Working Principle

Film capacitors have two parallel plates (electrodes) between them, with a dielectric material sandwiched in between. This structure then provides the structure a specific capacitance, making it an ideal component for a wide variety of high frequency applications.

The capacitance of the film capacitor is based on the initial charge on the plates. When a voltage is applied to the capacitor, a portion of the charge moves to the positive plate, while the other part moves to the negative plate. As the charge moves, the charge on the plates begin to increase, resulting in a decrease in the capacitance that is proportional to the voltage. This relationship between voltage and capacitance is the basis of the working principle of film capacitors.

The film capacitors also exhibit excellent insulation and high frequency characteristics, which make them ideal for high frequency applications. They are also able to withstand higher temperatures than other types of capacitors, making them suitable for use in high temperature environments.

In addition, the film capacitor is also designed to be more resistant to environmental conditions, making them more durable and reliable in the long term. The film capacitor also has excellent EMI (electromagnetic interference) suppression characteristics, making it ideal for communications, audio/video applications, and in applications where high voltage pulses are expected.
