Film capacitors are widely used in the electric industry to reduce electric noise, provide buffering, or store charge among other uses. One type of film capacitor known as the MKP1839368404 has been specifically designed for automotive applications. This particular capacitor features a high surge capability, high polarity switching capabilities, high thermal stability, and very high leakage current. In this article, we will explore the application field and working principle of the MKP1839368404.

Application Field of the MKP1839368404

The MKP1839368404 is designed to be used in automotive applications where high surge, polarity switching, thermal stability, and leakage current are all important. It is especially ideal for applications with higher temperatures, such as engine control units, engine starters, and powertrain components.

The MKP1839368404 is also used in applications where the device must withstand vibration. This makes it ideal for automotive suspension systems as well as other vehicle-mounted components. The capacitor is also suited for applications involving signal isolation, reverse polarity protection, and motor speed and direction control.

Working Principle of the MKP1839368404

The MKP1839368404 is a part of a larger series of film capacitors known as polypropylene film capacitors. These capacitors are constructed using two metal electrodes separated by a thin film made of polypropylene. The polypropylene dielectric layer provides excellent dielectric performance and a high level of insulation. The two electrodes provide the necessary electrical connection points to the electrical circuit.

When an electric current passes through the two electrodes, a corresponding charge is stored within the capacitor. This charge is then released when the capacitor is discharged, which occurs when the voltage drops below a certain threshold.

The MKP1839368404 also utilizes two additional layers of metalized material to increase thermal conductivity and reduce the effects of temperature cycling on the device. This makes the capacitor more resistant to temperature variances and extends its useful lifespan.

Finally, the MKP1839368404 also features a large surge capability, which ensures that the capacitor is able to withstand high on-off cycles. This helps to protect the capacitor from potential damage caused by sudden voltage changes.

Conclusion

The MKP1839368404 is a specialized film capacitor specifically designed for high-temperature automotive applications. It is designed to provide high surge capability, high polarity switching, high thermal stability, and high leakage current. The capacitor is also designed to withstand vibration and sudden voltage changes, making it ideal for automotive suspension systems and other vehicle-mounted components. In addition, the additional metalized layers increase thermal conductivity and provide better temperature cycling protection.
