Film capacitors, also known as plastic film capacitors, refer to a kind of capacitors based on plastic film as dielectric materials. In order to ensure the insulation effect, the plastic film is usually coated with an insulating metal layer on both sides. The capacitance of this type of capacitor is relatively small, usually ranging from microfarads to decoupling capacitance. B25834C226K4 is a kind of film capacitor, and it has a wide range of application and can greatly improve the power stability and noise reduction.

The B25834C226K4 is a film capacitor with the metallized polyester film as the dielectric and copper foil as the electrodes and is designed for use in AC or DC circuits. This film capacitor features excellent performance in low impedance, low loss, low ESR, small leakage current and high frequency characteristics. Its capacitance range is from 0.68uF to 223uF, with a voltage range from 250VAC to 1500VAC.

B25834C226K4 has a wide range of application fields, such as lighting equipment, electronic control systems, industrial instruments, alarm systems, UPS, electronic ballasts, amplifier circuits, DC temperature controllers, AC motors, inverters and other electronic devices. In these applications, B25834C226K4 can be used to provide “anti vibration” limitation, high frequency filtering, noise suppression, and play the role of decoupling.

In terms of structure, B25834C226K4 is a three-layer film capacitor, which consists of a metallized polyester film, an aluminum oxide film, a thin dielectric aluminum oxide film, and a copper foil electrode. The metallized polyester film is selected as the dielectric of B25834C226K4, which has a dielectric constant of 3.2 and an insulation breakdown voltage of 11KV. With this unique structure, B25834C226K4 has a higher breakdown voltage and higher insulation resistance than ordinary film capacitors.

In terms of the working principle, B25834C226K4 works according to the principle of dielectric absorption. Under the application of certain voltage, an electric field will be generated between two electrodes, and then absorbed by the dielectric. At this time, electric energy will be stored in the dielectric and accumulate, forming a static electric charge. At the same time, a certain capacitance will be generated between the two electrodes.

With the wide application field and unique working principle, B25834C226K4 film capacitor has become the ideal choice for many industries. Therefore, it is widely used in various electronic products. In addition, this capacitor has strong high temperature tolerance, moisture resistance and solid insulation characteristics, which make it higher performance than other types of capacitors.
