I was killing some time last night before going to my first maker space meeting, watching some Dave videos.
In the first video Dave finds that some Philips resistors have a ~
+/-0.5% distribution right around the ?correct? value.In the second he finds that some cheaper (Xicon?) also have a 0.5% ?spread?, but the average is a bit (~0.35%) lower than nominal.
This raises a bunch of interesting questions. Do any resistor makers publish this sort of data? Does buying resistors from a ?better? manufacturer lead to resistors with a better mean. I use mostly cheap Xicon 1%ers. A few times I?ve gone hunting through the parts bin with an ohmmeter trying to find some particular value. Though I don?t have any data I did strike me that the average seemed a bit low. (When looking for a 10.0k ohm I found many more 9.9X k ohms than 10.0X k ohms.)
So does anyone know how 1% resistors are made? I find it hard to believe that they trim each one. (Do they trim the 0.1% ers?)
