F1778415M3FCB0

Film capacitors, also known as film dielectric capacitors, are electrochemical capacitors, which are made of metal foil electrodes and plastic film as the dielectric medium. The F1778415M3FCB0 is one specific type of film capacitors. It has multiple applications and works through a basic principle: electrostatics.

Application Field

The F1778415M3FCB0 can be used for many applications. For example, it can be used o tuning circuits, as a signal bypass for high sensitive signals, as a noise suppressor in switching power supply, as a basic energy storage element or as a frequency-dependent attenuator. In addition, it is also applied for motor control, as a decoupling capacitor for audio signals and as a dynamic filtering element in a high frequency circuit. In short, wherever large capacitance but small volume is needed, the F1778415M3FCB0 is the ideal device.

Working Principle

The F1778415M3FCB0 works through electrostatics. As we know, when two conductors possess different charge, the space between them will produce electric field, which is an electrostatic field. Moreover, we also know that capacitance is the ability to store electric charge and the electrostatic field will generate an electric flux when enough charge has been accumulated on the opposed both surfaces.

Working as a capacitor, the F1778415M3FCB0 could provide a certain amount of charge storage, due to the presence of electric field between its two foil electrodes. During its work, electrons will move from one electrode to the other, which will consequently generate a strong electric flux between the two, making it a working capacitor. Therefore, when a battery is connected to the circuit, electrons will be attracted and move towards the positive electrode, making it charged while the other negative electrode will be left behind with less electrons.

In summary, the F1778415M3FCB0 is a type of film capacitors that most often used in stabilizing circuits for noise suppression, bypassing signals and other areas. its working principle is based on electrostatics, which generates electric flux between the two facing electrodes and therefore provides charge storage.
