Film Capacitors

A film capacitor is an electronic component consisting of two electrical conductors separated by an insulating film. They are commonly used for higher voltage AC applications, and are often used in place of electrolytic capacitors where higher temperatures, ripple currents or dielectric strength requirements have to be met. In this article, we will discuss the application field and working principle of the 100ST473MA23216 film capacitor.

Application Field

The 100ST473MA23216 film capacitor is an advanced AC film capacitor that is perfect for use in applications such as the lighting components of fluorescent fixtures, switch mode power supplies, and motor AC applications. It is also suitable for use in high-frequency and high-temperature applications. In addition, it can be used in automotive electronic control systems, as well as communication and instrumentation applications.

Working Principle

The working principle of the 100ST473MA23216 film capacitor is based on the effective use of Faraday’s Law. This law states that the voltage of any two electrical conductors separated by an insulating material will store more charge if the electric field lines between the two conductors are straight and continuous. By connecting the two conductors together and applying an alternating current, the electric field lines will cause the conductors to accumulate opposite charges and store them as an electrical field within the film material. This process is known as capacitance and is directly related to the geometry of the film and the area of the two conductors. As the electric field lines become more continuous and intense, the capacitance increases.

The 100ST473MA23216 film capacitor is constructed with a high-performance film which is engineered to deliver superior capacitance and temperature performance. The film consists of a layer of polypropylene which is surrounded by a layer of cross-linked polyolefin. This combination gives the capacitor its excellent electrical properties, making it suitable for applications ranging from low-frequency to high-frequency, and from low-temperature to high-temperature applications.

Benefits

The 100ST473MA23216 film capacitor offers a number of benefits over other capacitors. For example, the capacitor has an extended temperature range and improved ripple current capability, allowing it to operate in extreme temperature and voltage conditions. Additionally, the capacitor has a superior dielectric strength, making it an ideal solution for low ESR and high capacitance applications. The capacitor also provides a greater efficiency and power factor in comparison to other capacitors.

Conclusion

The 100ST473MA23216 film capacitor is an advanced AC film capacitor that is perfect for use in applications such as lighting components of fluorescent fixtures, switch mode power supplies, and motor AC applications. Its combination of superior electrical properties, extended temperature range, improved ripple current capability, and superior dielectric strength make the capacitor an ideal solution for low ESR and high capacitance applications.
