EXAMPLE:

  • N (Number of Turns) = 10
  • s (Spacing) = 100 mils
  • Di (Inner Diameter) = 100 mils
  • Do (Outer Diameter) = 400 mils

The resulting Inductance will be 0.5 mH / mils.

Circular Spiral Inductor Equation

The inductor which is shaped like a circular spiral is known as a circular spiral inductor.

The following equation or formula is used to calculate the inductance of a circular spiral inductor:
