A capacitor consists of two metal plates and an insulating material known as a dielectric. Depending on the type of dielectric material and the construction, various types of capacitors are available in the market. Note: Capacitors differ in size and characteristics.
Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors.
Ceramic capacitors, especially the multilayer style (MLCC), are the most manufactured and used capacitors in electronics. MLCC is made up of alternating layers of the metal electrode and ceramic as the dielectric. And due to this type of construction, the resulting capacitor consists of many small capacitors connected in a parallel connection.
Standard, bi-polar, and polymer types are included. Figure 5: An illustration of the range of voltage/capacitance ratings for aluminum capacitors available through DigiKey at the time of writing. The primary strength of aluminum capacitors is their ability to provide a large capacitance value in a small package, and do so for a relatively low cost.
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. Capacitors, together with resistors and inductors, belong to the group of passive components in electronic equipment.
Capacitors are available in a variety of physical mounting configurations, including axial, radial, and surface mount (Figure 2). Figure 2: Capacitor mounting, or configuration types include axial, radial, and surface mount. Surface mount is very widely used at this time. (Image source: DigiKey)
