As we have seen in part I and part II of this series [1], there are no inherent wear-out mechanisms in ceramic capacitors. And yes, as covered in part II, the high dielectric Class 2 capacitors (X7R) ...

Vehicle electrification is the biggest growth driver for capacitors used in power converters, according to a recent report from Yole Intelligence, part of Yole Group. The power capacitor market share ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...

Yi Liu (left) and Zongliang Xie fabricate film capacitors from polymers and then evaluate both the polymers and capacitors at the Molecular Foundry. The Department of Energy’s Lawrence Berkeley ...

Capacitors are energy storage devices, consisting of two electrodes and an electrolyte, that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the ...

Researchers have proposed combining two additives instead of one to facilitate the incorporation of lithium within capacitors, in order to promote the low-cost, simple, and efficient development of ...

When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
