Film capacitors, also known as plastic film capacitors, use a film dielectric material instead of a liquid or paper dielectric material. The film capacitors include MKP383382025JF02I0 type, which has many excellent characteristics and wide application fields. Its working principle is related to the type of film capacitor.

MKP383382025JF02I0 type film capacitor is mainly made of plastic film as the dielectric material, metal foil as the electrode, and the case made of plastic, metal or other material as the package. The metal foil is dipped in the lacquer-like electrode material before winding, and the upper and lower edges of the film are connected to the end cover by the soldering process, and the cut surface of the aluminum foil is plated with solder. MKP383382025JF02I0 type film capacitors have the advantages of small size, light weight, low equivalent series inductance and good frequency characteristics. Generally, its equivalent series resistance (ESR) value is small, insulation resistance is relatively large, and dielectric absorption and leakage current are low. Therefore, it has the characteristics of high frequency response. Moreover, it has good linearity of capacitance and series inductance versus temperature, as well as self-healing.

The working principle of the MKP383382025JF02I0 type film capacitor is that charge is stored on the dielectric surface of the capacitor. The dielectric has no effect on the current, so the dielectric only affects the capacitance of the capacitor, that is, the amount of charge stored by the capacitor. When a capacitor is connected to an alternating current (AC) circuit, the charges and discharges produce a current to provide the source of energy for the circuit. In practice, the current created by the capacitor is inversely proportional to its frequency, meaning that the capacitor will reduce the amplitude of signals with higher frequencies.

The MKP383382025JF02I0 type film capacitor is mainly used in AC and radio frequency filter circuits of television and radio receivers. In addition, the film capacitor is also widely used in other fields such as electron tubes, feedback circuits, coupling circuits, negative feedback amplifiers, audio frequency crossovers, overflow protection for power supplies, tuning circuits, and electromagnetic shielding. Due to its excellent frequency characteristics, soft tune microwave oscillator frequency can also be stabilized with MKP383382025JF02I0 type film capacitor.

In conclusion, the MKP383382025JF02I0 type film capacitor, as a kind of film capacitor, has the advantage in high frequency response, low equivalent series inductance,linearity of capacitance and series inductance versus temperature, and self-healing. In addition, it has a wide application range, such as electron tubes, feedback circuits, coupling circuits, overflow protection for power supplies and tuning circuits. Finally, due to its advantages, MKP383382025JF02I0 type film capacitor is widely used in AC and radio frequency filter circuits of television and radio receivers.
