Film Capacitors
The MKT1813147634R is a type of film capacitor, which is a type of capacitor composed of several thin layers of metalized film interleaved with a thin layer of plastic film, providing an extremely low equivalent series resistance (ESR) and high insulation resistance. Film capacitors typically have values from digital nF through to tens of mF cap values, with operating voltages (DC blocking) ranging from 10 Vac/dc up to 55 kVac/dc, depending on the type of film capacitor chosen.
Application Field
Film capacitors can be used in virtually any application, from direct current-DC application, RF application, wave shaping, bypass application, blocking application, power supplay filtering or timing applications. The MKT1813147634R Film capacitor is able to provide higher values in a much smaller package size than other similar capacitors, making it suitable for use in a wide range of applications.
Common applications of film capacitors include snubber circuits, by-pass circuits, timing circuits, and power supplies for communication equipments. The MKT1813147634R also has wide-used in electrical instruments, luminous tubes, integrated circuits, high-voltage shielding power supply, AC/DC motor- control, audio, and digital products such as LED lamps.
Working Principle
Film capacitors are made of a thin sheet of metal foil deposited on a plastic or a paper substrate. This foil creates the electrodes and acts as the dielectric between them. The distance between the two electrodes is small, so a relatively large capacitance can be achieved in a small size. The plastic film serves as an insulation layer between the electrodes and also acts as the dielectric for the capacitor. As electrons are moved through this dielectric, an electric field is created which adds and subtracts capacitance from the device.
The MKT1813147634R has a self-healing characteristic which allows it to operate reliably for long periods of time in demanding applications. This feature is due to the thin dielectric layer which is not destroyed by arc faults. The self-healing is activated by the self-healing process that intermittently removes boundary impurities that can decrease life time of the component.
