Film CapacitorsFilm capacitors are capacitors which employ a film as the dielectric material, rather than paper or ceramic. Using plastics that have been polymerized and powdered, these capacitors store electrical charge very well in comparison to other types of capacitors, such as electrolytic capacitors, paper capacitors and ceramic capacitors. Examples of plastic film used in making film capacitors include polyethylene terephthalate (PET), polypropylene (PP), polycarbonate (PC), and polyethylene naphthalate (PEN)).Film capacitors have various applications in the electronics industry, such as signal processing, motor control, power supplies, and telecommunications. They are also used in the military and aerospace industries, as well as in medical and lighting applications. Movie, video and digital audio and video applications all use film capacitors.The ECW-U2183JC9 film capacitor is a radial, self-healing film capacitor developed for use as a snubber in power electronics. The capacitor features 3000 Volts DC working voltage, 0.092 uF capacitance and low DC leakage current. It is designed to protect electric circuits from high transient voltages. Its robust metallized polypropylene dielectric offers excellent insulation and temperature resistance, stability and self-healing properties.The working principle of film capacitors can be explained as follows: electric energy is stored in a dielectric material placed between two conducting plates. The energy is stored when electric charges accumulate on the surface of the dielectric material. The dielectric must be able to store the charge by becoming polarized due to the electric field. The electric field is created by the difference in electric potential between the two plates. Electric charge is stored in the dielectric material and is released when the capacitor is discharging. This type of capacitor is classified as a "condenser" due to its ability to store energy in the form of electric charge.Since film capacitors are made from plastic films, they are not subject to the dimensional changes associated with conventional capacitors due to temperature or humidity. This makes them ideal for automotive and other applications where conditions can change rapidly. They also exhibit excellent surge current capability, which make them suitable for use in a variety of industrial and automotive applications.In summary, the ECW-U2183JC9 film capacitor is an ideal choice for applications where high transient voltages could be encountered. It is able to store electrical energy in its dielectric material and then release that energy when needed. The capacitor’s robust metallized polypropylene dielectric offers excellent insulation, temperature resistance, stability and self-healing properties. Film capacitors are widely used in the electronics industry and other applications due to their superior performance and reliability.
