E-series defined in IEC 60063 are a widely accepted system of preferred
|
|
numbers for electronic components. Available values are approximately
|
|
equally spaced in a logarithmic scale.
|
|
|
|
E12: 1,0 1,2 1,5 1,8 2,2 2,7 3,3 3,9 4,7 5,6 6,8 8,2
|
|
E6: 1,0 - 1,5 - 2,2 - 3,3 - 4,7 - 6,8 -
|
|
E3: 1,0 - - - 2,2 - - - 4,7 - - -
|
|
E1: 1,0 - - - - - - - - - - -
|

|
|
This calculator finds combinations of standard E-series components to
|
|
create arbitrary values. You can enter the required resistance from 0,0025 to 4000 kOhm.
|
|
Solutions using up to 3 components are given.
|
|
|
|
If a closer solutions is needed, the 4R checkbox option will give solutions
|
|
using 4 components for the E12 series only. This option
|
|
may take longer to compute.
|
|
|
|
It is also possible to specify up to two values to exclude from the solution if these
|
|
component values are not available
|
|
|
|
Solutions are given in the following formats:
|
|
|
|
R1 + R2 +...+ Rn resistors in series
|
|
R1 | R2 |...| Rn resistors in parallel
|
|
R1 + (R2|R3)... any combination of the above
