Film capacitors, also known as Polyester capacitors, are well-known electronic components of the electronic industry. R46KN322000M1M is a type of film capacitor. It has a variety of application fields and working principles. This article will discuss them in detail.

Application Field

The R46KN322000M1M film capacitor is applicable to high precision equipment with high insulation requirements, such as telecommunications, industrial frequency inverter, medical, military and various high-end products.

These capacitors can be used to filter, snub, bypass or couple AC or DC signals in electronic circuits, as well as suppress surge voltage or acting as voltage-dropping components. These capacitors can also be used in AC motors and AC motors.

Working Principle

The R46KN322000M1M film capacitor is made of polyester film as a dielectric and aluminum oxide as an oxide film. During the manufacturing process, a thin layer of aluminum oxide is formed on the surface of the polyester film as the capacitor dielectric. Then, a pair of metal electrodes are formed on its two sides, forming a series of very thin metal and dielectric layers. When an alternating current is applied, the polyester film will be alternately charged and discharged, forming an AC current on the surface of the polyester film.

In order to reduce the loss of current, a Metal-Oxide-Film (MOF) layer is added between the electrodes. The MOF layer can improve the insulation characteristics of the capacitors, reduce leakage current and increase the reliability of its performances. The MOF layer is also one of the features that make the capacitors a ideal choice for AC motors and AC motors.

Conclusion

In conclusion, the R46KN322000M1M film capacitor is an ideal electronic component for a variety of applications, especially AC motors and AC motors. Its working principle consists of a polyester film as the capacitor dielectric, a metal-oxide film layer as insulation and a pair of electrodes as current conducting elements. This makes the capacitors highly reliable, increasing the life of the product.
