Film capacitors are widely used in electrical and electronic equipment due to their physical and electrical characteristics.They are characterized by a low loss factor, large capacitance stability,high insulation resistance, wide frequency response, high temperature and voltage resistance characteristics. ECW-FD2J185JC is a high performance film capacitor,which of the principle of working is based on dielectric physics. It mainly consists of a metal deposition electrode, dielectric film layer and the electrode. When it is working under the Electric field, the electric field intensity is proportional to the potential difference between the two electrodes . The electric flux lines are concentrated in the dielectric layer, part of the electric field distributes to the internal part of the capacitor and a few part distributes to the external part of the capacitor, due to the presence of the electric field, the dielectric layer will be polarized, and a Coulomb\'s force will be produced as well resulting a certain electric capacity.

ECW-FD2J185JC film capacitor has been widely used in industrial and consumer electronic applications which require reliable and accurate performance, such as circuit breakers, instrumentation, measuring tools, etc. It is more stable and reliable than the other capacitor types, it can be used to filter, rectify, store and release energy over a long period of time.

Film capacitors have been widely applied to power factor correction, power filtering, energy storage and harmonic reduction. The features of ECW-FD2J185JC film capacitors including individual approval certificate, proportional temperature to voltage coefficient, extended range operating temperature and good electrical strength. The main advantages of the ECW-FD2J185JC film capacitor are very high capacitance stability and high-temperature operation. Compared with other types of capacitors, the ECW-FD2J185JC film capacitor has a very low ESR values, which makes it very suitable for high frequency applications.

The working principles of the ECW-FD2J185JC film capacitors are based on the variable capacitance principle with the dielectric oscillation phenomenon which is derived from the physical phenomenon of dielectric. When the voltage of the capacitor increases, the internal electric field strength increases, consequently, the charge increases, leading to a decrease of the capacitance and a rise in the resistance,which are inversely proportional. The capacitor remains in this state until the voltage is changed again. The voltage passing through the ECW-FD2J185JC film capacitor will cause a mutual interaction between the electric field and dielectric electron, and accordingly, the dielectric layer will oscillate, allowing a current to flow through and the generated energy will be stored in the capacitor. This energy will then be released in a directed and stable manner depending on the shape of the capacitor.
