There’s one component which used to be ubiquitous in every experimenter’s junk box, but nowadays unless you happen to be a radio amateur the chances are you may not have seen one in a long time, if ...

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: you can ...

Electronically-variable capacitors, whether used for T&M or in an end circuit, usually have a maximum capacitance of a few hundred picofarads, and a limited adjustment range. This Design Idea ...

This application note discusses bypass capacitor and introduces its properties and applications. Bypass capacitors are applied between the power supply pins VCC and GND of integrated circuits. They ...

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 ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...

This file type includes high resolution graphics and schematics. Cavendish Kinetics now offers a tunable RF micro-electromechanical systems (MEMS) capacitor that lets smart-phone antennas cover a ...
