What are the differences between the different polystyrene caps, please (loss tangent with construction type)?
radial vs axial ? (Inductance...?)
tined or not ?
brand & quality ? (for audio? old orange squared Siemens, exotic russian...)
It's about filtering an I/V resistor to ground for a DAC so no massive voltage & curent but I can listen to different results with a low value (1 nF) between two different styrene caps and I' m a little puzzled with that !
Maybe it is just the soldering operations ? different voltage tolerance ? Btw I even don't know if Polystyren cap is the best cap for that purpose (polypro or mica or MKC are better perhaps, teflon being not existing in those little size)?
Maybe the beginning of the winding (which is marked on axial caps often by a circle giving the voltage range and the external foil) ?
This cap is for filtering a Rhopoint resistor than some advised in a previous post.
thank you for your inputs to come

There is a manufacturer that is considered the better of current sources called LCR.
Soldering temp / melting temperature is definitely an issue.
Depends on the value you need.
If you are splurging on a nice rhopoint I would try these or the Relcap Polystyrene Film.
