Film capacitors, also known as film dielectric capacitors, are passive two-terminal electrical components that use a dielectric film as the medium. As a type of capacitor, a film capacitor is used to store electrical energy and block direct-current while allowing alternating-current to pass. The ECQ-E6824KF is one type of film capacitor that exhibits superior electrical characteristics and is suitable for use in power electronics and lighting applications. This article will explain the application field and working principle of the ECQ-E6824KF.The ECQ-E6824KF is a low-impedance, three-terminal SMD plastic film capacitor designed for AC power system applications. It has a working voltage of 250V and is rated for a brief pulse current up to 160A. It has a high temperature rating and a low ESR (equivalent series resistance) and high ripple current capability. Due to its low impedance, it is suitable for applications such as switching power supplies, motor drives, and high power output inverters. The capacitor also has excellent surge stability and can be used in high temperature applications.The ECQ-E6824KF is constructed using a metallized polyester film, an electrolyte, and electrodes. The dielectric is composed of a thin metallized polyester film coated with an epoxy resin. This configuration allows the metallized film to store the electrical charge and the resin to act as a protective layer. The electrolyte is a liquid or polymer that permits current to pass between the electrodes. The electrodes are composed of nickel and chrome which act as contact points for the capacitor and as a conductor for electric current. The electrodes are often encased in epoxy or wound using insulation film.The functioning of the ECQ-E6824KF is based on the electrostatic principle. When an AC voltage is impressed on the ECQ-E6824KF, an electrostatic field is generated between the electrodes and through the dielectric. This electrostatic field allows the capacitor to store the electrical charge. The stored charge then creates a potential difference between the two electrodes of the capacitor. This potential difference is the voltage drop of the capacitor. As the applied voltage increases, the electric field strength increases along with the capacitor’s capacitance and its ability to store charge.The ECQ-E6824KF is a highly reliable capacitor and has excellent insulation properties. Its ability to withstand transient overvoltages and intense currents, coupled with its low impedance, make it suitable for use in a variety of power electronics applications. Its low ESR also makes it ideal for high-power applications, eliminating the need for bulky external snubber networks or transformers.In conclusion, the ECQ-E6824KF is a reliable and robust film capacitor suitable for AC power systems applications. It has a high temperature rating and low ESR, making it ideal for high-power applications. The ECQ-E6824KF is able to store electrical charge and create a potential difference between the two electrodes when an AC voltage is applied, allowing the capacitor to operate efficiently and reliably in power electronics applications.
