Introduction to Film Capacitors

Film capacitors, also known as film dielectric capacitors (or plastic film capacitors), are constructed using stranded metallic layers separated by plastic film. This type of capacitor consists of a thin plastic film that acts as its dielectric, an electrically conductive layer (electrode), and two additional conductive layers that act as the plate or foil. Film capacitors are usually smaller and more cost-effective than other types of capacitors, and provide excellent electrical performance, making them suitable for a wide variety of applications.

BFC236855822 Application Field and Working Principle

BFC236855822 film capacitors are an excellent choice for a variety of applications due to their superior electrical characteristics and cost effectiveness. They are commonly used in DC power supplies, switch mode power supplies, high-frequency switching and control circuits, AC motor control, and power back-up circuits. The working principle of a film capacitor is based on the polarization of the dielectric film. The positive and negative electrodes of the capacitor are coated onto the plastic film, which acts as the dielectric material. Voltage applied to the capacitor causes a positive charge to build up on one side of the capacitor and a negative charge on the other. This creates an electric field in the dielectric material, which then accelerates the electric charge carriers (electrons) and helps to maintain a certain amount of charge within the capacitor.
