We use a semi-intelligent internal PN system. To date, our resistors
are usually 5% or 1%. For 5%, we use 2 sig digits plus a multiplier
digit for the value, plus a letter code to indicate size. For 1%, we
use 3 sig digits plus a multiplier plus the letter code.
We now have a requirement to make some 0.1% resistor part numbers. We
are struggling with how to define it in our system. The thought was to
do 4 digits plus a multiplier, but to add to the confusion, the parts
are 1K and 2K21. This would mean the PN would have a number like 10000
for 1K and 22100 for 2K21.
Does anyone have any other ideas?
