📝 Description of the video: Hello everyone. Finally, I got around to filming such a useful video for you. This includes not only winding and calculation instructions, but also useful tips for beginners. I hope you appreciate it)
But as they say without jambs anywhere. Or in another way - smart thoughts come after a fight. And so, I forgot to mention an equally important info. It concerns the permeability of the core.
The power core should have a permeability in the region of 2000-2200 nm. Other values, this is no longer power ferrite.
How to find out the permeability of the core? yes, very simple.
Full instructions are on this site: https://coil32.ru/calc/ferrite-permea...
You just need to wind the turns and measure the inductance of the winding, and then the online calculator will calculate everything for you.
I hope you are not too offended by such a jamb of mine :D
