Film capacitors are essential components in various electronic applications. They are often based on polyethylene-naphthalate and offered with special dielectric materials, which typically feature insulation rated for high- and medium-voltage applications, arc protection and self-healing properties.

The BFC2370FL103 film or polypropylene capacitor is an axial leaded capacitor used in many applications requiring a medium- and high-voltage capability. This capacitor features a voltage rating of up to 2kV, a low dielectric absorption ratio, low temperature coefficient, and long life expectancy.

Generally a film capacitor has two electrodes which are separated by a dielectric layer. The dielectric is usually polypropylene film. The physical structure of the film includes two aluminum/zinc-coated polyester films sandwiched between two layers of polypropylene film. The polypropylene layers act as the insulation between the films.

The working principle of the BFC2370FL103 is based on the property of an electrical field between two electrodes that is proportional to the charge stored in them and the capacitance is the ratio of the energy stored in the device to the voltage applied.

A basic BFC2370FL103 is composed of two discs of configured aluminum and zinc-coated polyester films. A dielectric layer of polypropylene film is placed between the two films. When a voltage is applied to the two films, the electrons are attracted to one of the films, creating a charge.

The voltage and current between the films will then shift in order to maintain equilibrium, creating a capacitance. This capacitance is the ratio of electrical charge stored in the capacitor to the voltage applied.

The BFC2370FL103 can be used in various applications such as power supply management, audio-frequency AC line filtering, high-voltage rectifying systems, radio-frequency power loading and noise suppression networks. Its compact size, low ESR and low energy losses make it suitable for many common applications.

In addition, BFC2370FL103 is also suitable for use in switch mode power supplies as well as resonant power supplies for charging batteries or SMPS for various applications. Its high dielectric strength and its low ESR make it highly efficient and reliable for use with fast rising, high-voltage applications.

In conclusion, the BFC2370FL103 film capacitor is an effective and useful electrical component in many applications requiring high- and medium-voltage capability. The capacitor\'s simple structure and superior features make it suitable for a variety of applications.
