Introduction to Film Capacitors

Film capacitors were first developed in the 1950s and are now commonly used in many types of electronic circuits. Film capacitors are non-polarized, meaning they can be connected to either positive or negative voltages without damage. This makes them ideal for applications such as automotive and telecommunication equipment, where low-profile and lightweight components are needed.

Types of Film Capacitors

Film Capacitors are available in various sizes and shapes, depending on their application. Smaller film capacitors of radial construction are typically used for things like bypass and decoupling capacitors in switching power supplies, while larger axial capacitors are often found in industrial and military equipment.

Film Capacitors generally fall into two categories: polyester and polypropylene capacitors. Both offer excellent noise suppression capabilities, while polypropylene are able to handle higher operating temperatures and voltage levels. Other types of film capacitors are also available, such as Teflon and Mylar capacitors.
