Working Principle

The KP1830122635 thin film capacitor consists of a thin film of polypropylene, or other dielectric material, which is wound into multiple layers together with its electrodes on either side of the dielectric layer. The electrodes are connected by external conductors, generally referred to as lead wires. When an electric current is applied to the capacitor leads, an electric field is created within the thin film dielectric layer, which stores the electric energy and creates the necessary charge.

The thin film dielectric layer can be either a single layer or multiple layers. The potential difference between two electrodes is determined by the electric field strength. The characteristics like capacitance and voltage ratings depend upon the film material, thickness and the number of layers, as well as the surface area between the electrodes. The capacitance can also be varied by changing the angle of winding or by varying the spacing between the windings, giving the designer a range of possibilities in achieving the desired characteristics.

The KP1830122635 thin film capacitor is designed to exhibit excellent charge and discharge characteristics with high capacitance and low ESR. Some models are also equipped with the highest overvoltage protection capability in the industry and self-healing feature.
