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 ...

MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has introduced the DLA 04051 series of vPolyTan™ polymer surface-mount chip capacitors, developed to meet the stringent demands of aerospace, ...

If you search through an electrical engineering textbook, you probably aren’t going to find the phrase “gimmick capacitor” but every old ham radio operator knows about them. They come in handy when ...

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

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...

(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 ...

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 ...

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, ...

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 ...
