Film capacitors are a type of capacitor that use plastic film materials as their dielectric. They are electrostatic (non-polarized) capacitors and exhibit generally favorable parameter stability and loss characteristics compared to other types of capacitors. A wide range of construction and material variations exist for film capacitors, making them adaptable for various purposes. They can be used in small-signal applications, where ceramic capacitors are typically used, as well as in power applications where electrolytic capacitors are commonly employed. Film capacitors have found extensive use in electronic circuits and systems, including in audio equipment, televisions, computers, industrial control systems, and many other applications. They offer a flexible and versatile option for circuit designers and engineers due to their favorable characteristics and adaptability. In summary, film capacitors are a type of capacitor that utilize plastic film materials as their dielectric. They are electrostatic capacitors with generally favorable parameter stability and loss characteristics compared to other types of capacitors. They are adaptable for various purposes, from small-signal electronics to high-power systems, and find use in a wide range of applications in electronic circuits and systems.
