Film capacitors, or plastic film capacitors, are electrical energy storage devices composed of two metal electrodes, held apart by a thin plastic film. The film capacitor uses a dielectric film, typically polyester, polycarbonate, polypropylene, polystyrene, or polyester-imide, to store electrical charge. These film capacitors have many advantages over traditional electrolytic and ceramic capacitors: greater insulation resistance, higher operating temperature ratings, improved tolerance for high humidity and high frequency applications, and excellent linearity, stability, and reliability. Commonly used in AC line straining and for filtering applications, film capacitors protect high voltage AC power circuits from large potential momentary currents. BFC237944135 is one example of a plastic film capacitor.

One of the primary application fields for the BFC237944135 film capacitor is in AC line straining and power DC conversion. This capacitor is equipped with a rating of 100VAC (RMS) and can handle a maximum voltage of 120VAC and a maximum operating temperature up to 85°C. It is also designed with 6mm x 11mm dimensions, allowing for easy installation across a broad range of industrial and commercial applications. Moreover, it has a rated capacitance of 0.010µF and a leakage current of less than 0.2µA.

The working principle of the BFC237944135 film capacitor lies in its dielectric core. As an AC current is supplied to the capacitor, the core material polarizes and provides a charge booster, allowing it to store electrical energy. The charge booster effect results from the induction of the film dielectric, which in turn produces a potential difference between the capacitor’s electrodes and causes an electrical current to be supplied to the capacitor. This electrical current allows the capacitor to store electrical energy, which it then releases when the current is removed.

The BFC237944135 film capacitor also features a low parasitic inductance and resistance, making it ideal for applications that require a very high frequency response. This capacitor is hermetically sealed and features integrated overvoltage protection, making it suitable for use in high-voltage environments. Additionally, its very low resistive impedance reduces power dissipation, making it a reliable and efficient choice for power conversion applications.

The BFC237944135 plastic film capacitor is an exemplary example of a film capacitor designed for industrial and commercial applications. With its consistent performance and exceptional reliability, it is suitable for applications such as AC line straining, DC power conversion, and high frequency applications. Its hermetic sealing, low parasitic inductance, and low resistive impedance make it well suited for demanding, high voltage environments.
