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

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: ...

MEMS (Micro-Electro-Mechanical Systems) microphone technology is here to stay, so it is crucial to understand that technology. When it comes to choosing an analog or digital MEMS microphone, the ...

Also known as a trimmer capacitor, these are designed for fine adjustments or calibration in RF Circuits providing the ability to vary capacitance, allowing precise tuning and optimisation of ...

In order for the solenoid point motor to throw the point we need to apply current briefly to an electromagnetic coil. A capacitor discharge unit greatly improves reliability in that it builds up and ...

Advanced Energy Industries has been granted a patent for a variable capacitor bank design. The invention includes a conductive housing, electrical bus, and capacitor modules with switched capacitor ...

Article 460 of the NEC provides the requirements for installing capacitors on electrical circuits [460.1]. It does not address surge capacitors or capacitors included ...
