Film Capacitors are a type of capacitor that relies on a circuit element that stores an electrical charge and releases it when needed. The major components of a Film Capacitor are the film, the electrodes, and the connecting wires or other components. The film is an insulating material typically consisting of an organic polymer dielectric, which forms the basic structure of the capacitor. The electrodes are typically inscribed on the film with a voltage applied, and the connecting wires or other components are used to connect the electrodes to a circuit. F1778422K2FBB0 is a type of Film Capacitor, specifically a “flexible type” Film Capacitor.F1778422K2FBB0 is designed to be a reliable, high performance capacitor and to provide low loss capacitance and high reliability over temperature. It is designed for applications in consumer electronics, telecommunications, medical, aerospace and defense, and other industrial applications. The capacitor is also designed for use in high temperature and vibration environments such as automotive and aviation applications.The working principle of the F1778422K2FBB0 Film Capacitor is based on the electron flow between two electrodes. When a voltage is applied to the electrodes, electrons will flow from one electrode to the other. The flow of electrons creates an electric field in the space between the electrodes, which is referred to as the dielectric. The electric field creates a “capacitance”, which is the ability of a capacitor to store an electrical charge. Capacitance is measured in Farads (F). The F1778422K2FBB0 capacitor has a rated capacitance of 2.2 F.In order to ensure excellent reliability, the F1778422K2FBB0 film capacitor utilizes a robust design featuring interfacial polymer coating that provides high temperature stability and improved robustness against environmental stresses. Additionally, the film capacitor is designed with high corrosion resistance to ensure long term reliability.Part of the reason that the F1778422K2FBB0 is so reliable and robust is due to its construction. The flexible film is composed of a polyester film and an interfacial polyimide coating. It has an identical construction to a standard film capacitor but is specifically designed to have a more flexible form factor. This allows for easier mounting and greater reliability. The electrodes are composed of a tinned covered copper foil and aluminum foil with a catalyzed copper surface finish and burned GIT (Gaseous Inorganic Treatment) process. The construction of the F1778422K2FBB0 film capacitor ensures high reliability and durability.In addition to its design features, the F1778422K2FBB0 has a wide range of operating temperatures, ranging from -55°C to +130°C, with temperature cycling and high humidity and salt spray testing. It also boasts a resonant frequency range of 10MHz to 2GHz and excellent EMI characteristics. Overall, the F1778422K2FBB0 Film Capacitor is extremely reliable and robust and is well suited for a wide range of applications.
