A focused electronics tool that finds series, parallel, and mixed capacitor combinations for a target capacitance.

Landing page captured for the 2026-09-08 issue.

Field notes

The page accepts a target capacitance in pF, nF, or µF and pairs it with an E-series selection ranging from E6 through E96. It describes searching series, parallel, and mixed arrangements, then ranking the resulting combinations by percentage error. The documented input range runs from 0.5pF to 10000µF, while worked examples show both the reciprocal series formula and the simpler additive parallel formula.
