If you are estimating stability of feedback system, determining bandwidth or decoupling components for your circuit, RC time constant or cut-off frequency is one of essential parameters. This calculator will help you to evaluate cut-off frequency and time constant of RC circuit.

Enter two out of three values; resistance, capacitance or frequency.

You can also enter two values out of resistance, capacitance or time constant.

Get the rest calculated.

You can use scientific notation to enter data (example: 1.25e-3; 529.46e5)

Enter values and calculate
