An assortment of capacitor types. From left: multilayer ceramic, ceramic disc, multilayer polyester film, tubular ceramic, polystyrene, metalized polyester film, aluminum electrolytic. Major scale divisions are in centimetres. Most capacitors have a dielectric spacer, which increases their capacitance compared to air or a vacuum.
These are primarily aluminum electrolytic capacitors, and tantalum as well as some film capacitors and Class 2 ceramic capacitors. Aluminum electrolytic capacitors, the most common type for power supplies, experience shorter life expectancy at higher ripple currents.
Capacitors are manufactured in many styles, forms, dimensions, and from a large variety of materials. They all contain at least two electrical conductors, called plates, separated by an insulating layer (dielectric). Capacitors are widely used as parts of electrical circuits in many common electrical devices.
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.
An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors.
In multi-layer ceramic capacitor, the conductive plates are metal electrodes such as silver or palladium, and the dielectric material is ceramic. When a voltage is applied to the electrodes, an electric field forms in the dielectric material, which polarizes the electrons, creating an electrical charge on the electrode’s surface.
