72. E series
The EIA “E” series specify the preferred values for passive components such as resistors and capacitors. The number following the “E” specifies the number of logarithmic steps per decade. The table below is normalized for the decade between 10 and 100 for E3 to E24, between 100 and 1,000 for E48 to E96. Note that E series is same as the one standardized by JIS C 5063.
