Ferrite Magnetic zobe inductance ya kasu zuwa manganese-zinc ferrite zobe da nickel-zinc ferrite zobe. Dangane da kayan da aka yi amfani da su, kayan da aka kayyade kuma sun bambanta. Zoben maganadisu na nickel-zinc ferrite an yi shi ne da ƙarfe, nickel, da zinc oxides ko gishiri, kuma ana yin su ta hanyar fasahar yumbu na lantarki. Zoben Magnetic na manganese-zinc ferrite an yi shi da ƙarfe, manganese, zinc oxides da gishiri, kuma ana yin shi ta hanyar fasahar yumbu na lantarki. Ainihin iri ɗaya ne a cikin kayan aiki da matakai, kawai bambanci shine cewa kayan biyu, manganese da nickel, sun bambanta. Waɗannan abubuwa ne daban-daban guda biyu waɗanda ke da tasiri daban-daban akan samfuri ɗaya. Manganese-zinc kayan suna da babban ƙarfin maganadisu, yayin da nickel-zinc ferrite suna da ƙarancin ƙarfin maganadisu. Manganese-zinc ferrite za a iya amfani da a aikace-aikace inda mitar aiki kasa da 5MHz. Nickel-zinc ferrite yana da babban juriya kuma ana iya amfani dashi a mitar mitar 1MHz zuwa ɗaruruwan megahertz. Sai dai inductor na yau da kullun, don aikace-aikacen da ke ƙasa da 70MHz, rashin ƙarfi na kayan manganese-zinc ya sa ya zama mafi kyawun zaɓi; don aikace-aikace daga 70MHz zuwa ɗaruruwan gigahertz, ana ba da shawarar kayan nickel-zinc. Manganese-zinc ferrite bead ana amfani dashi gabaɗaya a cikin kewayon mitar kilohertz zuwa megahertz. Zai iya yin inductor, masu canza wuta, masu tacewa, kawunan maganadisu da sandunan eriya. Za a iya amfani da zoben Magnetic nickel-zinc ferrite don yin muryoyin maganadisu don masu canjin tsaka-tsaki, kawuna na maganadisu, sandunan eriya na gajeriyar igiyar ruwa, inductance reactors, da na'urorin haɓakar maganadisu. Kewayon aikace-aikacen da balagaggen samfur sun fi Mn-Zn ferrite zoben maganadisu. Da yawa. Idan aka gauraya duniyoyi guda biyu, ta yaya za ku bambanta su? An bayyana takamaiman hanyoyi guda biyu a ƙasa. 1. Hanyar dubawa ta gani: Saboda Mn-Zn ferrite gabaɗaya yana da ingantacciyar ma'auni, manyan hatsin kristal, da ɗan ƙaramin tsari, galibi baki ne. Nickel-zinc ferrite gabaɗaya yana da ƙarancin lalacewa, hatsi masu kyau, tsari mara kyau, da sau da yawa launin ruwan kasa, musamman lokacin da zafin jiki ya yi ƙasa yayin aikin samarwa. Dangane da waɗannan halaye, zamu iya amfani da hanyoyin gani don rarrabewa. A wuri mai haske, idan launin ferrite baƙar fata ne kuma akwai ƙarin lu'ulu'u masu ban mamaki, to ainihin shine manganese-zinc ferrite; idan ka ga ferrite launin ruwan kasa ne, haske ya dushe, kuma barbashi ba su da ban mamaki, Magnetic core shine nickel-zinc ferrite. Hanya na gani hanya ce mai sauƙi, wadda za a iya ƙware bayan wani adadin aiki. Tsarin inductance na zobe na Magnetic 2. Hanyar gwaji: Wannan hanyar ita ce mafi aminci, amma tana buƙatar wasu kayan gwaji, kamar babban mitar juriya, mitar Q mita mai girma, da sauransu. 3. Gwajin matsa lamba.
