Film Capacitors

Film capacitors are designed to provide maximum service life and a rich assortment of features. Many film capacitors, such as the KP1830122015W, are designed for specific applications in the industrial, commercial and military markets. The technology of film capacitors is based on the application of polymeric films and some other high quality dielectrics as the basic medium for storing electrical energy.

Applications of KP1830122015W

KP1830122015W is a high voltage, high current rating, moisture, saltwater and chemical resistant film capacitor designed for use in a variety of applications. It can be used in medical devices, security systems, marine and off-shore equipment, energy storage equipment, automotive electronics, solar panels, and communication devices, among others. It can also be used in military and aerospace electronic systems due to its extreme ruggedness and high frequency performance.

Working Principle of KP1830122015W

KP1830122015W is a three layer film capacitor that works on the principle of electrostatic capacitance. It is comprised of two parallel conductive metal plates separated by a dielectric film. These two plates and dielectric film form an electrical circuit when a voltage is applied and electrical current is conducted between them. The electrical current flows through the capacitor which charges the plates and consequently creates an electric field.

The amount of charge stored in the film capacitor is determined by the size of the plates, the distance between the plates and the dielectric film’s permittivity. The dielectric film determines the size of the electric field and thus its charge. When more charge is added to the capacitor, the charge stored in the film increases as well. The increasing charge in the dielectric causes the electric field to become stronger which increases the current. As a result, the capacitor can store more charge and conduct more current.

Conclusion

KP1830122015W is a high capacity capacitor intended for a variety of applications in the industrial, commercial, and military markets. It works on the principle of electrostatic capacitance and is rated for high voltage, high current, and extreme ruggedness. Its components, such as polymeric films and high quality dielectrics, make it a reliable long-term solution for many electronic systems.
