Cheap nanocrystalline cores from Zhuhai King Magnetics

[Poppy]

Hi


does anybody have experiences with cheap china-cores like these ones?


Nanocrystalline C Cores, Nanocrystalline C Cores direct from Zhuhai King Magnetics Technology Co., Ltd. in CN


They can't be as bad as they are (comparably) cheap, right?



Thank you!
