Anyone who works with older electronic equipment will before long learn to spot Rifa capacitors, a distinctive yellow-translucent component often used in mains filters, that is notorious for failures.

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 ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...

(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, ...

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 ...

There is a general trend of making electronics smaller and with more functionality. This translates into: “Cram it in there,” so naturally designers look to find smaller and smaller parts. What was on ...

How the fast switching speeds and other characteristics of SiC devices create new challenges in DC-link capacitor design. Key ...

The choice of dielectric material significantly influences the performance of film capacitors in high-frequency applications, impacting energy storage density, dielectric strength, and overall ...

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, ...
