Film capacitors are versatile electronic components designed for use in various types of electrical circuits. They have the ability to store electric charge and provide energy when needed. Film capacitors are constructed from thin plastic films, usually polypropylene, polyester and polystyrene, that act as dielectric insulation between two metalized surfaces that form the capacitor\'s electrodes. This construction allows them to be used in different applications such as AC rectification, rapid charge and discharge and voltage dividing. One example of a film capacitor is the ECW-HC3B104JA.

The ECW-HC3B104JA is a compact, two-terminal polyester film capacitor that comes with a mostly standard capacitance and rated voltage of 10μF, 2.5V. It is suitable for use in a variety of applications, including light ballasts, audio circuits and AC power supplies. The capacitor has a wide decoupling range, making it useful for high-precision decoupling applications.* It also has a low equivalent series resistance (ESR), allowing high-frequency operations. Additionally, it has a maximum dissipation factor of 0.07, which improves its efficiency in storing energy.

The working principle of a film capacitor is based on the relationship between capacitance and electric field. An electric field is created between the two conducting surfaces when a voltage is applied to them. As the electrical field increases, the electrons move away from the positively charged electrode and become trapped by the dielectric insulation layer, accumulating negative charge. This accumulation of charge is known as capacitance. When the same amount of charge is applied to the negative electrode, the electrical field collapses. The energy is released and stored in the electric field.

In summary, the ECW-HC3B104JA is an example of a film capacitor that can be used in many different applications. It is a two-terminal capacitor with a rated voltage and capacitance of 10μF and 2.5V respectively. It is useful for decoupling, has a low ESR and offers excellent capacitance stability. The working principle of a film capacitor is that electrodes accumulate charge, forming an electric field, and the energy is released when the electric field collapses.
