Film Capacitors

The MKT1813422105 is a film capacitor, also known as an MKT capacitor. This type of capacitor is composed of two conductive surfaces, each of which is separated by an insulating film. It provides a higher capacity than ceramic capacitors and has a wide range of applications.

Applications

The MKT1813422105 is mainly used for power electronics, such as power supplies, dc-dc converters, switch mode power supplies, and inverters. It is also used for filtering, decoupling, radio frequency interference suppression, and is suitable for high voltage and temperature applications. MKT capacitors have low equivalent series resistance and very low inductance, making them ideal for noise suppression.

Working Principle

The working principle of the MKT1813422105 is relatively simple. It is composed of two conductive surfaces, each of which are separated by an insulating film. When a voltage is applied to the capacitor, electrons are attracted to one of the conductive surfaces, creating a charge that is proportional to the voltage applied. This charge results in an electric field within the dielectric material that opposes the applied field and causes a decrease in the voltage across the dielectric.

The MKT capacitor also has a dielectric voltage breakdown rating, much like a ceramic capacitor. This rating shows the maximum voltage the capacitor can safely withstand without failing due to excessive current.

Conclusion

The MKT1813422105 is a film capacitor, ideal for applications requiring high capacity, high stability, and excellent reliability. Its characteristics render it suitable for many applications, such as power supplies, dc-dc converters, switch mode power supplies, and inverters. The working principle of the capacitor is based on attracting electrons towards one of the conductive surfaces, creating a charge proportional to the voltage applied. If the capacitor is subjected to a voltage higher than its dielectric breakdown rating, the capacitor will fail due to excessive current.
