I'm guessing that the 4214 10K standard has a resistance curve
that peaks around 73F??? I've searched for old pix of data and can't find
any. The 4214 I got this week had no old, original data with it in its box.

Over the past few years there have been some resistance standards
sold on fleabay with pictures of temp vs. resistor value charts pasted
on the top cover. They may not have been 4214s, though. I also just
discovered that fleabay drops its pix on items sold past a certain date.

So, volt-nuts.... any help??? Alphas, Betas, charts?

Hi Willy,

For what it's worth I have attached the resistance vs. temperature curve for
my 10 k Rubicon which is of similar construction. It has a peak at about
23.5 degrees C.

Best regards,

mitch

Manufacturers specs:

Initial accurary +/-3ppm at 25C
Stability +/-3ppm first year
alpha +/-0.2ppm/C max, slope of curve at 25C
beta +/-0.05ppm/C max
Power coefficient +/-0.1ppm/W
Dielectric soakage <+/-0.1ppm of final value 10 seconds after 10V applied
Current reversal effect <0.1ppm
DC/AC(1592Hz) <5ppm

Rt=R25[1+alpha(t-T)+beta(t-T)^2], T=25C
