Film capacitors are electrical components that store and discharge electrical energy. The MKT 1813368405 is a medium power self-healing polypropylene film capacitor. It is a component of film-paper-film type, designed and manufactured to use with high preciseness of less than 1%.

The application fields of MKT 1813368405 include, but are not limited to, general industrial access control, circuit protection, LED circuits, elevator, static switching power supply, PSC, HPF, amplifiers, broadband networks, medical equipment and power conversion circuits. The capacitors of this type can be used with kHz/MHz frequencies, alternating current, pulse circuits, etc. It can be used under the temperature range of -40°C to +105°C.

The working principles of MKT 1813368405 are based on the permittivity of the dielectric media between its two electrodes. The permittivity allows electric field to be created between the electrodes when voltage is applied to impose a charge on the electrodes. When the voltage applied is removed, the electric field is also removed, and the stored energy is discharged. The permittivity also influences how much energy the capacitor can store for a given voltage. As the voltage applied increases, the energy stored in a MKT 1813368405 also increases.

The construction of MKT 1813368405 includes two polypropylene film layers of same thickness, which are metallized with aluminum. The two layers are separated by another layer of aluminum oxide film. The electrical connection to the capacitor is made through two leads, which are attached to the two electrodes of layers of film. The capacitor is also provided with a cover to protect the two layers of film from external damage and moisture.

The advantages of MKT 1813368405 include high voltage rating, low impedance, high capacitance, good insulation property, and high pulse load strength. The components are also self-healing and provide protection from high voltages and short-circuits. Higher temperature spikes will not damage the capacitor and their life span can reach up to 40,000 hours. With all these features, MKT 1813368405 filament type capacitors are widely used in high-frequency power conversion and various electrical control systems.
