Film Capacitors: 105PSB700K4H Application Field and Working PrincipleFilm capacitors, also known as plastic film capacitors, are capacitors in which the dielectric is a film of polyethylene terephthalate (PET), polystyrene, polypropylene, polycarbonate, polyester, polyimide or other organic polymer. Unlike similarly shaped ceramic or mica capacitors which use a solid ceramic dielectric, film capacitors employ a plastic film dielectric layer that is either etched or wound like a coil. The film capacitor can therefore be readily bent or shaped into any configuration.The 105PSB700K4H is a type of film capacitor specifically designed for high-voltage applications. It is advanced technology, providing high reliability and a long operational life at a relatively low cost. This type of capacitor is particularly useful in applications where it is required to maintain signal integrity. Its design allows for high frequency operation which makes them more suitable for radar, communication, and high voltage power line applications.The 105PSB700K4H’s construction is made up of several components including a dielectric, a metal, an insulated core, and a face plate. The dielectric, which is the most critical element, is a thin polymeric film or other material that serves as an insulator between the plates of the capacitor. It is important that the dielectric be strong and non-conductive in order to ensure maximum charge storage. The dielectric is usually formed into a roll, which is then put in a pressurized vacuum in order to ensure consistent dielectric characteristics.The metal component is generally made up of aluminum, aluminum oxide or other conductive material. This serves as a conductor between the plates and is responsible for charging and discharging the capacitor. The insulated core is a non-conductive material used to protect and insulate the dielectric and metal components from each other. The face plate is also made of a non-conductive material and serves as a barrier between the components to ensure maximum heat transfer.The working principle of the 105PSB700K4H is simple and consist of two layers of dielectric material with one layer of metal conductors between them. An electrical current is sent through one layer of the dielectric material and a charge is stored on the metal plates. Reversing the current causes the charge to be drawn off the plates and released again as the voltage reverses. This process of charging and discharging the plates causes a magnetic field to form around the plates. The magnetic field produces an electric field that can be used for various functions such as audio speakers or for signals to be transmitted.The 105PSB700K4H is an extremely versatile component that is used in many applications. It offers superior efficiency, high reliability, and long service life. It is desirable in high voltage applications as it ensures the maximum charge storage. Its simple construction also makes it fairly easy to assemble and install. For those reasons, the 105PSB700K4H is an ideal solution for a variety of needs.
