RC Filter Calculator
Calculate RC low-pass and high-pass filter cutoff frequency from resistance and capacitance values. Shows angular frequency, time constant, rise time, and signal attenuation at the -3dB point.
How to Use RC Filter Calculator
Enter resistance value and unit (Ω, kΩ, MΩ) and capacitance value and unit (F, mF, µF, nF, pF). Click Calculate to see the cutoff frequency, time constant, angular frequency, and rise time.
Step-by-Step Instructions
- Enter resistance value and select unit
- Enter capacitance value and select unit
- Click Calculate Cutoff Frequency
- View frequency, time constant, and rise time
