Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Capacitors are tiny components found in almost every electronic device, but most people have no idea what they do. This video ...

If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...

Bypass capacitors are found in every working piece of electronic equipment. Most engineers know that systems, circuits, and individual chips need to be bypassed. The methods for choosing bypass ...

Capacitors may seem simple enough, but specifying them has grown more complex in recent years. The reason why comes down to freedom of choice. The universe of capacitors for embedded systems ...

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 ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
