Film Capacitors

Film capacitors, also known as polymer semiconductor film capacitors, is a type of capacitor which is composed of two electrodes. In many cases, they are made from metallized plastic film, and by rolling up the film to create a capacitor with a higher capacity. BFC246718683 is a film capacitor with metallized polypropylene film and non-woven glass fabric for dielectric. They are mainly used in ac filtering, disregulation rectifying circuits, high-frequency circuits, electric equipment, communication, lighting and so on.

The working principle of film capacitors is relatively simple. The two electrodes are separated by an insulating dielectric material, and the voltage difference between the two electrodes creates an electric field. The electric field affects the electric dipoles of the dielectric material, causing them to rotate and produce attractive and repulsive forces. This is what produces the electric field that allows electricity to flow from one conductor to the other.

Due to the thin film layer which separates the two electrodes, the capacity of these capacitors remains quite stable. Moreover, they are highly reliable, as the thin film offers excellent heat-resistant and high insulation capabilities. The other properties which make these capacitors popular are their low voltage coefficient, low temperature coefficient, high Q and high self-resonance frequency.

BFC246718683 film capacitor has temperature rating 85℃ and its capacitance value 10μF to 500μF, with wide application in ac filter and switching power supplies. It has excellent insulation performance, extremely low DF and high reliability due to the using of metallized polypropylene film and non-woven glass fabric as dielectric. It also utilizes safety-approved high-precision winding techniques and high-quality metallized capacitors, making it optimum for use in harsh environmental applications.

In summary, film capacitors are a great choice for a range of applications. BFC246718683 has proven itself to be reliable, efficient, and long-lasting. With its excellent insulation performance, high Q and high self-resonance frequency, it is the perfect option for ac filter, disregulation rectifying circuits, high-frequency circuits, electric equipment, communication, lighting and so on.
