## Calculator of inductance from AL value and number of turns

If AL value is known then the inductance can be calculated as:

 $$L = A_L ⋅ N^2$$ (H)
AL value =       number of turns N = (unitless)

L=

Note: the AL value is typically specified just in the units of inductance e.g. (nH), without the square turns. If this is the case just select the corresponding unit, e.g. (nH/t2).

(See also the calculator of AL value from inductance and number of turns).
