Film Capacitors

Film capacitors, also known as film dielectric capacitors, plastic film capacitors, polymer film capacitors, and foil capacitors, are one of the earliest types of capacitors. They are made by sandwiching a thin plastic film between two metal plates, which create a rectangular plate capacitor. The capacitor works by using the polarization of the molecules of the film to oppose the electric field. This leads to a decrease in electrical current, resulting in an efficient capacitor being constructed.

Features of Film capacitors

Film capacitors have some advantages over other types of capacitors. One of the main advantages is that they have a wide temperature range. They have high vibration resistance, and they can have a variety of shapes and sizes, making them suitable for all types of applications. Additionally, they have excellent linearity and predictable capacitance over time.

BFC237229474 application field and working principle

BFC237229474 films are metalized plastic films, and they are used to construct capacitors. They are used in applications such as filtering, motor control, medical, and communications. BFC237229474 films are specifically designed for applications requiring extreme temperature ranges and high performance. These films are composed of a combination of polyethylene terephthalate (PET) and a mixture of inorganic insulating materials.

In a BFC237229474 capacitor, a thin metallic aluminum layer is vacuum-deposited onto the film and provides the opposing pole for the electrical charge. When a voltage is applied across the conductor, an electric field is induced in the field increasing and producing a capacitance in the capacitor. The amount of capacitance depends on the dielectric constant of the film and the thickness of the metal film.

Benefits of BFC237229474 films

BFC237229474 films have a wide temperature range, so they are suitable for applications in extreme environments. They have excellent linearity and high precision, which makes them suitable for measuring devices. Additionally, they have a low ESR (equivalent series resistance) and a high insulation resistance, so they are well suited for noise suppression. They also have a long operational life and a low leakage current, making them ideal for high frequency applications.
