Film capacitors are composed of a thin dielectric film between two conductive electrodes. The dielectric film used is generally a polyester film (such as mylar or polyethylene teraphalate (PET)), but plastic film, ceramic film, and other specialty films are also used in certain applications. Film capacitors have several advantages over other types of capacitors, including high-voltage operation, low dielectric absorption, better temperature stability, and low inductance. These characteristics make film capacitors well-suited for a variety of power electronic applications.

The MKT1813310405G is a polyester film capacitor manufactured by Kemet Corporation. It features a non-polar dielectric, high voltage rating (18KV), and low distributed capacitance and inductance. This makes it an ideal choice for high voltage DC filter applications, as well as AC line filtering and power supply bypass applications. It is also often used in automotive and industrial power electronics, medical imaging, and audio/visual equipment.

The working principle of a film capacitor is based on the capacitance created when two conducting surfaces are separated by an insulating medium or dielectric. When a voltage is applied, the current in the capacitor is limited by the amount of dielectric constant of the material separating the two conductors, resulting in an across-the-device electric field. The higher the dielectric constant, the more capacitance is created with the same physical size of the capacitor. The MKT1813310405G capacitor features a non-polar dielectric material and thus has a higher breakdown voltage and a lower distributed capacitance and inductance than other types of capacitors.

In addition to its applications in power electronics, the MKT1813310405G capacitor is also well-suited for use in vibration damping, RF and signal filtering, and instrumentation. In vibration damping applications, it helps to reduce noise and vibration of mechanical systems by providing a improved isolation and filtering of vibrations. In RF and signal filtering applications, it helps to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) from entering the components, thus improving the overall performance of the system.

The MKT1813310405G capacitor is well-suited for a variety of power electronic applications due to its high voltage rating, low distributed capacitance and inductance, and its non-polar dielectric material. It is also suitable for vibration damping, RF and signal filtering, as well as instrumentation applications. Its capabilities make it an ideal choice for high voltage DC filter and AC line filtering applications.
