Series and Parallel Capacitor Calculator
Enter capacitances in microfarads. This tool computes ideal series and parallel capacitance.
Enter the values above and select Calculate result.
Formula
Cparallel = ΣCi; 1 / Cseries = Σ(1 / Ci)
Worked example
Two 10 µF capacitors in parallel make 20 µF. Two identical 10 µF capacitors in series make 5 µF.
Engineering notes
Ceramic MLCC capacitance can fall significantly under DC bias. ESR, leakage, tolerance and voltage rating are not included.
Always compare calculated values with the actual component datasheet, tolerance stack-up, operating temperature and circuit conditions before applying them to hardware.
