Film capacitors are composed of an insulating film as the dielectric and metal foil as the opposite electrodes. The polyester type capacitor (MKP385211125JC02W0) is commonly called a metalized polyester capacitor or "metallized" capacitor. It consists of a polyester film that is coated on both sides with a metal layer. This type of capacitor is characterized by its small size, light weight, low cost, large volumetric capacity and good ability to work in a wide temperature range.

The primary application field of MKP385211125JC02W0 is in filtering, bypassing, and decoupling applications. MKP385211125JC02W0 capacitors are also widely used in consumer and general electronic equipment. For example, they can be used in the circuitry of computers, radio receivers, televisions, damping devices, audio amplifiers, active filters, and for power factor correction. In addition, they can be used as coupling capacitors in oscillators and tuned circuits, and as bypass capacitors in power supplies.

Working Principle of MKP385211125JC02W0

The working principle of MKP385211125JC02W0 is based on the behavior of electrical charge. On the microscopic level, electric charges are generated by the asymmetric movement of electrons and ions and the displacement of electrons causes an electric field between the two sides of the capacitor. When a voltage is applied, charges move from one plate of the capacitor to the other, creating an electric polarization.

This electric polarization creates an electrical field within the capacitor, and the field will induce electrical charge to the opposite side. The charges produced by this electrical field are the basis of the electric charge stored in a capacitor. This stored electric charge creates a voltage across the capacitor that, in turn, causes a current to flow in the circuit.

The total capacitance of the device is determined by the factors like the size and shape of the capacitor, the dielectric material, and the distance between the two plates. Generally, the greater the surface area, electric field, and dielectric constant of the capacitor, the higher the total capacitance. The greater the capacitance, the more charge can be stored.

In conclusion, the MKP385211125JC02W0 is a type of film capacitor and has a wide range of applications in various consumer and general electronics. Due to its small size and low cost, it is one of the most popular types of capacitors used in the electronics industry. It has excellent temperature characteristics, and the capacitance varies depending on the type of dielectric material used in the film. The functioning of the capacitor depends on the electric field between the two plates, which in turn induces charge and produces the current flow in the circuit.
