Film Capacitors

Film capacitors are a type of electrical capacitors that use a thin polymer film as a dielectric material. These capacitors are characterized by high capacitance, high stability, and wide operating temperature range. They are used in a variety of applications, including filter networks, signal processing, power conversion, power supplies, motor controllers, and audio/video equipment.

The BFC230361154 film capacitor is a non-inductive type capacitor with a small size, high temperature and high humidity, and low loss. It is designed to meet the requirements of high-density mixed signal circuit design.

Application Field

The BFC230361154 film capacitor is suitable for a wide range of applications, including circuit boards for high speed digital, analog, RF, and power supply lines, as well as for high power automotive and industrial control applications. It is also well-suited for circuit boards used in the telecommunications industry, especially those that require a small size, high temperature and humidity grades, and low loss characteristics. As it is non-inductive, it is suitable for high-density mixed-signal circuit designs, as well as power circuits in consumer electronic products. In addition, it can be used in audio/video applications and motor controllers.

Working Principle

The BFC230361154 film capacitor works on the principle of an electrical capacitor, which is an electronic component that stores energy in an electric field. It consists of two metal plates (called capacitor plates) separated by an insulating material called a dielectric material. In a film capacitor, the dielectric material is a thin polymer film, typically made of polypropylene (PP), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), or polyetherimide (PEI). This thin film allows for extremely high-frequency signals to pass through with minimal distortion, and contributes to the capacitors low dissipation factor.

When an electrical charge is applied to the plates of the capacitor, the resulting electric field causes the film to expand against the plates, forming a strong capacitive coupling between them. This increases the capacitance of the capacitor. When the charge is removed, the capacitance decreases and the energy is released back into the circuit.

Conclusion

The BFC230361154 film capacitor is an ideal choice for high performance applications, due to its high temperature and humidity ratings, small size, low loss, and non-inductive characteristics. It is suitable for circuit boards used in a variety of applications, such as high speed digital, analog, RF, and power supply lines, as well as for automotive and industrial control applications. Its working principle is based on the fact that an electric charge applied to the capacitor plates causes the film to expand against the plates, forming a strong capacitive coupling between them.
