Film capacitors, also known as plastic film capacitors and polyester capacitors, originally used in the mid-20th century, are now widely used in various electronic circuits. As its core, it is composed of a thin plastic film layer that is coated with metal electrodes and then rolled up into a cylinder or folded into a flat shape. Their general descriptions include voltage ratings, capacitance range, low noise characteristics, operating temperatures and current derating.

MKP1848C65050JP5, a series of film capacitors made by the Taiwan MKC capacitor factory, is a polyester film capacitor composed of metallized polyethylene terephthalate (PET) films. It has a voltage rating of 650V DC, a capacitance range of 0.015µF~0.22µF, a noise characteristics of 16~180V, an operating temperature of -25~85°C, and a current derating of 10% for frequency above 25 KHz.

The application field of MKP1848C65050JP5 is mainly in the field of power electronics, such as power supplies, communication equipment, computers, automatic control and measuring systems. This product is suitable for the filtering, energy storage, resonance and coupling of PFC systems, power rectifiers, microcomputer protection circuits, harmless circuit noise reduction and other, as well as other signal circuits where high frequency noise proof and high temperature resistance are needed.

In general, MKP1848C65050JP5 film capacitors have the working principle of storing energy in the electric field created by the separation of electric charge between two conductors, such as the metal plates. The metal electrodes are charged with electrical current which creates an electric field. This electric field produces an electric charge between the two metal plates, and compresses dielectric material, such as polyester, between them. When an alternating current is supplied, the electric charge fluctuates and a reverse current is generated, dissipating the energy stored in the dielectric in the form of heat.

In conclusion, MKP1848C65050JP5 film capacitors are widely used in various electronic circuits due to their low noise characteristics, operating temperatures, current derating, and capacitance range. Their application field mainly covers the fields of power electronics, such as power supplies, communication equipment, computers, automatic control and measuring systems. As far as their working principle is concerned, they store energy in the electric field created by the separation of electric charge between two conductors, such as the metal plates, and dissipate the energy stored in the dielectric when an alternating current is supplied.
