rc low pass frequency response calculator online

Use rc low pass frequency response online for frequency Hz, resistance ohm, capacitance F. Unloaded first-order RC low pass. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter frequency Hz. Set resistance ohm, capacitance F. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
frequency HzMain input. Positive values. 1000
resistance ohmOption. Positive values. 1000
capacitance FOption. Positive values. 0.000001

Calculation method

gain = 1/sqrt(1+(2*pi*frequency_Hz*resistance_ohm*capacitance_F)^2); phase_deg = -atand(2*pi*frequency_Hz*resistance_ohm*capacitance_F) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply rc low pass frequency response to the case below, keeping the displayed units and assumptions. Unloaded first-order RC low pass.

RC Low Pass Frequency Response — worked case

Settings: resistance ohm: 1000; capacitance F: 0.000001

Input:

1000

Calculated result for these inputs:

Output:

{
  "gain": 0.15717672547758987,
  "phase_deg": -80.95693892096232
}

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Unloaded first-order RC low pass. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
