To use the toroid winding calculator
- Click the Material Type (ferrite or iron powder) of the core that you
- In the Inductance
box, type the desired inductance (units are
millihenries for ferrite cores, or
for iron powder cores).
- In the Core Size drop-down box, select the
size of the core that you are using (for example 'T-50').
- In the Material Number drop-down box, select
the material number of the core that you are using (for example
- Click Calculate.
Example To calculate
the number to turns to get 1
uH with a T-50-2 core, select Iron
Powder, a core size of T-50, and a material
number of 2
(Red). The calculation shows that 14 turns produce 0.96 uH.
