wirewound resistors for passive i/v

lordearl · 14th May 2011, 03:54 AM

Seen a few posts around the place showing good feedback on the Econistor wirewound resistors when used as i/v stage - I believe these are the ones in questions:
http://www.farnell.com/datasheets/58277.pdf

But the other side of the coin is the theory behind it - film resistors (whilst a bit noisier) do not have frequency cut off points and high inductance.

Anyone have some experiences they can share?

Not having heard these makes a comparison difficult, but I can vouch for the custom made Texas Instruments Z foil, the TX2575 sound quality is excellent and far beyond the resistors I've used so far (anything from allen bradly, caddock, shinkoh etc).

For me the TX2575 is the most 'invisible' resistor.

you can be sure
the sound is better
test and see clearly
inductance is very small
not going to have
effect in this frequency range
