Introduction

Film capacitors are widely used in industrial and consumer applications, and are characterized by reliable performance, high thermal stability and long life. MKT180515404 capacitors are polyester film capacitors, as one of the popular technology in film capacitors, is particularly suited for AC mains filtering, switch mode power supplies, high-end audio, interference suppression and other general electronic applications. In this article, the application fields and working principle of MKT180515404 will be discussed in detail.

Application Fields

MKT180515404 capacitors are designed to withstand high currents and voltages, making them ideal for AC mains filtering, switch mode power supplies, and other high power applications. Due to their excellent temperature stability, they are also suitable for use in environments where the temperature may vary significantly, such as in outdoor applications. In addition, MKT180515404 capacitors are also commonly used in audio applications, providing excellent suppression of audio noise and other electronic interference. The capacitor’s large capacitance values, its low inductance, as well as its high discharge and charging capabilities make it especially well suited for use in audio applications. Furthermore, because of its high dielectric absorption, it is also suitable for use in special applications, such as anti- interference protection.

Working Principle

MKT180515404 capacitors are made of polypropylene film and aluminum foil electrodes. The capacitor consists of two aluminum foil electrodes that are separated by a dielectric material. The film material used for the dielectric layer is typically polyester. The thickness of the dielectric layer is very thin, no more than several microns. The capacitor works by storing excess electric charge. When the voltage on the capacitor exceeds the voltage rating of the capacitor, it will prevent current flow. The dielectric material in the capacitor acts as an insulator and prevents current from flowing through it. The capacitor is connected to the circuit in order to store and release electric energy. When an AC current is passed through, the capacitor is charged. When the cycle of the AC current changes, the capacitor is discharged and the current is regulated. The process is repeated continuously and thus the capacitor helps to regulate the voltage in the circuit.

Conclusion

In conclusion, MKT180515404 capacitors are ideal for a wide range of industrial and consumer applications. They are well suited for AC mains filtering, switch mode power supplies, high-end audio, interference suppression and other general electronic applications. The capacitor is made from polyester film and aluminum foil electrodes, and its working principle is based on storing electrical energy and then releasing it as needed.
