Series Inductor Calculator Formula

Understand the math behind the series inductor calculator. Each variable explained with a worked example.

Formulas Used

Total Inductance

total_l = l1_mh + l2_mh + l3_mh

Variables

VariableDescriptionDefault
l1_mhInductor L1(mH)10
l2_mhInductor L2(mH)22
l3_mhInductor L3 (0 to skip)(mH)0

How It Works

Series Inductors

L_total = L1 + L2 + L3 + ...

Inductances add directly in series, just like resistors in series. Assumes no mutual coupling.

Worked Example

10 mH and 22 mH in series.

l1_mh = 10l2_mh = 22l3_mh = 0
  1. 01L_total = 10 + 22 = 32 mH
