Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...
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 ...
I have too much noise on the 3.3V inputs to my ASIC. An FFT analysis of the noise indicates that it peaks at 125 and 300 MHz. The noise is coincident with the edges of the 25-MHz clock that the ASIC ...
