Film capacitors, also known as plastic film capacitors, polyester foil capacitors and polycarbonate foil capacitors, are non-polarized electrolyte-filled electrical components made of multiple layers of polyethylene terephthalate (PET) film or polycarbonate film as the dielectric, and metallic electrodes sandwiched between two polyester or polycarbonate film layers. The fluid electrolyte is usually a mixture of ethanol and ethylene carbonate.The application field for R46KN4100JHN2M, a particular film capacitor, is very diverse. It is used for a variety of applications, including voltage stability, filtering and damping. It also offers high degree of stability in soldered condition and flexural strength.In terms of its working principle, film capacitors are usually used to couple different frequencies by creating a short connection between two components at specific frequencies. Each frequency has its own internal capacitor, with the capacitance varying depending on the application. The more the capacitor is charged with respect to the higher frequency, the higher its impedance at that frequency. This principle is especially helpful in the audio and radio applications, where filtering and damping of certain frequencies is necessary.In general, film capacitors have fairly low-efficiency when compared to other capacitor types. They also lack the ability to handle high voltages, and generally, devices containing them must be treated with extreme care. In addition, film capacitors have very low tolerance and they will loose their charge quickly in comparison to other types.In order to compensate for these drawbacks, some manufacturers have begun producing porous film capacitors. These contain tiny pores in the polymer layer that allow the electrodes to come into contact with the electrolyte, thus, giving the capacitor greater capacity and longer life.Overall, film capacitors are an essential component in a wide range of industries. They are used in numerous applications such as power supplies, home and automotive audio, instrumentation and telecommunication systems, as well as industrial automation. R46KN4100JHN2M is just one example of many types of film capacitors, each with their own specific application fields and working principles.
