The RH series of Vishay is not non-inductive, and that is what my op said they don't have. They still don't.
thanks
Caucasian Blackplate stated that Mouser has everything but the non-inductive spec. You want a non-inductive resistor when the signal is present so that you don't bleed off vey high frequencies. Most of the time, however, the concern is bleeding Mega or Giga Hz signal.
For a cathode resistor you are following the advice that "someone said that inductive resistors are bad so obviously they are bad everywhere". An un-bypassed cathode resistor creates feedback. Therefore if the resistor was inductive and affected the audio frequency band the frequency of this feedback would not be flat and you would hear high frequency roll-off. The fly in that ointment is that a bypass cap eliminates the feedback so there is no effect, even in the Mhz where it will show up. If you are running an in-bypassed resistor on your output, well, lets just say the inductance is the least of your problems.
No, caucasian black plate said that mouser had the resistors I had posted about originally, and I was pointing out that they did not because I had been looking for non-inductive resitors and mousers were not. Whether they need to be or not was an entirely different matter.
You apparently did not read the whole thread as I also stated in a later post that it appeared from info I had found on the web and other posts made that I might not need non-inductive resistors.
This whole thing was a very good example of how things can really get mixed up in some of these threads.

Of course I do. I am just pointing out that it is too easy to get going down the wrong path sometimes. That is what happened and I thought it best to say something so other folks did not get the wrong information.
