# Inductor on PCB as a meander structure.

In addition to coils on PCB in the form of a square or circular spirals also there is in the form of a meander. Meander line inductors have lower inductance per unit area than coil inductors. For the calculation of such inductive element is this plugin. The inductance of the inductor is calculated by the following empirical formula:

where:

*L*– inductance of meander (µH)*N*– number of turns*a*– length of a lead (mm)*h*– height of the meander (mm)*d*– width of the meander (mm)*b*– half of the height h (mm)*W*– width of the printed strip (mm)

This expression has been obtained by fitting according to a great number of fabricated inductors

Inductance is calculated with accuracy ±12%.
