Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

http://www.bccomponents.comTo deliver on time and on budget, telecom designers need to make component selection decisions quickly. However, careful consideration must ...

What function does a capacitor auto-discharger perform in a power supply circuit, and how does it work? What are its fundamental building blocks, and can engineers develop a capacitor auto-discharge ...

An onion-like cluster of carbon sheets—think nested Russian dolls crossed with a buckyball—is the key to a new capacitor that can hold up to very high discharge rates.

A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conducting plates separated by an insulating material called a dielectric. When a ...
