| Nov 16, 2023 at 2:32 | comment | added | zdanman | Thank you for your insight. What permeability is to be considered here other than 2300? Where else would 2300 be utilized? Are these inductance equations insufficient? | |

| Nov 16, 2023 at 1:17 | comment | added | Michal Podmanický | I don’t think you can use 2300 as permeability in this equation. Open Ferrite (huge air gap) cores increases inductance usually 10-th times comparing to air cores. Btw, 150uH for 40 turns seems ok to me. | |
