Film capacitors are components which are widely used in a variety of industries, and BFC236851274 is one of the most commonly used capacitor types. Film capacitors are designed to offer the capacity and energy storage to power delicate circuits, fulfill diverse requirements, and offer a range of advantages over other capacitor types.

Application Field of BFC236851274

BFC236851274 film capacitors are used in a variety of applications, including audio-frequency filtering, lighting ballast, high-voltage AC power-supply units, power electronic appliances, surge absorption equipment, interference suppression, and noise protections. Film capacitors are also popular in automotive applications, such as onboard high-voltage and low-voltage DC-DC converters for vehicles.

Working Principle of BFC236851274

Film capacitors are designed with electrostatic insulated layers which are encased in a vacuum-sealed container. The two plates of a film capacitor are at a distance of a few micrometers, allowing a uniform electrical field to be set up between them. When a voltage is applied across the two plates, an electric charge is created, generating an electric field.

The dielectric material used in the film capacitor affects its performance, thermal behavior, stability, and durability. As the electric field increases, the capacitance increases to the maximum value determined by the distance between the two plates and the dielectric constant of the material used. As the voltage across the plates increases, the capacitance decreases. This phenomenon is known as dielectric saturation.

Advantages of BFC236851274

The advantages of film capacitors are operating temperature, working life, and low-tollerance. The working life of BFC236851274 can reach up to 20,000 hours which is considerably longer than most other types of capacitors. The operating temperature of this type of capacitor ranges from -40°C to +125°C, making it an ideal component for a variety of applications. Additionally, BFC236851274 has a very low tolerance, meaning that its capacitance values are very precise when compared to other capacitor types.

Film capacitors are known for their excellent high-temperature stability, high-frequency and ripple current capability, non-inductive construction, high voltage rating, and excellent pulse handling capability. Additionally, they are ideal for applications with high-power demands, such as power converters, motor speed controller, welding equipment, and more.
