Film Capacitors

BFC233911153 is a type of film capacitor widely used in electrical and electronic circuits. Film capacitors are very popular due to their excellent characteristics such as low electric leakage, high temperature coefficient and low susceptibility to dielectric absorption. They are ideal for applications in high voltage and high frequency circuits.

Application Field

BFC233911153 film capacitors can be used in a variety of applications, such as audio and video equipment, DC/DC converters, telecommunications equipment, industrial drives, motor control systems, power supplies, computers, inverters, TV, audio amplifiers, and automotive electrical systems.

Film capacitors are primarily used to store and filter energy. They can be used for filtering distortion produced in audio and video circuits, coupled with other capacitors to suppress noise in power supplies, and used to reduce noise caused by power surges and voltage transients in communications. Additionally, they can be used in other sensitive circuitry such as digital switching systems, safety and alarm systems.

Working Principle

BFC233911153 film capacitors are made of an insulating dielectric material, usually polypropylene, which is sandwiched between two metal plates. This dielectric material can be coated with metal foil, or the metal plates can be either etched or pressed to form the electrodes. The dielectric helps make the capacitor more stable and less susceptible to temperature changes. As with all capacitors, the amount of charge that can be stored between the metal plates depends on the dielectric constant of the material and the area of the plates.

The working principle of a film capacitor is based on the capacitance of the material between the electrodes. When a voltage is applied, electrons collect inside the film insulator. This creates a dielectric field between the electrodes, and this field also produces an opposite voltage, which acts to oppose the voltage applied to the capacitor. This is known as capacitive reactance, and the amount of this reactance depends on the dielectric constant of the material and the area of the plates.

The capacity of a film capacitor also depends on the thickness of the dielectric material. The thicker the dielectric material, the higher the capacitance and the greater the amount of energy it can store. This makes film capacitors highly efficient and ideal for applications in high-frequency and voltage circuits.

BFC233911153 film capacitors are highly regarded for their low ESR, high insulation resistance, and high dielectric absorption. They have low parasitic inductance and minimal dielectric losses, making them ideal for applications in high-dissipation electronic circuits.
