Film Capacitors

Film capacitors, also known as metallized film capacitors, polyester film capacitors, and plastic film capacitors, are a type of capacitor which utilizes a thin plastic film, such as polyester as its dielectric, metallized electrodes, and a plastic case. These capacitors are commonly used in circuits where space is limited, such as power supplies, motor drives, and signal processing. The MKT1818422066G is a film capacitor that is designed for use in many applications and offers excellent performance characteristics.

MKT1818422066G Application Field

The MKT1818422066G is an advanced film capacitor which is suitable for use in a wide variety of applications. It is primarily designed for use in high-frequency switching circuits and motor drive systems, but can also be used in more general purpose applications such as signal processing and power supply designs. The capacitor has excellent characteristics, such as high stability, low ESR, low self-inductance, and good temperature tolerance. It is also RoHS compliant, and is available with voltage ratings from 100V to 400V.

MKT1818422066G Working Principle

The MKT1818422066G is a film capacitor which operates on the principle of electrostatic charge storage. This capacitor utilizes a thin plastic film as its dielectric and two metallized electrodes. When a voltage is applied to the electrodes, an electric field is created and the plastic film becomes polarized, forming an electric double layer across the gap between the electrodes. This layer of charge stored in the capacitor is held in place by the displacement current in the wires and the dielectric of the plastic film. As the capacitor is charged, the displacement current increases as the dielectric is further polarized, and the electric field of charge within the capacitor increases. When the current in the wire stops, or when the power is removed from the circuit, the displacement current decreases and the electric field of charge is discharged, releasing the stored energy back into the circuit.The MKT1818422066G is also designed with high quality construction in mind and features high endurance and excellent environmental robustness. The metallized electrodes are robust and capable of enduring temperatures up to 105°C with no degradation of performance. The capacitor also features an extended rated temperature range of -40°C to +105°C. The plastic film also provides excellent moisture resistance and makes the capacitor suitable for use in areas with high levels of dampness or humidity.

Conclusion

The MKT1818422066G is an excellent film capacitor for use in a wide variety of applications. It features excellent performance characteristics such as low ESR, low self-inductance, and good temperature tolerance, as well as impressive environmental robustness. The capacitor is also RoHS compliant and is available with voltage ratings from 100V to 400V. With its versatility and reliability, the MKT1818422066G is an ideal choice for use in high-frequency switching circuits, motor drive systems, signal processing, and power supplies.
