Film Capacitors

Film capacitors are widely used for various applications, including telecommunications, automotive, energy, consumer electronics, industrial applications, displays, and lighting. Film capacitors are mainly used for decoupling and filtering applications due to their low parasitic inductance, low dielectric absorption, high frequency response, excellent insulation properties, and stability of the dielectric layer. They also feature low ESR (equivalent series resistance) and have very low losses in comparison to traditional ceramic, electrolytic, or paper capacitors.

MKP1840268204M application field and working principle

MKP1840268204M is a metallized polypropylene film capacitor in an oval-shaped body and is a widely used capacitor. It is designed for a wide range of applications such as X-ray, welding, medical, high voltage energy storage, and general AC and DC circuit power supply equipment. The MKP1840268204M offers excellent performance characteristics, including high insulation resistance, high ripple capability, excellent frequency response, and low ESR and ESL.

This capacitor is constructed of a sheath and a metallized polypropylene film employing a polycarbonate resin as the dielectric material. Its structure consists of a polypropylene film sandwiched between two metalized layers and two electrode terminals. The dielectric layer is dispersed between the metallized layers to form a dielectric film. The metalized layers and the electrode terminals are connected together by spot welding on the resin bush.

MKP1840268204M offers high operating temperatures, up to 150°C, excellent voltage stabilization characteristics, and is ideal for applications requiring high-frequency operation such as audio equipment and radio frequency applications. When operated with high-frequency AC, it will not cause any audible distortion. This capacitor also has low impedance characteristics.

The MKP1840268204M operates on the electric field theory principle in Dielectric Film type capacitors. The capacitor functions by collecting electric charge through two dielectric layers made of different materials. These layers are connected and insulated by the polypropylene film making up the capacitor body. The electrodes, or terminals, allow a flow of electricity between the two layers. The amount of charge collected by the capacitor depends on the type of Dielectric Material, the area of the electrodes, and the electric field intensity between them.

The MKP1840268204M is resistant to moisture, corrosion, and extreme temperatures, and is relatively low cost, making it a popular choice for a variety of applications. It is also UL approved and RoHS compliant for those applications where safety is a requirement.
