Kev siv ntawm Soft ferrites

Mos ferrites muaj ntau yam khoom zoo kawg nkaus uas ua rau lawv haum rau ntau yam kev siv. Ib qho tseem ceeb tshaj plaws ntawm cov mos ferrites yog lawv cov kev tiv thaiv siab, uas tso cai rau lawv kom tawg lub zog nyob rau hauv daim ntawv ntawm tshav kub. Cov cuab yeej no ua rau lawv tsis muaj nuj nqis nyob rau hauv cov ntawv thov uas txo qis zog poob yog qhov tseem ceeb, xws li high-frequency transformers thiab inductors. Tsis tas li ntawd, cov ferrites mos muaj qhov coercivity tsawg, tso cai rau lawv yooj yim magnetized thiab demagnetized nrog tsawg zog tawm tswv yim. Cov cuab yeej no muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov xws li kev cuam tshuam hluav taws xob (EMI) thiab cov lim suab nrov.

Qhov zaus-dependent permeability ntawm mos ferrites yog lwm yam khoom tseem ceeb. Nws txawv nrog zaus, ua cov ferrites mos zoo heev nyob rau hauv daim ntaub ntawv uas muaj alternating tam sim no. Xov tooj cua zaus (RF) transformers coj kom zoo dua ntawm cov cuab yeej no, qhov chaw mos ferrites pab nyob rau hauv impedance txuam thiab teeb liab kis tau tus mob. Curie kub uas cov khoom ferrite poob nws cov khoom ferromagnetic kuj yog qhov tseem ceeb. Mos ferrites muaj qhov kub Curie qis, tso cai rau lawv ua haujlwm tau zoo ntawm chav tsev kub thaum tsis txhob poob lub zog vim cua sov ntau dhau.

Cov ntawv thov ntawm Soft Ferrites: Cov ferrites mos muaj cov ntawv thov hauv ntau qhov kev lag luam, pab txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm ntau yam khoom siv. Ib qho ntawm lawv cov kev siv tseem ceeb yog hauv inductors thiab transformers rau cov khoom siv fais fab. Lawv cov kev poob qis qis, siab permeability, thiab qis coercivity tso cai rau kev tsim cov khoom sib nqus thiab cov khoom sib nqus zoo. Qhov no yog qhov tseem ceeb rau cov khoom siv hluav taws xob niaj hnub no uas qhov loj thiab lub zog ua haujlwm tseem ceeb heev.

Nyob rau hauv xyoo tas los no, muaj ntau qhov kev nce qib hauv thaj tsam ntawm cov ferrites mos. Cov kws tshawb fawb tau ua haujlwm los txhim kho cov khoom ntawm cov ntaub ntawv los ntawm cov txheej txheem kev ua haujlwm tshiab thiab kev hloov kho muaj pes tsawg leeg. Piv txwv li, nanocrystalline soft ferrites nthuav tawm cov khoom sib nqus zoo dua vim lawv cov qauv zoo. Cov ntaub ntawv no txo ​​cov tub ntxhais poob thiab txhim kho cov yam ntxwv ntawm cov zaus zaus, ua rau lawv tsim nyog rau kev siv ntau zaus xws li wireless charging thiab RF kev sib txuas lus.
