WMF1S39K-F

Film capacitors, also known as polyester film capacitors, are dielectric film capacitors. It is mainly composed of plastic film, metal foil and other components. The basic principle is that plastic film is used as polarization medium, and metal foil is used as pole piece. When the voltage is added between the two pole pieces, electric charge is stored in the capacitor and released when the capacitor is disconnected from the electric circuit. The most common plastic film materials used in film capacitors are polyester, polycarbonate, polystyrene, etc.WMF1S39K-F is one of the film capacitors of Shenzhen Wenming Electronics Co., Ltd. It has an operating frequency range of 68-100kHz and can be used from -40℃ to +85℃. It has a variety of applications, including renewable energy, communication equipment, unmanned aerial vehicles, industrial motor startups, induction motors, transformers and other systems.The working principle of the WMF1S39K-F film capacitor is to store electric charge in the device. When the AC voltage is input between the two pole pieces, the dielectric in the capacitor will polarize, and electric charge will be stored in the capacitor according to the theories of electronic static field. When the AC voltage is removed from the device, the dielectric will recover its unpolarized state, and charge stored in the capacitor will be released and dissipated from the device in form of electric current.The main parameters that affect the working performance and stability of the device are the capacitance value, insulation resistance and dissipation factor. The capacitance value refers to the ratio of the electric charge that the capacitor can store to the voltage applied between the two pole pieces. The insulation resistance refers to the resistance between the two pole pieces when the capacitor is not connected to the circuit. The dissipation factor is a measure of the energy lost in the capacitor due to current leakage and incomplete recover of the dielectric polarization. The lower these values, the better the performance of the capacitor.Compared with the general capacitor, the WMF1S39K-F has the characteristics of large capacity, low loss, small size, light weight, high insulation resistance and strong overload capability. Its application field mainly includes renewable energy, communication equipment, unmanned aerial vehicles, industrial motor startups, induction motors, transformers and other systems.In sum, the WMF1S39K-F film capacitor is a highly reliable and efficient capacitor that has a wide range of applications in various electrical and electronic systems due to its superior performance. This type of capacitor has excellent resistance to corrosion, moisture, heat and cold and wide temperature range.
