Film Capacitors

Film capacitors, also known as film dielectric capacitors, are a type of capacitor that uses thin dielectric material, often a film, to store energy in an electrostatic field. Both polypropylene and polyester (PET) are the most common dielectric film materials in use today. Structurally, film capacitors typically feature two electrodes between which the dielectric film is sandwiched.

BFC237545182 Application Field and Working Principle

The BFC237545182 is an industrial-grade capacitors designed to be used in demanding applications such as motor drives, process control and instrumentation, high-frequency circuits, communications equipment, alarm systems, and so on. It is an axial-lead capacitor with a dielectric film that offers high capacitance and dielectric strength, excellent temperature stability, and superior frequency response.

The working principle of the BFC237545182 is that it stores energy in an electrostatic field using a dielectric film. When a voltage is applied across the capacitor electrodes, electric charges build up on both sides of the dielectric. This creates an electrostatic field between the electrodes, which stores energy. The magnitude of this stored energy is determined by the capacitance value of the capacitor.

The dielectric material used by the BFC237545182 is a high-quality polyester film which is many times thinner than traditional electrolytic capacitors. This allows the capacitor to operate at higher frequencies and to have a much lower leakage current than electrolytic capacitors. The BFC237545182 also features industry-leading performance at extreme temperatures, boasting high dielectric strength and low temperature coefficient.

The construction of the BFC237545182 is very rugged and reliable, making it suitable for applications where vibration and shock can be encountered. The lead wire base is sealed with a thermally bonded coating which protects the capacitor from moisture and humidity, thus ensuring a long service life.

In summary, the BFC237545182 film capacitors offer superior performance in demanding applications, with an industry-leading combination of high capacitance, high dielectric strength, low temperature coefficient, and low leakage current. The construction is rugged and reliable, making it suitable for use in extreme temperature and vibration environments.
