Film Capacitors

The 460M40592-100 is a type of film capacitor that utilizes film as its dielectric material, which is designed for a wide range of application fields such as AC single- and three-phase circuits, power supply and audio equipment. Film capacitors are favored for their lower loss, higher reliability, and higher temperature capability than other capacitor types.

Application Fields

The 460M40592-100 is suitable for a variety of applications such as AC single- and three-phase circuits, power supply and audio equipment, for example, motor starters, welders, milligrams, UPS systems, electric furnace, DC-DC converters. It can be used for reducing noise, preventing EMI, and providing transient overvoltage protection. It is ideal for high-temperature and high-voltage applications due to its superior thermal resistance and electrical insulation properties.

Working Principle

Film capacitors, also known as polypropylene film capacitors, are constructed of two thin layers of electrically conductive aluminum foil separated by a thin polypropylene dielectric layer. The foil and the dielectric layers are then rolled up to form multiple layers of wound and insulating layers. These layers are then encapsulated in a metal or plastic container. When a voltage is applied between the terminals, the metallic layers become charged and this charge causes an electric field to be created across the dielectric layer, creating an impedance within the capacitor. The film capacitor is able to store a charge and can be discharged when needed.

Due to its lower loss and higher reliability, film capacitors are optimally suited for many applications that require significantly less unwanted losses compared to ceramic capacitors, as well as better temperature handling.
