Film capacitors, also called plastic film capacitor, are capacitors which have a dielectric consisting of a film of plastic material. The surface of the film is usually coated with a thin layer of metal which forms the electrodes of the capacitor. The film capacitors are often used in high-frequency circuits, in which a capacitor can be selected for its low capacitance signal change and high tolerance. KP1836333205 is an example of these film capacitors, which has various application fields and working principles.

Application Fields: KP1836333205 can be widely used in LCD TVs, DVD players, amplifiers, mobile phones and other electronic components. It provides excellent electrical insulation, shock, and vibration resistance and vibration isolation. As a result, KP1836333205 is suitable for the most demanding applications in consumer and automotive electronics.

Working Principle: The inner structure of the KP1836333205 is composed of dielectric layer with electrodes, shielding backplane and electrode foil. The dielectric layer is formed of multiple layers of a kind of film that has high insulation properties, while the electrode foil is made of an aluminum-based foil with a very thin layer of copper-plated. The dielectric layer and the electrode foil form a parasitic capacitance between them. This capacitance changes with the voltage applied to the capacitor. At a higher applied voltage, the capacitance increases and the current decreases accordingly. At a lower applied voltage, the capacitance decreases and the current increases.

The shielding backplane consists of an insulation material, such as mica or polyester. This material is placed directly behind the electrode foil to provide additional insulation and to reduce interference. The shielding backplane also helps to decrease the leakage current of the capacitor, thus providing a longer lasting and more reliable product.

KP1836333205 provides superior electrical performance, reliability, temperature stability and cost effectiveness in a wide variety of applications. Its unique backplane structure, combined with a thin layer of copper-plated aluminium foil, makes it ideal for use in high-precision, high-speed digital circuitry.
