Working Principle of MKT1818315254D

The MKT1818315254D is a type of metallized polyester film capacitor. The working principle of this type of capacitor is based on the fact that when a voltage is applied to two metal plates separated by an insulator, a current will flow. The current is proportional to the amount of voltage applied and the capacitance of the capacitor. The capacitance can be adjusted by changing the thickness and the dielectric constant of the insulator. This is done by coating the metal plates with a dielectric material with a known dielectric constant. The resulting capacitance is determined by the thickness of the dielectric material and the dielectric constant.

The MKT1818315254D is an NPO capacitor that is made from a polyester film, which has a dielectric constant of 3.9. This is higher than some other types of film capacitors and results in higher capacitance and lower equivalent series resistance (ESR).
