A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
In 1920 Dubilier developed a capacitor consisting of a flaked sheet of mica coated on both sides with silver. He formed the Dubilier Condenser Company to manufacture them. Ceramic capacitors were also used in the 1920s due to a shortage of mica, but by the 1950s silver mica had become the capacitor of choice for small-value RF applications.
1.Mica Dielectric: The heart of the capacitor lies within the mica dielectric—a wafer-thin sheet of mica material. Mica assumes this role by virtue of its stability and insulating prowess. 2.Metallic Foil Electrodes: Positioned on either side of the mica dielectric are two metallic foil electrodes.
Silver mica capacitors are still indispensable in some custom applications. Circuit designers still turn to mica capacitors for high-power applications such as RF transmitters and electric instruments and amplifiers because cheaper ceramic and porcelain capacitors can't withstand heat as well.
In recent years, nickel has been the principal metal used for the internal electrodes of multilayer ceramic capacitors, and in the case of such capacitors, the dielectric sheets are coated with a nickel paste. After the dielectric sheets have been coated with the internal electrode paste, the sheets are stacked in layers, one on top of the other.
Mica capacitors bank on mica as the dielectric, while ceramic capacitors harness ceramic materials like barium titanate or ceramic compounds. 2.Stability Spectrum: Mica capacitors are celebrated for their prolonged stability, characterized by minimal capacitance fluctuations over time.

Mica has been used as a capacitor dielectric since the mid-19th century. William Dubilier invented a small mica capacitor in 1909 which was used in decoupling applications. They were put into large scale commercial production to meet military requirements in World War I. Mica is less prone to crack under mechanical shock than glass, a useful property for equipment subject to shellfire. Like glass, mica has a substantially higher permittivity than paper so capacitors can be made smaller…
