Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor that uses electrically isolating plastic film as its dielectric material. This type of capacitor is not polarized, meaning that power can be applied to either lead and be absorbed without damage to the capacitor. Film capacitors are frequently used in high frequency applications since they have an excellent high frequency response, and they are also used to stabilize voltage in power supplies.

BFC233990072 Application Field and Working Principle

The BFC233990072 film capacitor is a type of conductive polymer-aluminum film capacitor. It is mainly used in DC power supply filter, high-frequency signal coupling or recovery, LCD backlight voltage stabilization, and other electronic components.

The BFC233990072 film capacitor is designed with a strong dielectric film made from a combination of aluminum and conductive polymer that has a thickness of no more than 0.02ムm. This type of capacitor has a high capacitance value and can be used for various kinds of electronic components and even in radio frequencies. The entire capacitor has a length of about 6.7 mm and a diameter of about 4.4 mm.

The capacitance of the BFC233990072 depends on the capacitance per unit area (coulombs/m2) of the dielectric film and its thickness. The material of the dielectric film, the size of the capacitor, and temperature affect the capacitance value. The working principles of the BFC233990072 film capacitor can be summarized in 3 steps. First, when power is applied, the electrodes will discharge and create a field between them. Second, the dielectric film will store electrical energy by forming a thin film barrier. Third, the power dissipation will reverse the electric field and the capacitor will return to its "resting" state.

The BFC233990072 film capacitor is a reliable, cost-effective, and versatile type of capacitor, making it a great choice for many electronic components. Its ability to handle high voltages, good temperature stability, and high capacitance makes it ideal for many different applications. From DC power supply filtering to LCD backlight voltage stabilization, the BFC233990072 capacitor’s performance is unmatched.
