A ceramic capacitor chip Ceramic chips for surface mounting looks in principle like the one in Figure C2-74. MLCCs are by far the leading downsizing and miniaturization technology among passive components. Chart bellow is illustrating shift of the case size mix in MLCCs.
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 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.
Safety capacitors are also called EMI / RFI suppression capacitors, AC line filter safety capacitors, or X- and Y-rated capacitors. X and Y capacitors not only keep radio frequency noise generated by the device local to that device, but also protect the device from mains noise and high voltage surges.
When we mount any ceramic capacitor to a PCB, there will be parasitic effects due to the PCB and pad dimensions that need to be considered in the electrical performance.
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.
Introduction to Ceramic Capacitors
Thin-film ceramic capacitors are using a single-layer low loss ceramic dielectric packaged as a multilayer ceramic capacitor (MLCC) – see figure below. Its advantage is in very tight capacitance tolerance (even low batch to batch variation) and a single resonant point response. Thus such design are ideal for RF and microwave filter designs.
