I have eBought a bunch of THT resistors recently.
Tolerance: 1%, power: 1/4W, metal film, we ship from HK, welcome you.
Ok, so I am picking two random ones of same nominal value, connect in series, apply a 5xAA battery pack (~7.7V) and DCV measure both voltages of the divider with my dmm on a 4V range (40Mohm input impedance).
I inspected several batches from 1k-100k range, no touching etc.
For some pairs the ratio of above voltages is ~1.06
I did not measure the nominal values of those resistors yet, I just wanted to check tolerances (all have "Chinese Brown" tolerance stripe).
Concluding: onepercentmyass. The values are all over the shop, not even 2%.
