Film Capacitors

Film capacitors, also commonly known as plastic film capacitors, are developed through the use of insulating films made of plastics or organic polymers, such as polypropylene, polystyrene, and polyethyleneterephthalate (PET). These capacitors are suited for applications where stability and effective insulation that can withstand higher reverse and intermittent voltages are desired. Their main advantages over ceramic capacitors or electrolytic capacitors lies in their very wide range of operating temperatures, their excellent stability, and their ability to withstand high-frequency interference.

KP1836127135 Application Field and Working Principle

KP1836127135 is a film capacitor designed for use in the high-voltage, long-term, high-stability applications. Its construction incorporates two layers of a polypropylene substrate, thermally fused together and encapsulated with a resin in order to enclose the capacitor element. This substrate provides an electrical insulation capability that is superior to rival capacitors. The two electrodes of the capacitor are connected to the substrate layers, which serve as the electrical terminals.

KP1836127135 use a special dielectric layer that is constructed of polypropylene and has a low dielectric constant. This special dielectric layer permits the capacitor to handle a high voltage without any reduction in its rated energy storage. In addition, the dielectric constant of this material is unaffected by temperature fluctuations or humidity, and therefore the capacitor has excellent stability over a long period of time.

The working principle for KP1836127135 is fairly simple. When a voltage is applied to the capacitor, an electric field is created between the two electrodes. This electric field causes electrons to move, thus creating a charge separation, or capacitance. As the capacitor continues to be energized, the charge between the two plates builds up, and a difference in voltage between the two plates is established. This voltage establishes the capacitance, which determines the amount of energy that the capacitor can store.

KP1836127135 is suitable for a variety of applications such as medical equipment, sophisticated industrial equipment, and other high-precision instruments where stability and reliability are required. Especially for power supplies, they provide the fast charging as well as the necessary voltage pumping of high-voltage pulses, and often replace electrolytic capacitors as the primary or supporting capacitor in applications as they provide better steady-state current performance and stability.
