No. Precision wirewound resistors are going to be using specific alloys (Manganin, Constantan etc) and minimal stress windings. The only real purpose of one of those bog standard wirewounds is to dissipate heat, so no real care in construction.
Yes, wirewound resistors can still drift. Changes in composition (you specifically don't want to dissipate heat in a precision resistor), Winding stresses (if the wire gets too tight on the former it will stretch and get thinner!) etc. NOTHING stays constant forever, but with close attention to construction in precision parts, you can minimise it. The mouser resistors aren't precision in the 'laboratory resistance standard' sense, they are just 'good'. The Tayda are neither in this context.
Cement resistors transition from wirewound to film at some arbitrary value, depending on size (the wire gets too thin and hard to wind at some (price)) point.
Thanks, constantly learning in this hobby; having fun I think what I am going to do is take some Royal Ohm 1 cent metal film resistors (1%) , say like 3 of them, to my local electronics store and see if they'd kindly measure them for me on a calibrated scope Then perhaps go there every year with the same resistors to see how they drift and to update the values if changed. I need some local electronics buddies -- I'll have to look into that.. can share resources and ideas to save money, etc. _ I wonder if I should bring my probemaster leads if that makes a difference.. I imagine using the same leads on both unit and the calibrated unit would help?
excuses me 1% resistor as a reference is pure #$##^ you need at least 0.0xx percent precision resistors i have 0,0014% ones from an old calibrator, even theses will be affected by temperatures and or humidity
precision stuff like, meters have warm up times, precision references too, precision resistors etc ... you are venturing in a different world when you talk about precision references
an 6.5 digit meter cost me 160$ CAD, i had 3x oldies hp 34401A meters, and now i've switched to more modern stuff, it cost a little bit more ...
i have 300,000 count Gossen Metrawatt meters, same price here 160$ cad for each ...
I mean like others you need some references points before thinking doing some precisions stuff, grab an 5.5 digits or more meter and make it calibrated and keep it clean and stabilized in temperature and humidity
That's why people love old meters like the 34401a, when working perfectly they have "aged" very well and got pretty stable over the years, one i had was almost 25 years and was pretty close to "calibrations standards" even calibrated 10 years after the last calibration sticker
You could buy a precision reference divider network like the ones we find in meters, they can go up to 20-25$, they will be way better than the 1% precision idea
