Film capacitors are one of the more common types of capacitors used in electrical engineering. The main benefit of film capacitors is their high insulation resistance, which makes them ideal for high-voltage applications. The MKT1820639255 is one such type of capacitor, and its application field and working principles are described briefly in this article.

The MKT1820639255 is a high-voltage capacitor designed for use in AC circuits. The capacitance of the MKT1820639255 is 105μF and its rated voltage is 630V or 400V. The MKT1820639255 is typically used in power supply circuits, motor drive circuits, lighting circuits, high-voltage circuits, audio circuits, and other types of AC circuits.

The working principle of the MKT1820639255 is similar to that of other types of capacitors. When a voltage is applied across its terminals, the capacity of the capacitor will store some of the energy supplied. This energy is then released as the voltage rises and falls. The amount of energy that the MKT1820639255 can store depends on its capacitance, which is measured in farads (F). The higher the capacitance, the more energy the capacitor can store.

The MKT1820639255 is a polyester-based film capacitor which means it is non-polarized. Its dielectric strength is 800VAC/DC with an operating temperature ranging from -40°C to +85°C. It also features a ripple current of 1.2Arms and a temperature coefficient of 2000ppm/°C. The MKT1820639255 also has an insulation resistance of 400MΩ minimum.

The MKT1820639255 is ideal for high-voltage and high-current applications such as power supplies, lighting circuits, motors, and audio circuits. It is also very reliable and can withstand short-term power surges without being damaged. The high insulation resistance of the MKT1820639255 also makes it a good choice for high-voltage AC circuits.

In conclusion, the MKT1820639255 is a high-voltage capacitor designed primarily for use in AC circuits. Its rated voltage is 630V or 400V and its capacitance is 105μF. It is non-polarized and features a ripple current and temperature coefficient of 1.2Arms and 2000ppm/°C respectively. The MKT1820639255 is often used in power supply circuits, motor drive circuits, lighting circuits, high-voltage circuits, audio circuits, and other types of AC circuits due to its high insulation resistance and reliable performance.
