Film capacitors are capacitor types which are mainly composed of a film dielectric and two or more electrodes. As one of the most commonly used capacitors in industry and daily life, they are widely used in the area of pulse generator used for consumer applications like electric shavers and toys.

Among different kinds of film capacitors, the MKP385413040JFI2B0 is one of the most frequently used. It has a capacitance of 0.33 microfarads and a temperature range from -40 to 85°C, which makes it suitable for both indoor and outdoor use. Moreover, its voltage rating is being up to 400VAC, and its typical dissipation factor is 0.17 at 1 kHz.

Coming with the features mentioned above, the MKP385413040JFI2B0 is most known for its advantageous performance in interrupting and filtering power applications. Because of its low stray inductance and low ESR, it is suitable to be used in safety equipment, lighting systems, and driver circuits. For instance, it is often applied as the input and output harmonic filter of servo motor drive, power amplifier and other machinery industries.

To explain its working principle, the MKP385413040JFI2B0 consists of two electrodes and a polypropylene film. When the capacitance is exposed to a high frequency input, the polypropylene film acts as a shield by allowing electric current rate to be reduced. By being supplemented with electric charge, it creates an electric atmosphere between the electrodes, influencing the speed and intensity of electric charges flowing. This produces an impedance which reduces electric current.

The MKP385413040JFI2B0 is also widely applied in the area of high voltage impulse capacitors, which feature an oscillating circuit of lowpass reactance with the capacitor. After the large current spikes flow through the capacitor, the device helps to reduce the output voltage fluctuation and produce a smooth pulse power.

As for self-healing properties, this device includes a detection circuit. When the dielectric fails due to overload or overvoltage, the electric current will be partly blocked, thus the capacitance will be slightly reduced. As soon as the overload or overvoltage problem fades, the dielectric film will start to heal itself. In this way, the damage of the capacitor will be minimized, ensuring better protection.

To conclude, the MKP385413040JFI2B0 is a film capacitor type that is mainly used in low-resistance applications. Its remarkable performance in terms of inductance, capacitance and ESR has made it a popular choice among engineers in both low and high voltage power supply systems, such as servo motors, power amplifiers and lighting systems. With additional features like impulse capability, high frequency switching, good self-healing effect and a wide temperature range, the MKP385413040JFI2B0 is well-suited for many practical applications.
