Capacitors are important components of electrical circuits in many electronic devices, including pacemakers, cell phones, and computers. In this chapter, we study their properties, and, over the next few chapters, we examine their function in combination with other circuit elements.
W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.
In the 40-65 °C range, experimental data show that the life of the capacitor is decreased by a factor of 2 for every 8 °C of temperature increase. Above 65 °C, new failure modes have emerged, and the capacitor cycle life begins to degrade quickly.
Capacitance is a measure of the ability of a capacitor to store electrical charge. It is expressed in units of farads (F). The capacitance of a capacitor is determined by the size of its plates and the type of material used for the dielectric.
Understanding their function, the types available, and applications is essential for creating efficient electrical and electronic systems. Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material called a dielectric.
There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
Ceramics presently appear to be one intrinsically high-temperature, and hence long-lived, technology available that has a significant potential for advancement, particularly with the recent advent of new materials and the multilayer ceramic (MLC) capacitor demonstrated production capacitance and voltage scalability (»100/xF; >500 Vdc) [11,27,28].
