The MKP383147063JC02W0 is a series of film capacitors manufactured by the Knuerr Group and represented by two series: the MKP 37 Series and MKP 38 Series. The MKP383147063JC02W0 is a small size, board-mounted and threaded screw terminal, metalized polypropylene DC-link film capacitor for applications in power electronics. This type of metalized film capacitor can handle high surge current when compared to conventional film capacitors and is long-lasting. They are designed for a high discharge capability and are suitable for inverters, motor drives, and other energy consumption applications. The MKP383147063JC02W0 series has a maximum working voltage of 2500 Volts DC, a rated capacitance of 470,000 pF, and a high temperature of 125°C with an AC ripple current of up to 130mA RMS.

Film Capacitors are an essential component of many power-electronic circuits, as they provide reliable electric power storage and filtering capabilities. Compared to traditional electrolytic capacitors, these capacitors are not only more reliable, but also offer significantly higher capacitance ratings. It is generally easier to implement advanced voltage regulation, filtering, and other power management using film capacitors, as compared to more traditional capacitor types. Film capacitors are highly valued for their wide operating temperature range, high reliability and excellent performance in sustained high ripple current applications.

The MKP383147063JC02W0 consists of etching technology that is highly efficient and enables these capacitors to handle high power levels, including high current surges, with minimal additional circuitry. This capacitor is also hermetically sealed, making it suitable for vacuum and other special conditions. The metalized film capacitor is a type of electrochemical capacitor usually made from a thin-film dielectric material such as polypropylene, polystyrene, teflon, or glass. The film capacitor is then sandwiched between two metal sheets which act as the electrodes.

The working principle of the MKP383147063JC02W0 is based on the capacitive property of the metalized film. The two metal layers are separated by a thin-film dielectric, which stores the electric charge. When a voltage is applied on the capacitor, electric field is created that causes electric charges to be stored on the electrodes in capacitive fashion. The capacitance is then determined by the thickness and area of the dielectric, as well as the permittivity of the material. This type of capacitor is well-suited for filtering out AC ripple, mitigating EMI/RFI interference, and providing voltage regulation and noise suppression in high-power applications like inverters and motor drives.
