I recently saw a question posted on LinkedIn about whether purely reactive components produce noise like resistors do. This, of course, would be Johnson Noise, also known as Thermal Noise. I do not recall any mention of such noise in reactive components (inductors and capacitors) in my studies, other than the that attributed to the resistances associated with these components. And there is not much written about this subject. The few times I have seen anything written about this, it is stated th ...
