Greetings to readers of my blog! Today I will tell you how to make inductance with the necessary parameters. In my case it was a toroidal coil that should work in my power supply. First I found a copper wire, which I removed from the old transformer.
The wire has a diameter of 0.66 mm. This I measured with a digital caliper.
Further, to get the inductance, it must be done on the ferrite ring. I found this from some disassembled device. Then I measured the ferrite ring, I needed an outer diameter, inner diameter and height.
To calculate the usable inductance, I used an excellent online calculator. I entered the measured parameters to get 20 microhenry (μH).
Thus, the length of the wire was 58 cm, and the number of turns 17. I neatly wrapped the wire on the ring.
It seems to be not bad, do you think? To measure the resulting inductance, I used some tester.
As you can see, I got 0.02mH * 1000 = 20μH. This magic works :)
Note that in this calculator there are other calculations, for other inductances on ferrite rods or air coils.
Thank you for your attention, I hope my information be useful.
With the best wishes, @gleb-jeglov aka Evgeny.

Я делал LC-фильтр для блока питания. В целом же, такие катушки могут служить для разных целей, различные фильтры, преобразователи, контуры. Иногда проще самому сделать индуктивность, чем ждать пока придет готовая с али :)

Thank you! I did not know about it, maybe it's because I'm not so long ago on this site.

No, this is not suitable for voltage conversion as a transformer.
