Jan 30, 2019 · Generally, choose a toroidal core with a diameter large enough to fit the required number of turns in a single layer. Usually bigger cores are used for lower frequencies to achieve sufficient magnetizing inductance with fewer turns. Also, the inside diameter of the toroid should not be excessive (which leads to higher leakage inductance). 6.

Toroidal inductors are used where large inductance are required at low frequency levels. These are insulated coils in ring shape. As toroid inductors have more number of turns it can carry more currents.The wire gauge affects inductance only indirectly, since the wire size determines how many turns you can wind on a given toroid and, of course, inductance is proportional to the number of turns. I have a Toroid Core listed here: LINK , i have T130-52 . Now i need to build an inductor out of this toroid. How do i determine which wire to wound, and how many turns would give me what inductance?
