Film capacitors are kinds of capacitors which are made from thin plastic or paper known as dielectric materials. The MKP386M412200JT7 film capacitor is an example within this family and a popular choice for many different industrial applications.

Applications

Thanks to its film dielectric structure, the MKP386M412200JT7 capacitor has a higher heat resistance than a standard metalized film capacitor, making it a suitable choice for multiple high temperature applications. A lower equivalent series resistance (ESR) and leakage provides better energy efficiency, making it great for use within AC rectifier circuits. It is also suitable for voltage stabilization, pulse bypass, and energy storage, as well as being a staple part of the designs of most LED lighting systems.

The MKP386M412200JT7, despite its low capacitance, is able to reduce distortions and overvoltages in audio systems, making it suitable for audio and video applications where pure output is essential. It also provides superior isolation, which makes it a popular choice for instrumentation and electro-mechanical equipment.

Working Principle

The working principle behind the MKP386M412200JT7 film capacitor is the same as all other film capacitors. Thin dielectric film is rolled into a cylindrical shape and wrapped in the metalized foil, allowing for a strong insulated connection between the two electrodes. This creates an electrode/dielectric/electrode sandwich that stores energy proportional to the capacitance.

The two metalized foils act as the capacitor’s electrodes, while the dielectric layer in between them is a non-conductive material which stores the energy while preventing direct current from reaching either side. Both two metalized foils are also separated by either paper or plastic layers, which also act as an additional non-conductive layer.

Unlike ceramic or electrolytic capacitors, the dielectric in the MKP386M412200JT7 is much thinner, which provides a higher capacitance and a lower equivalent series resistance. This means it is able to react faster to changes in the current and voltage, as well as being able to store more charge.

The MKP386M412200JT7 also has a high frequency range, which is a result of its capacitance as well as its dielectric design. This makes it a much better choice for applications which require stability and accuracy over low temperatures.

Conclusion

The MKP386M412200JT7 is one of the most versatile film capacitors on the market, thanks to its high temperature and voltage performance, low equivalent series resistance, and its wide frequency range. This makes it suitable for a variety of applications, including rectifier circuits, LED lighting systems, audio/video systems, instrumentation, and electro-mechanical equipment.
