Polypropylene has excellent electrical characteristics, low dielectric losses, high insulation resistance and a low temperature coefficient of capacitance. When an electric field is applied between the capacitor\'s two electrodes, an electric field is created inside the capacitor, which causes the electrons to move in an oscillating manner. This creates an electrical charge on the surface of the capacitor and increases its capacitance capacity.The SFD66T30K391B-F’s construction is also quite important for it to work properly. It consists of two electrodes with a film dielectric between them. The two electrodes are usually made of metallized polypropylene, which increases the surface area and allows for a higher capacitance. Connections between the capacitor and the circuit are made with two metallized polypropylene leads, which are soldered to the circuit. This arrangement ensures a secure connection between the capacitor and the circuit.The SFD66T30K391B-F is mainly used in automotive, industrial, and consumer applications. In automotive applications, it is typically used for power supply filtering in power systems, while in industrial applications, it is used in signal filtering, amplifier circuits and other specialty applications. In consumer electronics, it is used for signal filtering, such as noise cancellation in audio systems, as well as in power supply decoupling for motherboards, LCDs and other electronic devices.In conclusion, the SFD66T30K391B-F is a reliable and high-performance film capacitor designed for a wide range of applications. It is characterized by excellent self-healing, high voltage performance and long service life. Its construction is secure and connections between the capacitor and the circuit are easily done with its two metallized polypropylene leads.
