- This calculator finds combinations of standard E-series (between 10Ω and 1MΩ) to create arbitrary values. - You can enter the required resistance from 0.0025 to 4000 kΩ. - Solutions using up to 4 components are given. The requested value is always excluded from the solution set.<br> Optionally up to two additional values can be excluded in case of component availability problems. Solutions are given in the following formats: R1 + R2 +...+ Rnresistors in series R1 | R2 |...| Rnresistors in parallel R1 + (R2|R3)...any combination of the above
