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.
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.
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.
ROBERT E. NEWNHAM, JAYNE R. GINIEWICZ, in Comprehensive Composite Materials, 2000 The multilayer design used for ceramic capacitors is an effective configuration for concentrating electric fields. By interleaving metal electrodes and ceramic dielectrics, relatively modest voltages are capable of producing high electric fields.
For most capacitors, a physically conditioned dielectric strength or a breakdown voltage usually could be specified for each dielectric material and thickness. This is not possible with ceramic capacitors.
In recent years, multilayer ceramic capacitors have become increasingly smaller and their capacitance has increased while their fabrication processes have been improved; for instance, the dielectric layers have become thinner and the precision with which the layers are stacked has been enhanced.

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. Ceramic capacitors are divided into two application classes:
