Film Capacitors

Film capacitors, also known as plastic film capacitors, are constructed with a polymer film laminated with metal electrodes. This type of capacitor is an important electronic component for many applications, such as bypass filtering, AC coupling, signal smoothing and stable voltage averaging. This article will discuss the application field and working principle of the BFC237885103 film capacitor.

Application Field

The BFC237885103 film capacitor offers a wide range of applications, making it a popular choice in many consumer and commercial electronics. It is commonly used for AC couple in a wide range of consumer electronics, such as televisions, radios, and computers. This capacitor is also used for signal smoothing in medical equipment, as well as in audio and motor drive amplifiers. In addition, this capacitor is also used for AC filter or harmonic filter in power electronics, mobile electronics, and home appliances.

Working Principle

The BFC237885103 film capacitor has an operating voltage of 440Vac and a capacitance of 0.015uF. It is constructed with a flexible polypropylene film and a metal electrode to act as two plates of a capacitor. This capacitor works by blocking DC signals while allowing alternating signals to pass through freely. It works in the same way as any other capacitor, in which a voltage is applied to the plates, which generates an electric field between them. This electric field stores energy and creates a capacitance.

When an alternating current is applied to the capacitor, the electric field between the plates fluctuates with each cycle of the current, allowing the alternating current to pass through the di-electric material more easily than a DC current. This allows the capacitor to act as a low-pass filter, blocking high frequency signals while allowing lower frequency signals to pass.

The BFC237885103 film capacitor can handle a wide range of voltage and current, making it a reliable and efficient choice for a variety of applications. It is highly flexible and resistant to most environmental conditions, making it a durable long-term component that can outlast its ceramic or electrolytic alternatives.

Conclusion

The BFC237885103 film capacitor is a versatile and reliable component that can be used for a variety of applications. It is constructed with a flexible polypropylene film and a metal electrode to act as two plates of a capacitor, allowing for DC signals to be blocked while allowing alternating signals to pass through freely. It is resistant to most environmental conditions and can handle a wide range of voltage and current, making it an ideal choice for many consumer and commercial applications.
