Kusiyana pakati pa Manganese Zinc ndi Nickel Zinc| KHALANI BWINO

Njira inductance ferrite imagawidwa mn-Zn ferrite mphete ndi mphete ya Ni-Zn ferrite. Malinga ndi zida zomwe zimagwiritsidwa ntchito, zida za calcined ndizosiyana. Nickel-zinc ferrite maginito mphete amapangidwa makamaka ndi oxides kapena mchere chitsulo, faifi tambala ndi nthaka ndipo amapangidwa ndi electronic ceramic ndondomeko. Mphete za manganese-zinc ferrite zimapangidwa ndi oxides ndi mchere wachitsulo, manganese ndi zinc, komanso zimapangidwa ndiukadaulo wamagetsi a ceramic. Iwo ali ofanana muzinthu ndi ndondomeko, kusiyana kokha ndiko kuti manganese ndi faifi tambala ndizosiyana. Ndizinthu ziwiri zosiyanazi zomwe zimakhala ndi zotsatira zosiyana kwambiri pa chinthu chomwecho.

Zida za Mn-Zn zimakhala ndi kuthekera kwakukulu, pomwe ma ferrite a Ni-Zn ali ndi mwayi wochepa. Ma ferrite a Mn-Zn atha kugwiritsidwa ntchito pamapulogalamu pomwe ma frequency ogwiritsira ntchito amakhala otsika kuposa 5MHz. Ma ferrite a Ni-Zn ali ndi resistivity kwambiri ndipo amatha kugwiritsidwa ntchito pafupipafupi kuyambira 1MHz mpaka mazana a MHz. Kupatula ma inductors amtundu wamba, kutsekeka kwa zida za mn-Zn kumapangitsa kukhala chisankho chabwino kwambiri pakugwiritsa ntchito pansi pa 70MHz, pomwe zida za Ni-Zn zimalimbikitsidwa kuti zigwiritsidwe ntchito kuyambira 70MHz mpaka mazana a gigahertz. Mphete za manganese-zinc ferrite nthawi zambiri zimagwiritsidwa ntchito pafupipafupi kuchokera ku kilohertz kupita ku megahertz. Itha kupanga inductors , zosinthira, zosefera, mitu yamaginito ndi ndodo za mlongoti. Mphete za Ni-Zn ferrite zitha kugwiritsidwa ntchito popanga ma core of the medium-cycle transformers, mitu ya maginito, ndodo za mlongoti wa mafunde afupiafupi, makina opangira ma inductance ndi maginito amplifiers. Mitundu yogwiritsira ntchito komanso kukhwima kwa mphete za Ni-Zn ferrite ndizabwinoko kuposa mphete za mn-Zn ferrite.

Kodi mumasiyanitsa bwanji pakati pa makoko awiri akasakanizidwa pamodzi?

1. Njira yowonera

Chifukwa ma ferrite a mn-Zn nthawi zambiri amakhala ndi ma permeability apamwamba, njere zazikulu, mawonekedwe ophatikizika ndipo nthawi zambiri amakhala akuda. Nthawi zambiri, ma ferrite a Ni-Zn amakhala otsika pang'ono, njere zabwino, mawonekedwe a porous ndipo nthawi zambiri amakhala a bulauni, makamaka pamene kutentha kwa sintering kumakhala kochepa popanga. Malingana ndi makhalidwe amenewa, tikhoza kuwasiyanitsa ndi maso. M'malo omwe kuwala kumakhala kowala, ngati mtundu wa ferrite ndi wakuda ndipo pali kuwala kowala, ndiye kuti pachimake ndi manganese-zinc ferrite; ngati muwona kuti ferrite ndi yofiirira, kuwala ndi mdima, ndipo tinthu tating'ono tating'ono tating'ono tating'onoting'ono tating'onoting'ono ta nickel-zinc ferrite. Njira yowonera ndi njira yovuta kwambiri, yomwe imatha kuzindikirika pambuyo poyeserera pang'ono. Maginito mphete inductance kuyitanitsa.

2. Njira yoyesera

Njirayi ndi yodalirika, koma imafunika zida zoyesera, monga mita yotsutsa kwambiri, ma frequency a Q mita ndi zina zotero.

Zomwe zili pamwambazi ndikuyambitsa kusiyana pakati pa Manganese Zinc ndi Nickel Zinc wa ferrite magnetic ring inductors. ngati mukufuna kudziwa zambiri za inductors, chonde omasuka kulankhula nafe.
