MKT1820618165 Application Field and Working Principle

Film capacitors are an important type of capacitor with a distinct working principle and application field. The MKT1820618165 is a specific type of film capacitor that is the focus of this article. This capacitors main function is to reduce the amount of voltage needed to reach a necessary level when powering certain mechanical applications.

When talking about film capacitors, we are referring to the use of thin plastic films as the dielectric for a capacitor. Film capacitors have a high dielectric strength relative to other types of capacitors, making them useful when storing energy with a small size. The MKT1820618165 specifically is a type of metallized polyester film capacitor.

Polyester film capacitors are a specific type of film capacitor and they are made by coating a polyester film dielectric with a type of metallic coating. When an electric current is applied, an electric field is formed causing charges to polarize and cause an opposing electric field to the original. This resulting electrical force in the capacitor is what is used to reduce the voltage needed to reach a certain level.

MKT1820618165 capacitors are typically used in a variety of different mechanical applications such as AC power supplies, engine rotation speed regulated systems, DC motor speed control, air conditioners, printing equipment, and remote controller power systems. When a DC voltage is applied to the terminal of the capacitor, air-core transformers are generated and enter into resonance in a very short period of time. This resonance creates an alternating current circuit with a slow voltage rise time, reducing the amount of power needed to reach a set voltage.

MKT1820618165 film capacitors work by manipulating the voltage levels to reduce the total amount needed. Specifically, by increasing the capacitance of the capacitor while reducing the size of its material, these capacitors are able to optimize the current create a higher “sweet spot” voltage level in the power system. This feature is especially important in mechanical applications where precision is a requirement.

In summary, the MKT1820618165 is a type of metallized polyester film capacitor that is used in a variety of mechanical applications. It works by manipulating the voltage levels by increasing the capacitance of the capacitor while decreasing its size, resulting in a higher "sweet spot" voltage level in the power system.
