Introduction to Ceramic Capacitors
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.

8.2: Capacitance and Capacitors
Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1, negative charge will ...
