Air core inductance and Q value online calculator

The following is an air-core coil inductance calculation software, which can be used for the calculation of the inductance of the air-core coil and the calculation of the inductance Q value.

Coil dimensions

Air core coil inductance calculation formula:L=(d2n2)/(l + 0.45d)


Input data

Coil diameter  d :  m
Coil length    l :  m
Number of turns  n : 







MHz : 







(Q is only used to calculate Q value)

Calculated

Inductance value       L :  µH
Inductance Q value Q:
