Cov Heroes zais ntawm wireless tshuab
Thaum koj tso cov yeeb yaj kiab lossis hu xov tooj, microwave ferrite cores ua haujlwm zoo li invisibret cov ntaub ntawv yog qhov tseem ceeb tshaj plaws hauv cov khoom siv hluav taws xob hauv cov khoom siv niaj hnub no.
Lawv yog dab tsi?
Microwave ferrite cores yog polycrystalline ceramics ua rau cov hlau oxia (fe₂o₃) ua ke nrog rau lwm cov hlau thiab manganese} Thaum magnetized los ntawm DC teb, lawv nthuav tawm ob lub superpowers:
Tsis-Qhov Rov Los Yej Soj Ntsuam(Cov phiajcim ntws tau zoo dua hauv ib qho kev coj)
Cov Txheej Txheem Txhawb Hluav Taws Xob(xws li kho cov teeb tsa lub teeb ntev)
Lawv cov lus dag nyob hauv cov tshuab hluav taws xob tig hauv cov pob zeb sib nqus - xav txog txhua qhov taw qhia hauv Unison [{{2}
Vim li cas cov tshuab tshuab uas hlub lawv
Nqi:60-80}}% pheej yig dua li cov huab cua sib npaug-inductors [^ 2]
Performance:Cov zaus ntau zaus 1MHz -30 ghz nrog permeability ntawm 150-1000
Qhov ruaj khov:Ua haujlwm ntawm 150℃+ yam tsis muaj kev nyuaj siab (saib thermal nkhaus hauv qab)
Tiag tiag-ntiaj teb khawv koob
Hauv koj lub smartphone ib leeg, ferrite cores enable:
✅ 5g teeb liab kev cais
Wireless Themfging Efficiency
✅ Suab nrov hauv lub koob yees duab
Cov chaw tsim khoom loj xws li Samsung thiab Huawei Siv cov duab ferrite (xws li trapezoidal cores) kom txuag tau chaw hauv cov khoom siv hauv compact [^].
Xaiv txoj cai tseem ceeb
Xav txog peb yam no:
Zaus phim(zoo li lub tsev xov tooj cua))
Lub Zog Tuav Tes(ntsuas hauv MW /M³)
Coefficient(Kev ruaj khov hla cov haujlwm ua haujlwm)
Pro tip: NiZn ferrites work best for high-frequency applications (>100mHz), Thaum Mnzn exhels ntawm qis dua zaus [^ 4] {2.
Lub neej yav tom ntej zoo li sib nqus
Nrog rau 5g nthuav dav thiab iot kev loj hlob, lub ntiaj teb ferrite kev ua lag luam yog npaj kom mus txog graphene-doped ferrites cog lus txawm tias kev ua tau zoo dua.
