Film Capacitors

BFC237512681 Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors, are made of a variety of materials, such as polypropylene, polystyrene, paper, or even enameled wire. Film capacitors are usually made of a single material but may sometimes contain a combination of two or more. These capacitors are generally applied in rail or road based public transport, motor control systems, communication electronics, and any other application where a high degree of dielectric stability and a long life are required.Film capacitors are well known for their small size, high capacitance, low ESR, low inductance, and good self-healing properties. In addition, film capacitors are widely used in audio applications due to their relatively low distortion as well.The working principle of film capacitors is relatively simple. Film capacitors use a thin insulating film as their dielectric material. The two electrodes of the capacitor are separated by the thin layer of the film. When a voltage is applied across the two electrodes, an electric field is created between them. This electric field stores electrical energy between the two electrodes and produces the desired capacitive effect.When choosing a film capacitor for any application, it is important to consider the expected operating parameters, such as the voltage rating, current rating, capacitance, and insulation resistance. The expected temperature range of the application must also be taken into consideration since the temperature range can affect the lifetime of the capacitor. In addition, other important aspects such as the frequency response and cost must also be taken into consideration.For applications where a high level of dielectric stability and longevity are most important, film capacitors are usually the best choice. Due to their relatively low cost, small size, and good performance characteristics, film capacitors are one of the most commonly used types of capacitors in a wide range of applications.
