Film Capacitors

Film capacitors are useful for applications that require an extended stable life, linear and low-loss characteristics, and high dielectric insulation. BFC233840155 film capacitors are no exception and feature a self-healing layer of polycarbonate film that is vacuum-sputtered with silver. This makes them ideal for use in telecom and audio systems such as telephone equipment, audio amplifiers, and radios.

Application Field:

BFC233840155 film capacitors are well suited to applications that require robust and reliable lifetime performance, including signal line motor control, high frequency filtration, power supply circuits, high-energy rectification, and any circuits that involve radio frequency (RF) transmission. Additionally, they can be used as an impedence matching device, in passive filtering, and as a radio signal blocking device.

Working Principle:

BFC233840155 film capacitors work on the principle of the electric double layer capacitor, or EDLC. EDLCs are composed of two very thin layers of film material, one acting as the positive electrode and the other as the negative electrode. A dielectric material such as polycarbonate is selectively applied to the surface of the film material as a sputtered layer of silver. This dielectric layer acts as an energy storage medium and allows electricity to flow between the two electrodes when a voltage is applied.

The way in which BFC233840155 film capacitors work is similar to that of other EDLCs, but with higher operating voltages, lower leakage currents, and better temperature stability. The working principle of the capacitor works as follows: when a voltage is applied to the electrodes, a flow of electrons from the negative electrode to the positive electrode creates an electric field between the two electrodes. This field stores energy in the form of static charges and allows electricity to flow between the two electrodes – which causes the capacitor to release an electrical pulse.
