Film Capacitors

A film capacitor, also known as a plastic film capacitor, is part of an electrical circuit that is designed to store energy and to discharge it. It is an electrical component that includes two thin metal plates separated by a dielectric layer that can store an electric charge. This dielectric layer is made of an insulating non-conductive material such as plastic, ceramic, heat-resistant paper, or fiberglass. The thickness of the dielectric layer determines the capacitance of the film capacitor, which is the amount of electrical energy it can store and release.

BFC236958223 is a modern type of film capacitor designed for industrial and military applications. The BFC236958223 film capacitor is made of a PPS/PC/PPS composite material with an integrated E-shield layer that makes it highly resistant to electrolytic stress and extreme environmental conditions. It has a wide capacitance range of 0.22 μF to 12 μF with ±5% capacitor rating accuracy.

Application Field & Working Principle

The BFC236958223 film capacitor is used in applications that require high stability electric fields, as well as in high power switch mode power supplies. Its unique construction provides excellent reliability, reduced EMI, and low dielectric absorption, making it suitable for applications such as power management, data and signal processing, frequency control, and energy storage.

The working principle of the BFC236958223 film capacitor is simple. When a potential difference is applied between the two plates, a static electric charge is built up on each plate, producing an electric field between the plates. The size of the electric field will depend on the amount of charge, which in turn is determined by the amount of voltage applied between the two plates. When the capacitor is connected in an AC circuit, the voltage across the capacitor will change with each cycle, causing the internal electric field to expand and contract in an alternating fashion. This creates a current that flows into or out of the capacitor and is proportional to the strength of the electric field.

In addition to its excellent stability and reliability, the BFC236958223 film capacitor is also known for its low levels of EMI interference, as well as low dielectric absorption. This makes it suitable for a variety of industrial and military applications, including high-power switching modes, motor speed control, and frequency control.
