Film Capacitors

A film capacitor, also known as "plastic" or " polyester film capacitor" is an electronic component. It is made by winding two layers of dielectric film with electrodes contacting the surface. The two electrodes may be in the form of flat layers, with a porous or impregnated layer providing a path from the conducting electrodes to the termination.

Film capacitors are widely used in electronic circuits due to their effect on the frequency response of the device. For instance, in the production of audio amplifiers, film capacitors are often used in the audio signal path. This is due to their ability to reduce high-frequency noise generated within audio amplifiers. Furthermore, film capacitors are used in AC/DC power supplies, as well as in the signal path of a wide variety of consumer electronic devices.

KP1830210013D Application Field and Working Principle

KP1830210013D is a high-frequency plastic film capacitor. It is ideal for applications such as SMD/DIP/remote-controlled type applications. It is rated for operating temperatures up to 125 degrees Celsius, and can be used in lines with voltages up to 250V.

The basic working principle of film capacitors is that two conductors separated by a dielectric material create an electric field which stores energy in the form of charges. The dielectric material is normally a plastic film, or sometimes ceramic, paper or other substances. This dielectric increases the capacitance, or capacity of the capacitor. The capacity of the capacitor is determined by the ratio of the dielectric material\'s surface area and the length of the separator.

The high-frequency properties of KP1830210013D are superior to those of common polyester film capacitors. This allows for faster charge and discharge times, as well as better electrical efficiency. This makes it well suited for applications where fast switching speed is required.

KP1830210013D is also designed to be especially resistant to damage due to surge currents. The dielectric is coated with a proprietary non-inductive element, which provides very low impedance, and thus greater protection during surge or transient conditions.

Overall, this makes the KP1830210013D an excellent choice for a wide range of applications where high-frequency performance and superior surge protection are desired.
