Film Capacitors

Film capacitors, also known as plastic film capacitors, are advanced electronic components that use thin, multi-layer plastic film as a dielectric material. They are usually non-polar and operate at higher AC voltage and lower impedance than ceramic and electrolytic capacitors. MKT1820515256 is one of the most popular film capacitors, and its features and applications are widely used in many electronic products.

MKT1820515256 Features

MKT1820515256 is a film capacitor with a maximum rated voltage of 315V. Its capacitance range is from 0.01μF to 0.22μF, and its capacitance tolerance is ±5%. It has a high insulation resistance and is stable in performance. In addition, it also has a small equivalent series resistance (ESR). The MKT1820515256 capacitor has a UL approval, which means that it has a safe and reliable quality.

MKT1820515256 Application Fields

Due to its high reliability, low cost and easy fabrication, MKT1820515256 film capacitors are widely used in many electronics. For example, in audio equipment, they are usually used as decoupling capacitors in power supplies and audio crossover networks. In automotive applications, these capacitors are used for power supply filtering, starter motor noise suppression, etc. In addition, they are often found in home appliances, such as microwave ovens, washing machines, air conditioners, etc.

MKT1820515256 Working Principle

The working principle of MKT1820515256 film capacitor is based on the fact that it has two metal plates separated by a thin plastic film. When an AC voltage with its corresponding frequency is applied between two plates, an electric field is generated inside the film. This results in a series of electric dipoles, each of which creates an opposing electric field. As a result, this electric field is capable of cancelling the applied electric field, thus leading to capacitance. At the same time, the MKT1820515256 capacitor also has a self-healing property, which means that it can recover automatically from minor insulation damage.

In summary, the MKT1820515256 film capacitor is a reliable and widely used electronic component due to its features and applications. It is capable of providing high insulation resistance, low ESR, and good protection against voltage spikes. The working principle of the MKT1820515256 film capacitor is based on electric dipoles and electric fields, which make it very effective in many applications.
