Electronic Industries Association (EIA) and IEC publication 60063 specify standard values of resistors and other electronic components.
These values are logarithmically spaced in increments of 1/N of a decade, where N –
tolerance series, such as 96 for E96. Standard base values can be approximated by the following formula:
R=10i/N , where i=0,1,…, N-1.
For E96 (1%) series rounding the results from this formula to three significant digits yields exact 1% values. For other series, it will yield the values that in some cases differ from standard values due to rounding error. The table below shows the standard values for the decade between 100 and 1,000. To find standard values in other decades, multiply or divide the table value by powers of 10. Also see resistor color code calculator, color code chart.
