Film Capacitors

BFC246959272 film capacitors are types of electrolytic capacitors which are made from thin plastic film. There are two types of these capacitors – general purpose film capacitors and high reliability film capacitors for mission-critical applications. Because of their size, these capacitors have high dielectric constant and possible high energy density and are suitable for use in a wide variety of applications.

Application Field

The most common uses of BFC246959272 film capacitors are in AC/DC power supplies, in power line filtering and decoupling, and in EMI/RFI suppression. These capacitors are also often used in high voltage rectifiers, resonant circuits and switching power supplies. These are also used in high frequency circuit filtering, stability, UPS, digital and analog signal processing, and medical care equipment.

Working Principle

BFC246959272 film capacitors use an example of a capacitive element which is based on the principles of electrostatics. The dielectric material used in these capacitors is made from a thin plastic film. The conductors are then set up in a co-planar geometry and connected to the external terminal of the capacitor. This allows the capacitor to store electrical energy, when there is a potential difference across the Conductors. When current is applied to the capacitor, electrical charge starts to flow and is stored on the capacitor’s plates. This creates a capacitance, the amount of electrical energy stored in the unit, which is dependent on the size of the capacitor plate and the dielectric strengths of the material used.

Advantages

Due to their thin plastic film structure, BFC246959272 film capacitors are temperature stable, and can be used at a wide range of temperatures. They also have lower ESR, which makes them ideal for use in high frequency applications. Furthermore, these types of capacitors are self-healing, which means they can withstand surge currents without any damage to the components. Additionally, they have very low leakage currents, which makes them suitable for precision circuit design.
