For each tolerance band, the EIA allocates E-series (E3, E6, E12, E24 and E96) to name the resistor values. The standard decade resistors (also known as preferred values) are shown in the below table. The resistance calculation is starting from 1 ohm with tolerance range (36%, 10%, 5% and 1%). E12, and E24. E96 series are high in cost as
It's a 3D printable enclosure that takes all of your E24 series resistors. check it with a known 1% resistor near the values you will test (I have 5 values of .1% resistors in a box on the The IEC Publication 60063: Preferred number series for resistors and capacitors specifies the preferred values in the E24 series, which is the most often used. The E24 series is for resistors with a 5% tolerance precision.Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ±5%, and E24+E96 series for resistors with a tolerance of ±1%. The values of the E24 / E96 series are in accordance with "IEC publication 60063" 3-Digits Marking (1% : 0603)
