Film Capacitors

Film capacitors are a type of capacitor that is typically constructed with an organic dielectric material such as polypropylene, polycarbonate, or polyesters. They are characteristically more reliable and smaller in size compared to the traditional electrolytic capacitors. A Film capacitor is rated by its capacitance, rated voltage, and the temperature range in which it is designed operating. The MKP1839315255G capacitors are designed for applications in switch mode power supplies, as signal filtering, and for general DC blocking.

Working Principle

Film capacitors are constructed from a few basic components. This includes an anode, a dielectric layer, and a cathode. When an electrical current is applied to the capacitor, an electric field is created between the plates. This electric field causes a shift in the dielectric layer in proportion to the applied voltage. This results in a change in the capacitance of the capacitor, which can be used to store and control electrical charge. The basic principles behind a film capacitor are similar to those of other types of capacitors, such as the electrolytic, ultracapacitors, and ceramic types. However, due to the films dielectric material, film capacitors are more efficient at storing energy and have a higher rated temperature range than other capacitors.

Application Field

The MKP1839315255G film capacitors are designed for general DC blocking and signal filtering applications. They are used in many devices such as computers, cell phones, and TVs. They are also commonly used in power supplies, such as switching power supplies for modems and routers as surge and inrush current blocking. The film capacitor technology also allows them to be used in other applications. For example, they can be used as AC filters, RF choke coils, and surge suppressors. They are also used in automotive and medical applications, in direct current motor control applications, and in HVAC systems.
