Film Capacitors

MKT1820222104 Application Field and Working Principle

A film capacitor, also known as a plastic film capacitor, polyester capacitor, or polyethylene terephthalate (PET) capacitor, is an electronic parameter that stores electric energy or a conductor to separate two elements of a circuit. It consists of metal foil electrodes laminated between two sheets of insulating material or plastic film. The MKT1820222104 is specially designed for coupling, audio, low-voltage, and timing applications.The types of film capacitors are polyester, polystyrene, polypropylene, and polyphenylene sulfide (PPS). The material used to make the MKT1820222104capacitor is polyester film. It is a combination of two electrodes, a dielectric, and a metal case. The dielectric is a PET and is highly reliable in high capacitance values. The dielectric between two electrodes is held in place by a metal housing, and the benefits are longevity and stability. It is also very small in size, making it a good choice for portable applications.The working principle of a film capacitor is simple. When there is a potential difference between two terminals, charges build up on the metal foils and a voltage is generated. The dielectric stores this voltage while keeping the two terminals insulated from each other. During the charging process, the electric field created by the voltage drives electrons from one terminal to the other. The electrons jump from one film layer to the other and build up a current which then flows into the circuit.The application of the MKT1820222104film capacitor is mainly in coupling,audio,low-voltage and timing applications. It is used in low-power applications such as for coupling,decoupling,suppression,filtering and audio applications. It is also used in low-voltage applications such as in electronic ballasts, surge protectors, and motor drives. In timing applications, it is used for controlling frequency and timing circuits such as oscillators.The advantages of using the MKT1820222104film capacitor are its high capacitance values, high stability, and low leakage. It has a wide capacitance range from 30pF to 2.2uF. It is also highly reliable and has a long lifetime. Additionally, it provides stable performance in the rated temperature range.The MKT1820222104film capacitor is an example of how film capacitors can be used in the fields of engineering and technology. It has a wide range of applications and offers advantages of high capacitance values, high stability, and low leakage. The combination of these features makes it a great choice for use in low-power and low-voltage applications.
