Film capacitors are one of the most widely used capacitors due to their good performance, long life and relatively low cost. In this article we will discuss the application field and working principle of the 473MMR400K film capacitor.

Film capacitors are widely used for AC power supply applications, such as filter circuits, power factor correction circuits and energy storage circuits. These capacitors can also be used in oscillation circuits, timing circuits, pulse circuits and rectification circuits. The 473MMR400K film capacitor is specifically designed for use in high-frequency, high-voltage and high-power applications, such as radio and television broadcasting systems.

The 473MMR400K film capacitor is a metalized polyester film capacitor. It is constructed using a thin layer of metallicized polyester film that has been rolled up into a tightly wound coil. This provides the capacitor with superior dielectric properties. The 473MMR400K capacitor also features a metalized anode and cathode, which allows it to store and release energy quickly. This makes it an ideal choice for high-frequency and high-power applications.

The 473MMR400K film capacitor has a maximum operating temperature of 105°C and a maximum voltage rating of 400KV. It has a wide frequency range from 20KHz-200KHz, and it has a high power dissipation capability. This makes it perfect for use in high-power applications such as radio and television broadcasting systems.

The working principle of the 473MMR400K film capacitor is very simple. When AC voltage is applied, the metalized polyester film stores energy and the metalized anode and cathode release it. This alternating current will induce an electric field, causing the electrons to flow back and forth between the capacitor and the external circuit. This flow of electrons is what creates current in the external circuit, allowing devices powered by the capacitor to operate.

In conclusion, the 473MMR400K film capacitor is a high-quality, high-performance capacitor that has a wide range of applications. It is specifically designed for use in high-frequency, high-voltage, and high-power applications such as radio and television broadcasting systems. It has a wide frequency range, a high power dissipation capability, and a maximum operating temperature of 105° C. The simple and efficient working principle of the 473MMR400K film capacitor makes it a reliable and durable component, perfect for any high-power application.
