Hauv cov chip hom inductor , cov khoom sib txawv tuaj yeem xaiv raws li tus yam ntxwv thiab qhov xav tau loj. Gv Electronics, lub tuam txhab nti inductor , qhia rau koj yuav ua li cas xaiv txoj cai COMmon-hom choke coil los ntawm cov yam ntxwv ntawm qhov pom.
Tej zaum koj yuav xav tau cov no ua ntej koj xaj
1. Yuav siv li cas sib txawv kis tau tus mob thiab hom hom choke coils
Ua ntej piav qhia txog cov yam ntxwv ntawm hom hom choke coils, cia peb ua ntej qhia lub tswv yim ntawm hom teeb liab thiab qhov sib txawv hom teeb liab.
Differential kis tau tus mob yog ib txoj kev siv rau high-ceev cov ntaub ntawv kis tau tus mob. Piv txwv li, MIPI? siv nyob rau hauv lub koob yees duab thiab zaub screen ntawm smartphones, HDMI?, DisplayPort, thiab USB ntawm computers yog tag nrho cov sib txawv txoj kev sib kis.
Nyob rau hauv ob kab ntawm qhov sib txawv kis tau tus mob, theem ntawm ib leeg (qhia qhov sib txawv ntawm qhov voltage waveform thiab tam sim no waveform) yog thim rov qab teeb liab kis tau tus mob.
Cov teeb liab no yog hu ua lub teeb liab sib txawv, thiab cov ntaub ntawv xa mus yog ua los ntawm cov teeb liab sib txawv. (Differential hom yog qee zaum hu ua hom qub). Piv nrog cov teeb liab sib txawv, kuj tseem muaj lub teeb liab hu ua hom teeb liab, uas yog kis tau rau tib theem hauv 2 kab.
Rau nti hom hom inductors rau cov kab teeb liab, cov teeb liab hom hom yog ib qho tsis xav tau teeb liab, uas yog, suab nrov, uas yog hu ua hom suab nrov.
Differential hom teeb liab sib xyaw nrog cov suab nrov hom. Thaum lub teeb liab sib txawv tau txais, qhov sib txawv hom teeb liab sib zog sib zog ua ke, thiab cov suab nrov hom sib txawv tshem tawm ib leeg. Txoj kev sib kis sib txawv zoo li no tsis tshua muaj kev cuam tshuam rau hom suab nrov.
Qhov sib txawv ntawm cov hluav taws xob sib kis tau pom ntawm qhov deb, thiab cov teeb liab sib txawv ntawm ib leeg. Lub sijhawm no, qhov sib txawv hom teeb liab tso tseg ib leeg tawm, thiab cov suab nrov hom sib zog sib zog. Ntawd yog, nws muaj kev cuam tshuam rau hom suab nrov ntawm qhov deb.
Thaum cov teeb meem zoo sib xws tshwm sim, hom hom choke coil txuas nrog rau hauv cov kab sib txawv ntawm cov kab sib txawv kom tshem tawm cov suab nrov nrov.
2. Kev nkag siab txog cov yam ntxwv ntawm hom hom choke coils
Qhov tseeb, qhov txawv hom suab nrov yog me ntsis txo vim yog hom hom choke coil. Tsis tas li ntawd, qhov sib txawv-hom thiab hom-hom teeb liab muaj kev txo qis vim muaj ntau zaus. Cov yam ntxwv ntawm xws li hom hom choke coil yog sawv cev los ntawm cov yam ntxwv zaus ntawm qhov sib txawv ntawm qhov kev tso qhov poob Sdd21 thiab cov hom kev ntxig teeb liab Scc21. (Sdd21 thiab Scc21 yog ib feem ntawm kev sib xyaw-hom 4-chaw nres nkoj S-tsis muaj)
Cov yam ntxwv zaus ntawm hom kev ntxig qhov poob Scc21. Qhov tob ntawm qhov ntxig qhov poob, qhov ntau dua qhov poob. Qhov siab dua qhov zaus ntawm qhov sib txawv hom teeb liab, qhov poob ntau dua. Hom hom kev ntxig tsis Scc21 yog qhov nkhaus nrog lub ncov, thiab cov nyhuv ntawm kev tshem tawm cov suab nrov hom sib txawv nyob ntawm qhov zaus.
Lub teeb liab zaus ntawm cov nti hom hom inductor rau cov kab teeb liab sib txawv nyob ntawm txoj kev sib tshuam, thiab hom hom choke coil kuj hloov raws li.
Seb hom hom choke coil yog qhov tsim nyog tuaj yeem txiav txim raws li qhov sib kis ntawm cov teeb liab waveform. Feem ntau, qhov kev txiav tawm zaus ntawm hom hom choke coil yog peb zaug ntawm cov teeb liab zaus ntawm qhov sib txawv ntawm qhov sib txawv. Lub thiaj li hu ua cutoff zaus yog qhov zaus ntawm qhov sib txawv hom kev nkag mus ua 3 dB.
Txawm li cas los xij, txawm tias nws tsawg dua 3 zaug, muaj ntau yam teeb meem hauv lub teeb liab waveform, thiab qhov no yog qhov siv tau zoo tshaj plaws. (Vim tus qauv ntawm cov teeb liab zoo xws li daim ntawv qhia perforation yog teev nyob rau hauv txhua qhov interface, nws yog thaum kawg txiav txim seb nws puas haum los yog tsis raws li tus qauv no)
Ntawm qhov tod tes, qhov teeb meem suab nrov thiab nws zaus sib txawv ntawm lub davhlau ya nyob twg mus rau lub davhlau ya nyob twg, thiab raws li cov yam ntxwv zaus ntawm qhov tsim nyog hom kev ntxig qhov poob hloov raws li.
Piv txwv li, thaum lub suab nrov tshwm sim uas ntau tshaj qhov txwv tus nqi teev tseg los ntawm tus qauv emission regulation, nws yog qhov zoo dua los xaiv ib qho uas muaj ntau hom kev ntxig poob hauv qhov zaus ntawm cov suab nrov ntawd.
Tsis tas li ntawd, hom suab nrov uas cuam tshuam los ntawm kev sib kis sib txawv tuaj yeem cuam tshuam rau nws tus kheej kev sib txuas lus wireless xws li LTE thiab Wi-Fi. Nws tuaj yeem txiav txim siab tias hom suab nrov ntawm tib zaus raws li kev sib txuas lus wireless tshwm sim, thiab lub kav hlau txais xov tau txais lub suab nrov no. Qhov no yog hu ua suppressed reception rhiab heev. Nyob rau lub sijhawm no, los ntawm kev ntxig ib hom choke coil, emission ntawm hom suab nrov tuaj yeem raug tshem tawm thiab kev txais tos rhiab heev tuaj yeem txhim kho.
Cov saum toj no yog kev taw qhia rau cov yam ntxwv ntawm SMD hom inductors. Yog tias koj xav paub ntau ntxiv txog SMD inductors, thov hu rau peb.
