Find Standard Resistor and Capacitor Values January 21, 2006
This javascript calculator finds the closest standard resistor (or capacitor) value in each of the IEA series. Use this, and get rid of that tattered old standard decade resistance table taped to your cubicle and put a nice photo there instead!
| Desired Value: |
| IEA Series | Closest Value | Error |
| E6 | ||
| E12 | ||
| E24 | ||
| E48 | ||
| E96 | ||
| E192 |
Which IEA series applies to the various component types?
- E6: most capacitors, some inductors
- E12: some capacitors, 10% resistors
- E24: 5% resistors
- E48: 2% resistors
- E96: 1% resistors
- E192: 0.5%, 0.25%, 0.1% resistors

Thanks!
Is there any way you can show me how you make a calculation for capacitors? Do you have any equation you can share? Thanks for your help and your web side - it’s been great.

Shah,
I’m not sure what kind of calculation you are looking for, but if it is a formula to find the closest capacitor value, I don’t have one. This calculator uses lookup tables for the E6 and E12 capacitor series as they don’t seem to follow a formula. If there is some other kind of calculation you are looking for, let me know.

Thanks for the info
It is a very useful resource for the engineering student
Great tool for any engineer that performs filter realizations for multiple impedance de-normalizations. With this tool it is very fast and easy to locate the best part match vs. Exx series.
Thanks Tony!

thanks for timely help!
Thanks for this calculator but if you want to find closest resister in series or palallel from standard resistors try this calculator http://www.coolcircuit.com/tools/resistor_closest/index.php
Thanks for the resistor calculator!
