Utilize our free Ferrite Toroid Calculator to swiftly determine either the inductance of your toroid with a known number of turns or the required turns for a target inductance. Ideal for RF choke and filter design, this tool simplifies inductor calculations for electronics enthusiasts and engineers.
Formula:
To calculate Inductance (L) in microhenries (µH) from AL Value (nH/turn²) and Number of Turns (N):
L = AL × (N / 1000)2
To calculate Number of Turns (N) from Desired Inductance (L) in microhenries (µH) and AL Value (nH/turn²):N = 1000 × √(L / AL)
Where:- L = Inductance (µH)
- AL = Inductance Factor (nH/turn²)
- N = Number of Turns
