Some surface-mount capacitors exhibit acoustic noise when operated at frequencies in the audio range. A recent design uses 10-μF, 35V X5R 1206 ceramic capacitors that produce noticeable acoustic noise ...

The MEXY metallized polyester Class X2 and Class Y2/X2 film capacitors suit across-the-line and line-to-ground interference-suppression applications. Available in values from 0.001 to 2.2 µF, the ...

Here’s an interesting idea: replace a disposable coin cell battery with a capacitor in order to filter the noise from an external power supply. [David Cook] is taking advantage of the falling costs of ...

Broadcasters encounter interference in two forms: that which someone may accuse the broadcaster of causing, and that which the broadcaster experiences. The most familiar type of the former is a ...

If you build electronic circuits on a regular basis the chances are you will have used capacitors many times. They are a standard component along with the resistor whose values are lifted off the ...
