Toroide windings calculator
Voltage / Current: Iron powder
Al value:
Desired value:

- This calculator calculates the number of windings on a toroide.
- Select the material of the toroide: iron powder or ferrite.
- Input: the Al value and the desired value in uH (iron powder) or mH (ferrite).
- For iron powder, the formula is: N = 100 x SQR(L[uH] / Al).
- For ferrite, the formula is: N = 1000 x SQR(L[mH] / Al).
