Film Capacitors

Film capacitors, also known as film dielectric capacitors, are capacitors that use a plastic film as the dielectric. They are constructed with metalized electrodes deposited on the surface of the plastic film. In comparison with other types of capacitors, film capacitors provide excellent long-term reliability and stability, low dielectric losses, wide temperature range, and low parasitic elements. As a result, film capacitors are widely used for energy storage, signal coupling, power grid filtering, dv/dc converters, and noise suppression.

BFC246751105 Application Field and Working Principle

BFC246751105 is a type of film capacitor featuring high dielectric strength, low leakage current, long-term durability, stability, and wide temperature range. These characteristics make BFC246751105 capacitors ideal for high-frequency applications such as AC power lines, DC-DC converters, and other power supply circuits. The BFC246751105 capacitor operates on the principle of capacitance, which is the ratio of the charge stored on the capacitor to its applied voltage. When a voltage is applied across the two terminals of the capacitor, electric charges accumulate on the surfaces of the electrodes, creating an electric field in the dielectric material. The dielectric material acts as a medium for the electric field and opposes the changes in electric potential, resulting in the storage of energy. The working principle of the BFC246751105 allows it to act as a filter in power supply lines and to stabilize voltage fluctuations.
