Sequential Bins With Different Nominal Values
Suppose that the batch of nominally 100 Ω resistors is to be sorted according to actual value instead
of according to tolerance, as in the previous example. Then the bins can be set up to have different
nominal values, with each bin width expressed as a percentage of the nominal value:
Bin 0: 98 Ω ± 1%
Bin 1: 100 Ω ± 1%
Bin 2: 102 Ω ± 1%
Bin 3: 104 Ω ± 1%
Bin 4: 106 Ω ± 1%
Bin 8: QDR failure (if Q is too high)
Bin 9: General failure bin (parts not falling into any other bin)
Figure 4-2 illustrates this example of sequential bins with different nominal values.
