Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.
Introduction: Filter capacitor play a vital role in electronic circuits, contributing to their stability, reliability, and performance. These components are widely used in various applications, including power supplies, audio systems, and communication devices.

Electronic devices comprise a wide variety of electronic components. Capacitors, along with resistors and inductors (coils), are regarded as the three major passive components. Today, about one trillion capacitors are produced worldwide each year, 80% of which are multilayer ceramic chip capacitors, and 90% of which are made by Japanese manufacturers.
Photo: A small capacitor in a transistor radio circuit. A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store electrical energy and release it very slowly through a circuit; sometimes (in the case of a quartz watch) it can take several years. A capacitor generally releases its energy much more ...
In electrical circuits, the capacitor acts as the water tank and stores energy. It can release this to smooth out interruptions to the supply. If we turned a simple circuit on an off very fast without a capacitor, then the light …
