Introduction
Film capacitors, also known as plastic film capacitors or paper film capacitors, are passive components whose task is to provide energy storage and act as filters in electronic circuits. They are investigated here, particularly in the case of the MKT1822415255 type, looking at their application fields and working principles.Capacitor types
Generally speaking, film capacitors have two metal plates etched onto the surface of a polypropylene film material, and then covered with a layer of varnish that maintains the electrical insulation of the intervening film. The whole is wound with several layers of paper and ultimately packaged in a cylindrical shape. They are, of course, non-polarized.Film type capacitor family
The MKT1822415255 type belongs to a subset, the polyester film series, also known as the family of metallized polyester film capacitors. This family features several materials like metallised polyester, polypropylene, and polyethylene terephthalate (PET).Application fields of the MKT1822415255 type
The MKT1822415255 capacitors are used for a variety of applications, including broadcasting and receiving systems, electronic filters, and AC circuits. Thanks to their excellent electrical properties, dielectric films, and metal layers, they are particularly well suited for AC arc prevention, frequency selection, and energy storage. They can be easily used to build circuits for low-frequency attenuation as well as linear circuits for signal modulation.The Working Principle of the MKT1822415255 Type
The MKT1822415255 capacitors rely mainly on electrical energy stored between two conductive plates. The electrical energy stored in the form of an electric field is generated by the presence of a dielectric film, a stationary electric charge, between those plates. The stored energy can then be released, or discharged, as an electric current when it is necessary. These capacitors are able to store and release a large amount of current, so their application in AC circuits for arc protection, as well as in filter circuits, is fairly common.Characteristics of the MKT1822415255 Capacitors
The MKT1822415255 type capacitors are built with a metallised /pet/polyester film that offers greater charge storage capacity, better temperature stability, higher breakdown voltage, and lower equivalent series resistance. Furthermore, they exhibit a smaller temperature coefficient and very good linearity.In addition, these capacitors can operate within temperature ranges from ‒40℃ to +120℃, and are able to handle up to 40 V AC or 60 V DC. The capacity of these capacitors ranges from 5pf to 100µF. Their overvoltage characteristics are also excellent, and they can withstand up to 5000V.Conclusion
Film capacitors are widely used in electronic circuits for their high dielectric strength, stability and excellent electrical properties. The MKT1822415255 type is a part of the polyester film family and is particularly well suited for energy storage, ARC protection, signal modulation and frequency selection. Generally speaking, these capacitors feature good temperature and voltage stability as well as small temperature coefficient, and they can handle up to 5000V. In conclusion, their applications are varied and they are one of the most reliable and diverse film capacitors available.
