Introduction Film capacitors, also known as polymeric capacitors, are an important type of capacitor made from a thin plastic film dielectric and a metal or conductive polymer top electrode (positive electrode) and a conductive polymer bottom electrode (negative electrode). Film capacitors are used in many different types of applications, including some of the most critical non-volatile memory, data backup and power management circuitry. The MKT1817347256D is a high-performance film capacitor that provides a reliable, durable and low capacitance solution for applications with limited space.FeaturesThe MKT1817347256D is a small-outline, thin-film design that suits applications that require high capacitance at very low profiles. This capacitor is designed to meet many of the most demanding requirements for high-performance capacitors in terms of long lifetimes, chemical resistance and high reliability. It is UL approved, RoHS compliant and can typically operate over a wide temperature range of -55°C to 125°C or even higher.Typical ApplicationsThe MKT1817347256D is suitable for all types of film capacitor applications where space is of a premium. These could include a variety of different applications such as solid-state memory devices, power supplies, LED drivers and LCDs, and many other consumer electronics.Working PrincipleThe working principle of the film capacitor is quite simple; as a charge is applied to the metal insulation material, the electrons migrate to the top electrode, creating a positive charge there. The positive charge then attracts electrons from the bottom electrode into the film, creating a negative charge there. This creates an electric field between the two electrodes, which acts as a field to store the electrical charge, or capacitance. This process is reversed when the voltage is reversed. AdvantagesFilm capacitors have a number of key advantages over other types of capacitors, including their small size, high reliability and long life, chemical resistance and ability to operate over a wide temperature range. They are also favoured over alternative components such as conventional ceramic or tantalum capacitors for their high energy storage capacity, low equivalent series resistance (ESR) and non-piezoelectricity.ConclusionThe MKT1817347256D is an ideal choice of film capacitor for applications with limited space and where reliable and durable performance are required. This component offers a superior set of features over other types of film capacitors, offering beneficial characteristics such as high capacitance values, chemical resistance and wide operating temperature range. In summary, the MKT1817347256D is an excellent choice for a range of low-profile film capacitor applications and is a key component in ensuring tight, robust control of an application\'s power supply or voltage output.
