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: ...

The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance (ESR). ESR determines the capacitor's I 2 R heating ...

Their small size in a wide range of values suits them for applications where space is at a premium, such as mobile phones, digital audiovisual equipment, and PCs. The tiny capacitors, which suit flow ...

Some 99 percent of the “design” problems associated with linear and switching regulators can be traced directly to the improper use of capacitors: wrong type, wrong value, or incorrect physical ...
