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.
C 2.9.1 Construction The capacitors consist, as the name tells us, of some kind of ceramic. The manufacturing process starts with a finely grounded ceramic powder mixed to an emulsion of solvents and resin binders.
The topic dealt with in this part describes the structure of multilayer ceramic capacitors and the processes involved in the production of these capacitors. The most basic structure used by capacitors to store electrical charge consists of a pair of electrodes separated by a dielectric, as is shown in Fig. 1 below.
The most common design of a ceramic capacitor is the multi layer construction where the capacitor elements are stacked as shown in Figure C2-70, so called MLCC (Multi Layer Ceramic Capacitor). The number of layers has to be limited for reasons of the manufacturing technique. The upper limit amounts at present to over 1000.
As technology progresses, the thickness of the layer decreases and capacitance increases in the same volume. Ceramic capacitor dielectrics vary from one manufacturer to another, but common compounds include titanium dioxide, Strontium Titanate, and Barium Titanate.
The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. An American company in the midst of the Apollo program, launched in 1961, pioneered the stacking of multiple discs to create a monolithic block.
