Introduction to Film CapacitorsThe world of capacitors is vast and varied. In its most basic form, a capacitor is an electrical device composed of two conducting plates, metal or otherwise, separated by a dielectric medium. When a voltage is applied to the two plates, current is drawn, causing a charging effect. Within the world of capacitors are several types and each type has its own strengths, weaknesses and benefits. One such type is the film capacitor.What is a Film Capacitor?A film capacitor (also known as film dielectric capacitor) is a capacitor that uses a plastic film as its dielectric material. The plastic film is usually polyester, polypropylene or Teflon. Polyester and polypropylene are the most common plastic films used in film capacitor construction.When a voltage is applied to a film capacitor, the dielectric material becomes polarized causing electrical field that produces an effect known as capacitance. This property is measured in Farads (F) and is dependent on the dielectric material in the capacitor.The design of a film capacitor is simpler in construction than other capacitor types. It consists of two metal foils separated by the dielectric plastic film. Contact is made on both metallic foils with a conductive coating of metal or graphite.Advantages of Film CapacitorsFilm capacitors are known for their high reliability, high capacitance in small package form, stable capacitance over a wide temperature range and ripple current handling capabilities.Other advantages of film capacitors include a low cost, low ESL (equivalent series inductance), low ESR (equivalent series resistance) and long leakage current life.ECQ-E10822KF Application Field and Working PrincipleThe ECQ-E10822KF is a film capacitor designed specifically for use in AC grid-connected applications. The capacitor is designed to operate with AC currents of 370V and offers a maximum rated voltage of 525V.The ECQ-E10822KF consists of two metal foils, separated by a dielectric plastic film (insulated film). When a voltage is applied, electrons migrate from one metal foil to the other and create an electrical current. The current created by the electrons causes a loss of energy, known as capacitance.The ECQ-E10822KF has been designed with a three-layer structure that allows it to be polarized, resulting in a higher level of dielectric stability and a wider operational temperature range. Additionally, the capacitor is designed with a triple-layer structure to reduce ESL and ESR levels. This provides higher capacitor stability and higher ripple current handling capabilities.The ECQ-E10822KF capacitor is specifically designed for AC grid connection applications and is widely used in lighting, automotive, general purpose and power electronics, as well as other industries.ConclusionThe film capacitor is an excellent choice for AC grid-connected applications. It is reliable, offers a high capacitance in a small package and can handle high ripple currents. The ECQ-E10822KF film capacitor is a great choice for these types of applications, offering a good combination of performance and reliability.
