E pili ana i ka mānoanoa saturation flux, ʻoi aku ka kiʻekiʻe o ka ferrosilicon ma mua o ka senddust. Eia nō naʻe, ʻoi aku ka maikaʻi o ka senddust, i hōʻike ʻia i ka saturation palupalu ʻoi aku ka maikaʻi, negligible core poho, paʻa wela a me ke kumu kūʻai haʻahaʻa o ka hoʻohana. Hiki i nā Inductors e hoʻohana ana i ka sentdust magnetic powder cores ke hoʻopau i nā kumu maikaʻi ʻole i hoʻokumu ʻia e ka ea ea o ke apo magnetic ferrite.

nā kikoʻī penei:

1. He emi a like paha ka 0.5T ma lalo o ka hapalua o ka ferrite o ka ferrite. ʻO ia hoʻi, ma lalo o ka leo like, ʻoi aku ka haʻahaʻa o ka mālama ʻana i ka ikehu o ka ferrite ma mua o ka senddust.

2. He emi loa ka pale wela o ka ferrite i ka senddust. Hoʻemi nui ʻia ka mānoanoa magnetic saturation magnetic flux o ferrite ma lalo o nā kūlana wela kiʻekiʻe, ʻoiai ʻaʻole loli nui ka saturation magnetic flux density o senddust ma lalo o nā kūlana wela kiʻekiʻe.

3. Loaʻa i ka Ferrite nā hiʻohiʻona o ka wikiwiki a me ka piha. Inā ʻoi aku ia ma mua o ke kumukūʻai palekana o kēia manawa, hiki iā ia ke hoʻohaʻahaʻa i ka hana inductance ma ke ʻano holoʻokoʻa, ʻoiai ʻo Sendust nā hiʻohiʻona o ka palupalu a me ka piha a hiki ke kū i nā koina o kēia manawa.

4. He kūpono loa nā cores Sendust no nā inductors kānana mālama ikehu i ka hoʻololi ʻana i nā lako mana. Ke hoʻohālikelike ʻia me ka air-gap ferrite a i ʻole ka pauka hao o ka nui like a me ka permeability, hoʻouna nā cores me ka saturation flux kiʻekiʻe hiki ke hāʻawi i ka ikehu mālama kiʻekiʻe.

5. I ka wā e pono ai e hele i ka uila kamaʻilio nui me ka hana ʻole ʻana i nā inductors kānana leo piha, hiki i ka hoʻohana ʻana i ka sentdust core ke hōʻemi i ka nui o ka kānana pūnaewele. No ka mea, he emi iho ka helu o ka huli ana ma mua o ka ferrite, sendust no hoi he magnetostriction coefficient kokoke i ka nul, oia hoi, he malie loa i ka hana o ka walaau a i ole i keia manawa ma ka pūnaewele i loko o ka audible frequency range.

6. High magnetic flux density a haʻahaʻa kumu poho hiʻona i sentust cores kūpono loa no ka mana kumu calibration kaapuni a unidirectional drive noi, e like me flyback transformers a me pulse transformers.
