Film Capacitors

Film capacitors, also known as plastic film capacitors, are formed when thin films of plastic are wrapped around an insulating materials such as paper, ceramics, or metal foil which acts as the dielectric between two metal plates. This is why they are sometimes called ‘dielectric capacitors.’ Film capacitors are used in a variety of applications such as handling high voltages, providing stability, filtering, and power management.

BQ014D0333K

The BQ014D0333K is a film capacitor that has been designed specifically for handling high voltage applications. It is designed with two metalized aluminum foil electrodes and a metallized polycarbonate dielectric. This design allows it to handle up to 16kV DC voltage and 4kV AC. Due to its high voltage capabilities, the BQ014D0333K is often used in power supplies, motor drives, and LED lighting applications.

Working Principle

The working principle of a film capacitor is not very different from that of any other type of capacitor. It works on a basic premise that different materials, when in contact, can either attract or repel each other. This phenomenon is known as “electro-static induction”. When two wires placed parallel to each other are charged with a difference in potential, it will create an electric field between them. If certain materials are placed in between the two wires, such as thin plastic films, it will stop the electric field from passing through, creating an electric charge instead. This is how the capacitor works.

Application Field

The BQ014D0333K is designed to handle high voltage applications. Thus, it is most commonly used in power supplies, motor drives, and LED lighting. However, its high voltage capabilities also make it useful in many other fields. It can be used to suppress electrical interference, provide motor speed control, power high-end audio systems, protect circuits from over-voltage, and create filter circuits.

Film capacitors are an essential component of our modern life. From the simplest of applications, such as providing stability and filtering small electronic signals, to the complex power control of motors and lighting, film capacitors offer reliable and efficient performance. The BQ014D0333K provides a dependable high voltage film capacitor, designed specifically to handle tough applications.
