Film Capacitors
BFC230344395 application field and working principle
Film capacitors, also known as plastic film capacitors, or more commonly referred to as MKTs or Metallized Polyester Plastic Film Capacitors or Thin Film Foil Capacitors, are a type of capacitor that uses a dielectric made of condensed plastic films. It is composed of two or more conductive metallic film layers, and its structure generally includes an insulating film layer, a dielectric film layer, a terminal lead and an outer casing.Film capacitors also have the advantages of small intrinsic inductance, wide voltage range and strong dielectric.BFC230344395 is an aluminium electrolytic capacitor with a cylindrical aluminium body, H type anode, and two external leads. It is comprised of aluminium foil electrodes, an insulation paper sleeve and an electrolyte. Its main feature is the large capacitance, low equivalent series resistance, long life, good stability and strong anti-interference ability.BFC230344395 is widely applied in frequency-adjusting, interrupting, filtering, energy storage, smoothing, signal pulsing, resonant charging and discharging, circuit damping, electronic switching, signal processing, digital signal processing and other fields. It is also widely used in computer peripherals, telecommunication equipment, instruments, military, power supplies, digitally digital circuits, switches, motors, transformers, rectifiers, storage devices and other fields.The working principle of BFC230344395 is based on the dielectric principle. The dielectric film between the two electrodes is used to store electric charge and form electric field. In the process of charge and discharge, the electric charge stored in the film is released through the electrodes. This process also takes a certain time, and the time delay of electric charge and discharge constitutes a capacitance.Because dielectric film of Film Capacitors has higher permittivity, dielectric layer\'s thickness could be reduced to produce capacitance with same volume. And the dielectric film layer has a certain insulation effect, so the voltage withstand capacity is high. In addition, because of its small size, the type size of Film Capacitors could be much smaller than other capacitors, such as aluminum electrolytic capacitors, tantalum electrolytic capacitors and mica capacitors.In conclusion, BFC230344395 application field is very wide and its working principle is very simple, which is based on the dielectric principle. It has the advantage of high voltage resistance,high capacitance,small volume,good stability, strong interference suppression and so on. It is widely used in digital circuits, motors, rectifiers, telecommunication equipment, computers and other fields. In the process of application, if its requirements are not met, it may cause some adverse effects on circuit because of its high dielectric, such as false capacitance, temperature sensitivity and polarization. Therefore, it is necessary to pay attention to product selection, circuit design and component parameters to avoid these problems, so as to ensure the reliability of circuit design.The specific data is subject to PDF, and the above content is for reference
