rl low pass cutoff calculator online

Use rl low pass cutoff calculator online for resistance ohm, inductance H. Series RL network with output across the resistor. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter resistance ohm. Set inductance H. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
resistance ohmMain input. Positive values. 100
inductance HOption. Positive values. 0.01

Calculation method

cutoff_Hz = resistance_ohm/(2*pi*inductance_H) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply rl low pass cutoff calculator to the case below, keeping the displayed units and assumptions. Series RL network with output across the resistor.

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

  • Series RL network with output across the resistor. 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.
