Inductors in Series Calculator

Summary

Enter up to 10 inductor values to calculate their total series inductance instantly.

How it works

1. Enter the value for each inductor and select its unit (H, mH, µH, or nH).
2. Click "Add Inductor" to add more inductors — up to 10 total.
3. The calculator converts all values to henries and sums them.
4. The total inductance is displayed in the most readable unit.
5. The series formula with your values is shown below the result.

Use cases

• Design filter circuits with a specific total inductance.
• Verify inductor configurations on a PCB schematic.
• Calculate equivalent inductance when combining off-the-shelf inductors.
• Prototype RF and audio circuits requiring precise inductance values.
• Teach or learn the series inductance addition rule.
