Film Capacitors

The C4AF3BW4680A3LK is a film capacitor, a type of capacitor developed in 1959 that uses either plastic film or Mylar as the dielectric material. These capacitors offer excellent voltage, frequency, and stability characteristics in comparison to other capacitors. They also offer many advantages over other types of capacitors such as ceramic, tantalum, and electrolytic capacitors.

Application Field

Film capacitors are used in a variety of electronic and electrical applications. They are widely used in electronics systems such as communication and power supply networks, instruments and meters, industrial equipment, and consumer electronics. They are also widely used for high voltage power transmission and distribution, in automobiles, and for motor control systems.

Working Principles

The working principle of a film capacitor is that when an electric field is applied between two conductors, an electric charge will accumulate on the surface of the dielectric material. This electric field generates an opposite electric charge of opposite polarity between the two conductors. This opposite charge creates an electric field between them, which causes current to flow through the circuit. This current then produces an electric force that opposes the electric field, which reduces the electric charge accumulated on the dielectric material.

Film capacitors are capable of storing large amounts of energy due to their low leakage current and high insulation resistance. They are also highly reliable, have good stability and are ideal for applications where high voltage is required. They can also be used for pulse power supplies, filtering, voltage regulation, and AC/DC power supplies.

Film capacitors are also ideal for use in applications that require both high voltage and high power. They are able to withstand high temperatures resisting temperature fluctuations, making them the best choice for applications that require high operating temperature.
