BFC236922124 Datasheet/PDFFilm Capacitors
BFC236922124 is a film capacitor with good performance whose application field and working principle should be understood to make it better use. Film capacitor is a kind of capacitors whose electrode and dielectric use thin film instead of liquid, the diameter of the film is much thinner than human hair. Comparatively, film capacitor has mini size and small volume, and has low equivalent series inductance, low equivalent series resistance, wide frequency response, high self-healing which make it has a wide application field.
Application Field
Film capacitors could be used in a range of applications that require high performance and variable applications. It is essential in circuit circuits, for example, CRT display circuits, audio frequency circuits and high speed circuits. They are most commonly uesd in filter circuit for energy storage and timing circuits for applications such as timing controlling, auto-motive, circuit protective devices and signal transmission devices.
The semi-conductive metallized film capacitors which combined composite film are widely used in military and aeronautics for being with advantages of low inductance, broadband, low resistance, high pulse capacity and high dielectric constant.
Working Principle
The working principle of the film capacitor is based on electrostatic theory. This type of capacitor consists of two main parts, that are an anode and a cathode. A thin metal layer is formed at the interface between the two layers. This layer is known as dielectric which prevents the electron flow between the electrodes. This process is known as electrostatic storage. The thickness of the dielectric layer determines the capacitance.
When voltage is applied, electrical charges of opposite polarity start to accumulate on each side of the dielectric layer. This stored energy is used to pass current through the capacitor, at which the charge is separated and stored in the dielectric. The energy stored per unit area of the capacitor is known as the capacitance.
Film capacitor have high power density, stable performance, and long working life. They are stable in temperature and humidity. Furthermore, they have no electrolysis and non-polarity. The dielectric of the film capacitor has high insulation and great capability to avoid current leakage.
