Standard Capacitance & Resistance Values

STANDARD DECADE RESISTANCE/CAPACITANCE VALUES (pdf)
The following table lists four established number series which are used as preferred values in electronic design. Each series is shown under an associated value of tolerance %. The numbers under the ± 10 % column is known as the E12 Series because there are 12 standard values within a decade range. ± 2 % and ± 5 % utilize the E24 Series, ± 1 % uses E96 and ± 0.1 %, ± 0.25 % and ± 0.5 % use E192.

Use of standard values is encouraged because stocking programs are designed around them.
However, intermediate values can be special ordered where permitted. Consult factory.

Standard resistance values are obtained from the decade table by multiplying by powers of 10. As an example, 13.3 can represent 13.3 Ω, 133 Ω, 1.33 kΩ, 13.3 kΩ, 133 kΩ, 1.33 MΩ. Standard capacitance values are highlighted.

Standard Resistor Calculator 


This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard values for the given tolerance.

Resistor Value  (Ohms) 
Percentage 1%, 5%, 10%


 
EIA Number Tolerance
E12   10%
E24 5%
E96 1%
The EIA E number is the number of logarithmic steps.
For example, for E12 has twelve steps between any power.
