Film Capacitors

Film capacitors consist of a thin dielectric film, which is usually polyester or polypropylene, and contact foils on either side. In order to provide component stability, the dielectric film is impregnated with liquid wax. The contacts are embedded in the wax and are attached to thin metal leads or pins. This forms a cross-section resembling a cross, hence the name ‘ film capacitor’. The contacts are typically arranged in several layers, increasing the surface area and improving the capacitance-to-volume ratio.

BFC237390112 Application Field and Working Principle

The BFC237390112 is a polycarbonate film capacitor that is commonly used to provide excellent electrical performance in applications such as audio, medical, power supplies, and filter circuits. The BFC237390112 has a capacitance ranging from 150pF to 1000pF, and has maximum rated voltage up to 250 volts. It features low ESR values, which are typically less than 6 ohms, and low dissipation factors, making it well suited for high frequency circuit designs.

The BFC237390112 combines a high capacitance in a small volume. It consists of two plates separated by a dielectric. When connected to a power source, the plates act as opposite charges, creating an electrostatic field between the plates. When an AC current is applied across the capacitor, the electric field between the plates fluctuates depending on the polarity of the AC current. As this happens, a current flows through the capacitor, which is called a capacitance current. This current creates a phase difference between the applied current and voltage, leading to an energy storage and transfer within the capacitor.

The BFC237390112 is able to provide excellent electrical performance across a wide range of frequencies, making it suitable for use in a variety of applications. Additionally, it is highly reliable and is able to withstand high temperature ranges, making it ideal for use in high-stress and high-temperature environments. Lastly, the BFC237390112 is also highly compatible with surface-mount technology (SMT) which allows for a highly streamlined manufacturing process.
