Inductance/Turns Calculator

How is Inductance and Turns Calculator: AL, L and N calculated?

Use L(µH) = AL(nH/N²) × N²/1000; N = √[1000L(µH)/AL]. Calculate inductance from AL and turns, or solve turns from target inductance. Check nH/turn² units, rounding and DC-bias limits.

How do I calculate this example: AL = 100 nH/N², N = 10?

L = 10 µH. This is a calculated example under the model stated above; it is not a measured component specification.

Which units does Inductance and Turns Calculator: AL, L and N use?

µH, nH/N², N. Convert prefixes before substituting values; keep the input and output units attached to every number.

Is nominal inductance constant at every current?

No. DC bias, temperature and measurement frequency can change inductance. Use the manufacturer’s curves for the selected part rather than assuming a constant value.

Should I round the required turns up or down?

Evaluate both practical integer values with L = ALN², then check inductance tolerance, bias and available winding space. Rounding alone does not validate the design.

Can this result predict temperature rise?

No. Temperature rise also requires loss data, mounting, airflow and a validated thermal model. A calculated electrical value is not a thermal qualification.
