Film capacitors are electronic components that are widely used in many electrical and electronic applications. The MKT1820647015 is a type of film capacitor that is designed to provide an extremely low profile and high temperature performance. This article will discuss the application field and working principle of the MKT1820647015.

Application Field

The MKT1820647015 can be used in a wide range of applications, including AC/DC motor drives and control, switch-mode power supplies, high frequency filtering applications, resonant circuits, noise suppression, pulse power applications, and EMI/RFI suppression. In addition, it can also be used in automotive, avionics, industrial controls, energy storage, and high power applications.

The MKT1820647015 is designed to provide high performance in a wide range of operating conditions. It is constructed with high-temperature polypropylene film and has a low profile of just 10.2 x 7.1 mm. The capacitor is rated to work with voltage up to 630V and rated to operate over a wide temperature range of -55°C to +125°C.

Working Principle

The MKT1820647015 is a type of film capacitor, also known as a stacked-layer capacitor. It operates by creating an electrical field between the two parallel layers of metalized polypropylene film. The metalized layers create an electrostatic field by forming an “electric dipole” between the two layers. As an alternating voltage is applied, the capacitor stores the energy by transferring charge from one layer to the other.

As the voltage increases, the charge from one layer is transferred to the adjacent layer through the insulating dielectric material that separates the two layers. As the voltage decreases, the charge is gradually returned to its original layer. This back and forth movement of charge creates an electric field between the two layers and, consequently, a capacitive effect.

The capacitive effect allows the MKT1820647015 to balance the continuously changing current and voltage levels in the application. This provides a stable and reliable source of power to the application, which helps ensure that it operates at peak efficiency and reliability throughout its lifetime.

Conclusion

The MKT1820647015 is a high-temperature, low-profile film capacitor that is designed to provide reliable and stable performance in a wide range of applications. Its stacked-layer design allows it to store energy in the form of an electric field between the two layers. This allows the capacitor to manage the varying voltage and current levels in the application, ensuring that it operates at peak efficiency and reliability for its lifetime.
