2. Working Principle of MKT1820322636

The MKT1820322636 is a kind of metallized polyester film capacitor made of metallized polyester film and plastic film. This polyester film has a thin layer of metal (aluminum) on its surface, which increases the heat resistance and dielectric strength of the material. The two materials are then wound together into a cylindrical shape and sealed in plastic housing. The electrical connection occurs via lead connection, which are embedded in the film and connected to the external terminals.

When an alternating voltage is applied to MKT1820322636, an electrostatic field is induced in the capacitor. The electrostatic field induces a current to flow in the capacitor which is of a capacitive nature. This current is then stored as the electric potential energy. As the power source is pulsating, a frequency-dependent current is created at the capacitor terminals. The capacitor’s capacitance and volt-time limit depends on the properties of the materials used for construction. The materials used in MKT1820322636 are carefully chosen which result in excellent performance.

The MKT1820322636 film capacitor also has a wide temperature range. This temperature range enables the capacitor to be used in ambient temperature between -40°C and +105°C. Furthermore, the voltage range is also wide that it can be up to 3KV. Moreover, its high capacitance ripple current is another advantage of the MKT1820322636.

3. Conclusion

To sum up, MKT1820322636 is a kind of film capacitor which has many application fields, such as highest quality audio equipment, switchgear, power supplies, high frequency filter applications, snubber and DC link circuits, etc. In addition, it has excellent characteristic values, such as wide voltage range, high capacitance ripple current, wide temperature range, etc. With these properties, MKT1820322636 is widely applied in many industries.
