Working Principle

The F1778368K3FCB0 is a type of film capacitor that utilizes polyester film and a metal coating to form a “dielectric” material. The dielectric material insulates two electrodes, called the anode and the cathode. When a voltage source is connected across these two electrodes, an electric field is created, allowing for the capacitance. The capacitance of the F1778368K3FCB0 is determined by the area of the electrodes, the distance between them, and the relative permittivity of the dielectric material.

When current passes through the capacitor, electrical energy is stored in the electric field, which is then released upon discharge. This phenomenon is known as “capacitive reactance” and forms the basis of the working principle of the F1778368K3FCB0 and other film capacitors.

In addition to providing a high capacitance-to-size ratio, film capacitors are also capable of providing excellent stability and temperature performance, making them an ideal choice for demanding applications. Additionally, film capacitors are capable of withstanding frequencies up to several hundred kilohertz, allowing them to be used in a variety of high-frequency circuits.
