EIA resistor table

Tabella delle resistenze EIA.

The Electronic Industries Alliance (EIA) provides specific standards for resistor values. Availability of resistor value is also determined by the size of tolerances that is known as E series. The number following the "E" specifies the number of logarithmic steps per decade.

The series are as follows:

E6 20% tolerance (now seldom used)

E12 10% tolerance

E24 5% tolerance

E48 2% tolerance

E96 1% tolerance

E192 0.5, 0.25, 0.1% and higher tolerances
