BFC2370EE393

Film capacitors, also known as Plastic Film Capacitors, are ceramic-based capacitors built on a dielectric film. Generally, the film is made up of polypropylene, polyester, polycarbonate, polystyrene, polyimide and other materials. The BFC2370EE393 is a film capacitor, more specifically a polypropylene film capacitor. It is an AC motor run capacitor featuring an oval shape, epoxy resin-filled housing and solder pin terminals.The BFC2370EE393 is used in a variety of applications in the AC motor, fan and other industrial fields. The most important application is to filter the noise generated by AC motor. The capacitance range is 4.7~20μF, with a voltage rating of 250V and a tolerance of ±5%.In order to achieve decoupling and noise suppression, the working principle of BFC2370EE393 film capacitor is based on the principle of capacitance. It consists of two electrodes separated by a dielectric film and an electrolyte. When a potential difference is applied between the two electrodes, electric charge accumulates on the surface of the dielectric film, generating an electric field in the dielectric. The electric field then polarizes the molecules of the dielectric material, causing an electric dipole in the material. The electric dipole further interacts with the electric field, leading to a decrease in the field strength inside the dielectric. This process is known as dielectric polarization, and the resulting decrease in electric field strength is the capacitance of the film capacitor.The capacitance of the capacitor is also related to the dielectric constant and geometry of the capacitor. The larger the dielectric constant and the shape of the capacitor, the higher the capacitance. So it is important to choose the right film capacitor for the given application. Furthermore, the BFC2370EE393 is constructed with flame-retardant epoxy resin-filled housing, which provides better insulation and protection of the internal components. In conclusion, the BFC2370EE393 film capacitor is a reliable and efficient capacitor for multiple applications in AC motor, fan and other industrial fields. It provides excellent filtering of noise generated by the AC motor and offers excellent dielectric strength and insulation with its flame-retardant epoxy resin-filled housing.
