Film Capacitors

Film capacitors, also known as polymer film capacitors, are electrical devices that store energy in the form of an electrostatic field between two conductive objects. They are non- electrolytic capacitors with a wide range of features and low equivalent series resistance (ESR) value. Film capacitors are made of three components: a paper layer (or film) is between two electrodes, which are usually metalized polypropylene or polyester films. They are used for their low-loss, low- inductance and high-temperature characteristics. The material used in film capacitors is also important in determining their frequency response.

BFC247086823 Application Fields

BFC247086823 film capacitors are used in various fields including electronics, communications, automotive, audio and industrial applications. In the medical field, BFC247086823 capacitors are used for optical and infrared sensing, energy surge protection and other high-voltage applications. In aviation, they are used for accurate gauge readings, navigation equipment and satellite communication. In the automotive industry, they are used in air bag control systems, window defrosters and power steering systems.

BFC247086823 Working Principle

A film capacitor works on the principle of electrostatic induction. When a voltage is applied to the two electrodes, a current is induced between them. This current is proportional to the voltage applied and travels through the dielectric. The charge on the film creates a capacitive effect that stores energy in the form of electric field.The electric field of a BFC247086823 capacitor is different from that of a conventional electrolytic capacitor. It is made up of multiple layers of metalized film, each layer being slightly thinner than the previous one. This creates a series of layers of metallic oxide films, which provide a higher capacitance, lower equivalent series resistance (ESR) and accurate frequency response.The overall cost of a BFC247086823 capacitor is also lower than a conventional electrolytic capacitor due to its reliable and long-term operation. Its electrostatic field, high capacitance, low ESR, and accurate frequency response make it suitable for different applications.
