Metallised polypropylene film capacitors are a type of electrical component used in various electronics applications. These capacitors offer several benefits over other types of capacitors, making them a popular choice among engineers and manufacturers. In this article, we will explore the advantages of metallised polypropylene film capacitor and their applications in electronic devices.
What are Metallised Polypropylene Film Capacitors?
Metallised polypropylene film capacitor is made from thin layers of polypropylene film that are coated with a layer of metal. The metal coating is usually aluminum or zinc, which provides conductivity to the capacitor. The metal coating covers both sides of the film, creating a sandwich-like structure that is then wound into a cylindrical shape. This design creates a capacitor that is highly efficient, durable, and reliable.
