Film capacitors, also known as plastic film capacitors, are passive components made of plastic films and are usually formed into a cylindrical or ellipsoidal body. They are constructed by winding a thin plastic film around cylindrical former or mold. These capacitors are mainly used to store electrical energy, filter high frequency signals, and create phase shift in circuits. The MKT1817268404G film capacitor is one example. It has a specific application field and working principle.

The MKT1817268404G film capacitor is primarily used for voltage-dependent applications, such as DC-DC conversion, power smoothing, ripple-filtering, and line frequency processing. It is designed with high-voltage requirements, which exceed the ratings of other regular capacitors. The MKT1817268404G is made of metalized polyester film, oil-impregnated paper, phosphor bronze electrodes and flat-wrap terminals. This combination of materials provides it with high dielectric strength, excellent insulation and high temperature stability, ensuring reliable performance and a long life.

The working principle of the MKT1817268404G is based on the physical properties of capacitor, namely that the capacitance is proportional to area A and inversely proportional to distance d between two conductors. This means that when a voltage is applied to two metal-covered plates,electric flux is generated and stored in the space in between these two plates. The greater the voltage applied to the two plates, the larger the electric flux and the greater the capacitance. The MKT1817268404G has a series of metallized electrodes on both sides of its film, and the distance between each pair of electrodes affects its capacitance value, allowing the capacitor to store different levels of electric flux.

The MKT1817268404G is one of the most popular film capacitors in the market, due to its high voltage requirements, high dielectric strength, excellent insulation and temperature stability. It is suitable for a wide range of applications, including DC-DC conversion, power smoothing, ripple-filtering, and line frequency processing. Its ability to store different levels of electric flux also makes it an ideal solution for voltage-dependent applications.
