Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Inductance 1 (H)

Required number input.

Inductance 2 (H)

Required number input.

Calculate the total inductance of two inductors connected in series. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Total inductance (H)

The resulting total inductance returned as a number.

• Inductor calculations depend on core material, air gap, turns, frequency, waveform, temperature, DC bias, copper resistance, skin and proximity effects, fringing, and saturation definition. Small-signal inductance and nominal current rating may not describe switching operation.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Parallel Inductors

  Calculate the total inductance of two inductors connected in parallel.

• Series Capacitors

  Calculate the total capacitance of two capacitors connected in series.

• Parallel Capacitors

  Calculate the total capacitance of two capacitors connected in parallel.
