Film capacitors are a type of capacitor in which the insulating material between the electrodes is very thin plastic film. Film capacitors, also known as polymer film capacitors, offer advantages such as high dielectric strength, low leakage current, and a large capacitance per unit volume. The thin low loss plastic films used as the dielectric insulation material is corrosion resistant and highly reliable.One of the film capacitors, R75LF22204000K, is widely used in the fields of power electronics, electric power systems, industrial automation, digital communication and instrumentation. In particular, it is extensively used for low frequency/high voltage applications because of its high breakdown voltage, good flame retardancy and environmental safety.The structure of R75LF22204000K is composed of two electrodes, a thin dielectric layer, end caps and a lead. Under the specified temperature, R75LF22204000K can work in the temperature range from -55°C to +105°C. It has outstanding insulation and high & stable capacitance characteristics within a wide range of humidity and temperature. In addition, its minimum dissipation factor (ESL) is relatively low, which is a great advantage over other types of capacitors.The basic working principle of R75LF22204000K is that it works like a two-plate capacitor whose plates are insulated by a dielectric. When an electric current flows through a linear circuit, electrical energy is stored in the capacitor and behaves like electrical charge carriers. The higher the electric current, the higher the voltage and the more energy is stored in the capacitor. The capacitor, due to its dielectric, prevents the current from flowing, except when a high voltage is applied to it. This stored energy can be released when a high voltage is applied to the capacitor.The advantages of R75LF22204000K capacitor include small size, large capacitance, stable capacitance, low dissipation factor (ESL), high insulation resistance and good self-healing performance. It is mainly used for low frequency/high voltage applications such as high-voltage inverters, power supplies, and high-voltage power supplies.In conclusion, the R75LF22204000K film capacitor has excellent electrical properties and performance, making it ideal for a variety of low frequency/high voltage applications. Due to its thin dielectric layers and superior insulation properties, the R75LF22204000k provides high rate of electrical energy storage. This combination of features, combined with its good self-healing performance, makes it a great choice for applications where a reliable and high-performance capacitor is needed.
