Capacitive Reactance Calculator
Enter frequency in Hz and capacitance in µF. The ideal magnitude is reported in ohms; at 0 Hz its limiting value is infinite.
Ideal capacitor model only; ESR, ESL, self-resonance and real component impedance are not estimated. Every comparison uses the entered capacitance.
The report freezes submitted raw inputs and units.
Formula: Xc = 1 ÷ (2π × f × C × 10⁻⁶)
Result
| Frequency (Hz) | Ideal reactance (Ω) |

Common questions
What does the comparison table use?
Each entered frequency uses the same supplied component value. No frequencies are prefilled.
