BFC246958393

Film Capacitors

The purpose of the film capacitor, also known as “BFC246958393”, is to store electrical energy and it has many applications. It is especially useful in cases where electrical noise needs to be filtered and/or components require a low self-resonant frequency. This capacitor makes use of a plastic-film dielectric as its dielectric medium and is primarily used in audio-frequency circuits.

Film capacitors feature many benefits over other capacitor types, including excellent insulation, realiability, stability, good operating and storage temperature range, stiffer capacitance with respect to applied voltage, as well as small size and low weight. Their ability to handle high-frequency and transient voltage spikes, as well as maintain their capacitance over a wide temperature range makes them the ideal choice in many applications.

BFC246958393 can be used in a variety of applications, ranging from filters, switch-mode power supplies, tuning, amplifiers and rectifiers, as well as for noise and ripple filtering in consumer and automotive electronics.

Working Principle

The BFC246958393 film capacitor is constructed of two polymer films containing metal particles suspended in a dielectric fluid and two metal leads. Each film is a multi-layer metallized film that has a conductive metal layer sandwiched between two dielectric layers. The metal layer is perforated with intermittent pulses of current and thus creates a “breather” between the two conducting surfaces of the capacitor. This breather allows the electric field to penetrate the dielectric layers, which then induces electrostatic attraction between the two films. This electrostatic attraction produces the capacitance of the film capacitor. The conductive metal layer functions as an electrode, while the dielectric layers serve as barriers to the electric field.

The unique design of the BFC246958393 capacitor allows for the device to have a very low self-resonant frequency and relatively low losses at medium to high frequencies. This low frequency also allows for the capacitor to handle high-current applications without saturating or overloading. In addition, these capacitors are capable of withstanding large transient voltages and remain dielectric even with high temperatures.

BFC246958393 film capacitors are also well-suited for AC applications because of their excellent AC stability. The dielectric film’s characterisitics remain constant even when varying voltage of the alternating current is applied. This ensures that the capacitance of the capacitor remains constant over the range of voltage and frequency.

Overall, BFC246958393 film capacitors offer superior performance for a variety of applications, and are especially useful when high levels of noise or transient voltage spikes are present. Their low self-resonant frequency, low losses at high frequencies, and high voltage tolerance makes them a preferred choice for signal conditioning, filtering, and power-supply applications.
