize a thin plastic film as the dielectric material. Typically, the film used in this type of capacitors consists of polypropylene and polyethylene terephthalate (PET). Film capacitors are most commonly used in AC power electronics circuits related to mains frequencies and power factor correction. Additionally, they can be used in applications such as signal processing, AC motor/solenoid control, and power supplies. The MKT1822447105 Film Capacitor is a good example of this type of capacitor.With the MKT1822447105 Film Capacitor, the capacitor consists of two electrodes with an insulating film in between. This film is usually polypropylene or polyethylene terephthalate, which has excellent insulation properties and is resistant to temperature extremes. This type of capacitor is characterized by a high voltage rating, low momentary loss, and low ESR, making it an ideal choice for many applications where a high-quality AC power electronics component is required. In terms of application fields, the MKT1822447105 Film Capacitor is ideal for use in AC power electronics circuits related to mains frequencies and power factor correction, as well as signal processing, AC motor/solenoid control, and power supplies. The capacitor is also suitable for use in noise reduction and power smoothing circuits, such as high frequency switching mode power supplies and inverters. Additionally, these components are also ideal for decoupling, line bypass, resonant tank, and noise suppression circuits. The working principle of the MKT1822447105 Film Capacitor is quite straightforward. In basic terms, when a voltage is applied to the two electrodes of the capacitor, an electric field is set up between them, which causes the electric charges to move through the dielectric material between the electrodes, forming an electric double layer. This double layer acts as a storage for the electric charges, thus storing a certain amount of energy and allowing for the passage of current through the capacitor. When the voltage applied to the film capacitor is alternating in nature, the electric double layer will also alternate, thus allowing for the passage of current through the capacitor during the alternate peaks of the voltage waveform. Over time, this current alternation yields a charge stored in the dielectric material between the two electrodes. This ability to store energy and pass current makes film capacitors highly desirable for many applications. In conclusion, the MKT1822447105 Film Capacitor offers many advantages, such as a high voltage rating, low momentary loss, low ESR, and a long life span. Additionally, this type of capacitor is ideal for use in AC power electronics circuits related to mains frequencies and power factor correction, as well as signal processing, AC motor/solenoid control, and power supplies. Through its working principle, the capacitor is able to store energy and pass current, making it highly desirable for many application fields.
