A multilayer ceramic capacitor is a capacitor made up of multiple layers of ceramic material. We can use this capacitor for various applications, including telecommunications, audio, and video. It is also applicable in …
Capacitors consist of two or more conductive plates (also called internal electrodes) separated by a dielectric material. As clearly denoted by the term ''multilayer ceramic capacitor'' the dielectric material for MLCCs is a ceramic. The structure is shown in Figure
Two types of ceramic capacitors are widely used in modern electronics: multilayer ceramic (MLCC) and ceramic disc, as shown in Fig. 8.5A and B [6,8]. Ceramic capacitors typically have small capacitances between 1 nF and 1 μF and a low maximum rated voltage compared with electrolytic capacitors and are nonpolarized.
