Hoʻokaʻawale ʻia ka inductance magnetic ring i ka manganese-zinc ferrite apo a me ka nickel-zinc ferrite apo. Ma muli o ka mea i hoʻohana ʻia, ʻokoʻa ka mea calcined. Hana ʻia ke apo magnetic nickel-zinc ferrite me ka hao, nickel, a me ka zinc oxides a i ʻole nā ​​paʻakai, a hana ʻia e ka ʻenehana seramika uila. ʻO ka manganese-zinc ferrite magnetic ring i hana ʻia i ka hao, manganese, zinc oxides a me nā paʻakai, a hana ʻia hoʻi e ka ʻenehana seramika uila. Hoʻokahi like lākou i nā mea a me nā kaʻina hana, ʻo ka ʻokoʻa wale nō ʻo nā mea ʻelua, manganese a me ka nickel. ʻO kēia mau meaʻokoʻaʻelua i loaʻa nā hopena likeʻole ma ka huahana hoʻokahi. Loaʻa i nā mea manganese-zinc ke kiʻekiʻe o ka magnetic permeability, aʻo ka nickel-zinc ferrites he haʻahaʻa haʻahaʻa. Hiki ke hoʻohana ʻia ka manganese-zinc ferrite i nā noi kahi i haʻahaʻa ai ke alapine hana ma mua o 5MHz. Loaʻa i ka nickel-zinc ferrite ka resistivity kiʻekiʻe a hiki ke hoʻohana ʻia ma ka laulā alapine o 1MHz a hiki i nā haneli megahertz. Koe wale no nā inductors mode maʻamau, no nā noi ma lalo o 70MHz, ʻo ka impedance o nā mea manganese-zinc ke koho maikaʻi loa; no nā noi mai 70MHz a hiki i nā haneli gigahertz, ʻōlelo ʻia nā mea nickel-zinc. Hoʻohana maʻamau ʻia ʻo Manganese-zinc ferrite bead ma ke alapine o ka kilohertz a me ka megahertz. Hiki ke hana i nā inductors, transformers, kānana cores, magnetic poʻo a me nā lāʻau antenna. Hiki ke hoʻohana ʻia nā apo magnetic nickel-zinc ferrite no ka hana ʻana i nā cores magnetic no nā mea transformers mid-peripheral, nā poʻo magnetic, nā koʻokoʻo antenna hawewe pōkole, nā reactors inductance i hoʻopaʻa ʻia, a me nā mea hoʻonui saturation magnetic. ʻOi aku ka maikaʻi o ka pae noi a me ka ulu ʻana o ka huahana ma mua o nā apo magnetic ferrite Mn-Zn. Nui. Ke hui pū ʻia nā ʻano ʻelua, pehea ʻoe e ʻike ai ma waena o lākou? ʻElua mau ʻano kikoʻī i wehewehe ʻia ma lalo nei. 1. ʻO ke ʻano o ka nānā ʻana: No ka mea, ʻoi aku ka kiʻekiʻe o ka Mn-Zn ferrite, ʻeleʻele pinepine. ʻO ka nickel-zinc ferrite maʻamau ka haʻahaʻa haʻahaʻa, nā kīʻaha maikaʻi, ka hale porous, a ʻeleʻele pinepine, ʻoi aku ka haʻahaʻa o ka mahana sintering i ke kaʻina hana. Ma muli o kēia mau hiʻohiʻona, hiki iā mākou ke hoʻohana i nā ala ʻike e ʻike ai. Ma kahi ʻālohilohi, inā ʻeleʻele ka waihoʻoluʻu o ka ferrite a ʻoi aku ka nui o nā kristal nani, a laila ʻo ke kumu he manganese-zinc ferrite; inā ʻike ʻoe he ʻeleʻele ka ferrite, ʻeleʻele ka ʻulaʻula, a ʻaʻole hoʻolohilohi nā ʻāpana, ʻo ke kumu magnetic he nickel-zinc ferrite. ʻO ke ʻano hiʻohiʻona he ʻano ʻano koʻikoʻi, hiki ke hoʻopaʻa ʻia ma hope o kekahi mau hana. ʻO ke kauoha inductance ring magnetic 2. ʻO ke ala hoʻāʻo: ʻoi aku ka hilinaʻi o kēia ʻano, akā pono ia i kekahi mau mea hoʻāʻo, e like me ke kiʻekiʻe kūpaʻa mika, kiʻekiʻe pinepine Q mika, a pēlā aku.
