Ferrite maginito mphete inductance imagawidwa mu manganese-zinc ferrite mphete ndi nickel-zinc ferrite mphete.Kutengera ndi zinthu zomwe zimagwiritsidwa ntchito, zinthu za calcined ndizosiyana.Mphete ya maginito ya nickel-zinc ferrite imapangidwa makamaka ndi chitsulo, faifi tambala, ndi zinc oxides kapena mchere, ndipo amapangidwa ndi ukadaulo wamagetsi wa ceramic.Mphete ya manganese-zinc ferrite imapangidwa ndi chitsulo, manganese, zinc oxides ndi mchere, komanso imapangidwa ndiukadaulo wamagetsi a ceramic.Iwo ali ofanana mu zipangizo ndi ndondomeko, kusiyana kokha ndiko kuti zipangizo ziwiri, manganese ndi faifi tambala, ndizosiyana.Ndizinthu ziwiri zosiyanazi zomwe zimakhala ndi zotsatira zosiyana kwambiri pa chinthu chomwecho.Zipangizo za manganese-zinc zimakhala ndi maginito apamwamba kwambiri, pamene ma ferrite a nickel-zinc ali ndi maginito otsika.Manganese-zinki ferrite atha kugwiritsidwa ntchito ngati ma frequency opareshoni ndi otsika kuposa 5MHz.Nickel-zinc ferrite imakhala ndi kukana kwambiri ndipo imatha kugwiritsidwa ntchito pafupipafupi 1MHz mpaka mazana a megahertz.Kupatula ma inductors wamba, pazogwiritsa ntchito pansi pa 70MHz, kutsekeka kwa zinthu za manganese-zinc kumapangitsa kukhala chisankho chabwino kwambiri;pakugwiritsa ntchito kuchokera ku 70MHz mpaka mazana a gigahertz, zida za nickel-zinc zimalimbikitsidwa.Manganese-zinc ferrite bead nthawi zambiri amagwiritsidwa ntchito pama frequency a kilohertz mpaka megahertz.Itha kupanga ma inductors, zosinthira, zosefera, mitu yamaginito ndi ndodo za mlongoti.Mphete za maginito za Nickel-zinc ferrite zitha kugwiritsidwa ntchito kupanga maginito osinthira apakati, mitu ya maginito, ndodo za mlongoti wamafunde afupiafupi, makina opangira ma inductance reactor, ndi maginito amplifiers.Mtundu wa ntchito ndi kukhwima kwazinthu ndizopambana kuposa mphete za maginito za Mn-Zn ferrite.Zambiri.Pamene mikangano iwiri ikasakanizidwa, mumasiyanitsa bwanji pakati pawo?Njira ziwiri zenizeni zafotokozedwa pansipa.1. Njira yoyendera: Chifukwa chakuti ferrite ya Mn-Zn nthawi zambiri imakhala ndi mpweya wochepa kwambiri, njere zazikulu za krustalo, komanso kapangidwe kake kakang'ono, nthawi zambiri imakhala yakuda.Nickel-zinc ferrite nthawi zambiri imakhala yotsika pang'ono, njere zabwino, mawonekedwe a porous, ndipo nthawi zambiri zimakhala zofiirira, makamaka kutentha kwa sintering kumakhala kochepa panthawi yopanga.Malingana ndi makhalidwewa, tikhoza kugwiritsa ntchito njira zowonetsera kuti tisiyanitse.Pamalo owala, ngati mtundu wa ferrite ndi wakuda ndipo pali makhiristo owoneka bwino, ndiye kuti pachimake ndi manganese-zinc ferrite;ngati muwona kuti ferrite ndi yofiirira, kuwala ndi mdima, ndipo tinthu tating'ono tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono ta nickel-zinc ferrite.Njira yowonera ndi njira yovuta kwambiri, yomwe imatha kuzindikirika pambuyo pochita zambiri.Magnetic ring inductance order 2. Njira yoyesera: Njirayi ndi yodalirika, koma imafunika zida zoyesera, monga mita yotsutsa kwambiri, ma frequency Q mita, ndi zina zotero. 3. Mayeso opanikizika.
