Quickly sorting resistors
How to sort a batch of resistors?
I received a batch of about 200 resistors from the E24 serie (3 bands) that I want to sort. Here is a solution for a quick sort:
- Make a first sort according to the multiplier coefficient
This is usually the 3rd band, but maybe the 4th or 5th for the E48 or E96 series.
- For this value, we find the following colors:
- black = × 10⁰ = × 1
- brown = × 10¹ = × 10
- red = × 10² = × 100
- orange = × 10³ = × 1000 (× 1k)
- yellow = × 10⁴ = × 10,000 (× 10k)
- green = × 10⁵ = × 100,000 (× 100k)
- blue = × 10⁶ = × 1,000,000 (× 1M)
- purple = × 10⁷ = × 10,000,000 (× 10M)
- gray = × 10⁸ = × 100,000,000 (× 100M)
- white = × 10⁹ = × 1,000,000,000 (× 1G)
- Make a second sort according to the first band
- black = 0
- brown = 1
- red = 2
- orange = 3
- yellow = 4
- green = 5
- blue = 6
- purple = 7
- gray = 8
- white = 9
- Make the last sort according to the second band.
To store the resistors, I use small plastic bags that I group into larger bags: 1 to 90 ohms, 100 to 999 ohms, etc. The bags are then stored in plastic jars with a wide opening. Three jars are enough to store several thousand resistors...
