MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new series of high-voltage ceramic disc capacitors designed to improve efficiency and reliability in demanding industrial and ...

Dielectric capacitors store energy through polarization rather than chemical reactions, enabling rapid charging, high power density and long cycling life. Polymer films are especially attractive ...

You can work with a part for many decades, and still learn something new about it. At least we can, and we don’t mind admitting it. Take film capacitors — we all know they aren’t a polarized part like ...

Once upon a time I was a real mad scientist. I was into non-conventional propulsion with the idea of somehow interacting with the quantum vacuum fluctuations, the zero point energy field. I was into ...

Characteristics of conductive polymer aluminum solid capacitors include very low ESR and very high ripple current. Man Yue ...

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the ...

Defective capacitors--or "bad caps" as they are sometimes called--can disable your computer. And while they may not be widely familiar to consumers, they're nothing new to the PC industry. Capacitors, ...

When Ceramic Capacitors Go Bad – Aging. Capacitor Aging applies to all Class 2 ceramic capacitors as they are built of ferroelectric materials. C0G types (Class 1) do not exhibit this aging effect, ...

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 ...
