I need to make a high precision low reactance variable resistor divider and normal potentiometers do not have ultra low tolerance between channels so I am looking at stepped attenuators instead.
Only one seller seems to be making a PCB stepped attenuators which is something I'd like to use in order to reduce lead length.
DACT audio attenuators
The curious thing I found is that the quoted distortion is 0.0001% which should be about -120db. That seems rather high for a resistor. Anyone know what that's about?

Low enuff to be who cares?

Carbon film can be even higher in distortion. Thermal and/or voltage distortion
does happen in resistors.
You are caring about something that does not matter. It is too low and THD says very little about how something sounds.

+1
+ 1Probably not something they can measure, but as a manufacturer they have to spec something so they just picked a number....
The spec is juste there for a professional look.
