What Are Film Capacitors?

Film capacitors are part of a family of electrical components known as capacitors that provide power when connected to an electrical circuit. A film capacitor is a type of variable capacitor made with a dielectric layer made of a insulating material such as polyester or polypropylene plastic film that is rolled into a cylindrical or rectangular shape.

What Does B32922C3823K189 Film Capacitor Do?

B32922C3823K189 is a film capacitor. It is a non-electrolytic, metallized polyester film capacitor. It has excellent insulation, high current load and low ESR; its applications are specialized.B32922C3823K189 is used in automotive EMI component and other professional applications. It reduces the EMI and spike noises generated by the automotive ECU. This prevents the interference of the noise source from disturbing the surrounding environment, creating a strong and reliable system.

The Application Field and Working Principle of B32922C3823K189 Film Capacitor

B32922C3823K189 Film capacitor is widely used in vehicles, automotive applications and professional industries. It is well suited for applications involving short high-frequency blocks such as anti-interference devices for electronic control units (ECUs), communication modules, sensors and switches. The working principle of the B32922C3823K189 film capacitor is that when the capacitor is connected to an AC current, the electric field is produced on one side of the insulating film and the electric field on the other side is equal in magnitude but opposite in polarity. This creates an electric field inside the film. The electric field creates an attraction between the molecules of the film, storing energy in the form of an electrostatic field. The capacitors is able to store this energy until the power is disconnected from the circuit. Film capacitors can also be used to filter out high frequency components of a signal. This is achieved by connecting a series of capacitors in parallel with the signal source. This arrangement is typically referred to as a low-pass filter, and is commonly used to reduce interference in a signal. In contrast to other types of capacitors, film capacitors do not feature an electrolytic fluid. Film capacitors are also known as flat-plate capacitors because of their flat, planar design. This is in contrast to other capacitor designs, such as the cylinder capacitor, which features a cylindrical design.

Conclusion

The B32922C3823K189 film capacitor is a specialized capacitor used mainly in automotive applications, due to its low ESR, high current load, and excellent insulation. Its working principle is based on the electric field between the terminals of the capacitor, which stores energy in the form of an electrostatic field. It is also commonly used in professional applications such as anti-interference devices for ECUs, communication modules, sensors, and switches.
