Film Capacitors

FCP1206C393J-H3 application field and working principle

Film capacitors are a type of capacitor that are composed of multiple layers of a dielectric film sandwiched between two metal plates. They are often referred to as ‘polypropylene capacitors’, as polypropylene is the most common type of film used in the construction of these components. The application for film capacitors is extensive, primarily due to their low leakage current, high capacitance, and ability to tolerate high temperatures. They are generally used in the power supply, signal coupling, filtering, and energy storage of electronic and electrical equipment. The FCP1206C393J-H3 is a polypropylene AC film capacitor, specifically designed for high-power electronic ballasts, switch-based lighting systems, dimming systems, or motor controls. It features high temperature stability, low ESR and ESL, and a lengthy service life. The FCP1206C393J-H3 has a range of standard rates, and the capacitance per when measuring the AC voltage at frequency of 50/60Hz at 20 8C. Its capacitance ranges from 0.15uF to 2.5uF, with a capacitance tolerance of ±5%. The rated voltage of the FCP1206C393J-H3 is 300V AC, maximum operating temperature is 105oC, and insulation resistance is 5,000MΩ.The FCP1206C393J-H3 is a polarized film capacitor, meaning that it will only operate in a single direction, as the two leads are physically marked as positive and negative. The capacitor’s polarity must be observed and respected when installed in a circuit.The working principle of the FCP1206C393J-H3 is the same as any other capacitor; it is designed to store and release electric charge between two conducting plates in the form of an electric field. This is achieved when an electrical current is conducted through the capacitor, giving it the ability to store the charge. The charge that is stored in the capacitor will remain in place until the capacitor is either discharged or removed from the circuit. When an AC voltage is applied to the FCP1206C393J-H3, it will act as an impedance, limiting the amount of current that can pass through the capacitor, thus serving to filter the AC voltage. This is accomplished by the film dielectric material, which is deposited on the metal plates and actively resists the flow of current.In conclusion, the FCP1206C393J-H3 is a high-power AC film capacitor that is designed for use in electronic ballasts, switch-based lighting systems, dimming systems, or motor controls. The capacitor is designed to store and release an electric charge between two conducting plates, which is achieved by the film dielectric material, which is deposited on the metal plates. It is a polarized capacitor, meaning that it must be oriented correctly in the circuit so that its polarities match those of the circuit. It is capable of an extended service life due to its high temperature stability and low ESR and ESL.
