In the same way the Single Layer Ceramic Capacitor (SLCC or just SLC) consists of one dielectric layer. The ceramic is covered with an adhesive layer of, for example, chrome nickel as a base for copper electrodes. On the electrodes leads are soldered as shown in the principle Figure C2-69, before the component is encapsulated in lacquer or epoxy.
The schematic diagram of a ceramic capacitor can be broken down into four main parts: the positive terminal, the negative terminal, the dielectric material, and the metal plates. The positive and negative terminals represent the source and destination of an electrical current, respectively.
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.
In a single-layer design, a single ceramic layer serves as the dielectric between two plates, keeping the construction simple and cost-effective. These capacitors come in different forms including disc ceramic and plate ceramic capacitors. Disc ceramic capacitors have a simple, disc-shaped design.
The basic construction types include simple – single-layer SLCC ceramic capacitors and major types made by stacking technology – MLCC multilayer ceramic capacitors. Single layer ceramic capacitor SLCC Example of high density MLCC on board of smartphone around and under the main processor (removed)
Disc ceramic capacitors have a simple, disc-shaped design. They consist of a ceramic disc with electrodes on either side. These capacitors are commonly used in low-frequency applications and basic electronic circuits. A multilayer ceramic capacitor consists of multiple layers of ceramic material interleaved with metal electrodes.
