Film capacitors are a type of capacitor, consisting of one or more thin layers of metal overlaid with plastic film, which stores electric charge and provides capacitance and electrical insulation. Due to their excellent stability and superior electrical characteristics, they are widely used in diverse fields such as consumer electronics, automotive, medical, industrial electronics, telecommunications and audio. In this article, we will discuss the application field and working principle of the MKT1820347104 model of film capacitors.

MKT1820347104 is a kind of stacked metallised polypropylene film capacitor with high working voltage. It is characterized by low dissipation factor, high insulation resistance and good self-healing functions. The capacitance of this film capacitor ranges from 1μF to 2.2μF with an operating temperature ranging from -55°C to 85°C.

As mentioned earlier, MKT1820347104 film capacitors are commonly used in a variety of applications due to their superior electrical characteristics. For instance, the capacitors are often used in the control and power supplies of photovoltaic solar cell inverters and are also employed in switch mode power supplies of digital TVs, radios, microwaves, computers, and other domestic appliances. Additionally, they are employed in the high-frequency circuits of telecom stations and cables as well as in dynamic filters in general automotive systems.

The working principle of this kind of film capacitor is based on electrostatic induction. Each capacitor is comprised of two electrodes which are surrounded by a dielectric layer. This dielectric layer is formed from polarised molecules which are attached to the metal electrodes and create a static electric field. As current flows through the circuit, one electrode is positively charged and the other is negatively charged. The dielectric material is a insulator which prevents the flow of current from one electrode to the other. Therefore, when a voltage is applied to the capacitor, it stores charge as its electrons build up or decrease against the negative or positive charge of the other electrode.

The main benefit of the creation of this electric field is that it can store electric charge and be used to provide a steady voltage. This is often used in switch mode power supplies and amplifiers. The electric field created by the MKT1820347104 film capacitor also allows electrical current to pass through the dielectric material, adding to the efficiency of the circuit as a whole.

In conclusion, MKT1820347104 film capacitors are widely used in electronics due to their excellent stability and superior electrical characteristics. Their working principle is based on electrostatic induction which allows them to store electric charge and provide a steady voltage. They are suitable for use in many applications including photovoltaic solar cell inverters, switch mode power supplies of digital TVs, radios, and other domestic appliances, as well as high-frequency circuits of telecom stations and cables, and dynamic filters in general automotive systems.
