Film capacitors, or specifically the MKP1848C61090KK2 capacitor, are used in a variety of different electronic applications. The particular version of film capacitor has a build that includes a tube or shed-like casing made of polypropylene, and is particularly suitable for use in AC conditions and in situations where there is a greater than normal stress on the capacitor. With its protective casing, the MKP1848C61090KK2 is a particularly rugged choice of film capacitor, and is used with such confidence in various audio, industrial, medical, lighting, heating, ventilation, air conditioning, and other related applications.

The MKP1848C61090KK2 is also known as a metallized polypropylene film capacitor. This is because it contains metallized films which are of a laminated construction, which makes them the ideal choice for many AC and pulse applications. Generally speaking the metallized films are polyethylene terephthalate (PET) or polypropylene, and the MKP1848C61090KK2 is created with the latter. It has a polypropylene dielectric between two metallized electrodes and is typically considered to be one of the best capacitors for AC applications due to its high insulation resistance and low losses.

MKP1848C61090KK2 capacitors are tuned by winding the conductive surface with a thin layer of dielectric accurately balanced to provide perfect dielectric symmetry and therefore excellent symmetry of the electro-magnetic field between the two electrodes. This ensures an improved capacitanceperformance. When tuned for embedded applications, these capacitors provide low ESR (equivalent series resistance) and ESR stability over a wide range of temperatures. Furthermore, they are characterized by a high maximum permissible voltage, high reliability and long-term stability.

The main working principle behind MKP1848C61090KK2 film capacitors is the electrostatic principle. Two metallic electrodes opposing each other and separated by a dielectric become charged when voltage is applied. This creates an internal electric field between the oppositely charged electrodes to store electrostatic energy (charge). The stored energy is proportional to the capacitance of the film capacitor, which is in turn the product of the area of overlap between the two layers of electrodes and the permittivity of the dielectric separating them. The capacitance is therefore determined by the dimensions of the two electrodes and the permittivity of the dielectric material.

In summary, the MKP1848C61090KK2 film capacitor, which belongs to the family of film capacitors, is a rugged choice for a range of AC and pulse application. It is characterized by low ESR (equivalent series resistance) and ESR stability over a wide range of temperatures, with a high maximum permissible voltage and long-term stability. Its working principle is based on the electrostatic principle, whereby two metallic electrodes with a dielectric in between, store electrostatic energy when voltage is applied.
