Cov khaub thuas sib chwv sib tshooj , tseem hu ua hom khaub thuas sib xyaw, feem ntau siv rau hauv kev hloov pauv hloov pauv rau hauv koos pij tawj hluav taws xob kom dhau kev sib cuam tshuam ntawm hom kev cuam tshuam. tiv thaiv cov xaim hluav taws xob vim los ntawm kev kub ceev fais fab kab los ntawm kev xa mus rau sab nraud khoom hluav taws xob.
Vim li cas hom chokes yog EMI tiv taus?
Txhawm rau kom nkag siab qhov no zoo dua, nws yog ib qho tseem ceeb uas koj yuav tsum pib soj ntsuam kev tsim kho ntawm hom kev siv chokes.
Qes qis lim rau USB hom hom chokes, La thiab Lb yog hom hom chokes.Peb coils muaj qhov txhab ntawm tib lub kauj hluav taws xob nrog tib tus xov tooj ntawm lem thiab theem kaum sab xis (thim rov qab ntawm lub coil inductor) .Txawm li no, thaum txhua qhov qub nyob rau hauv lub Circuit Court hla dhau ntawm cov khaub thuas sib tshooj caj dab, xws li cov dej ntws tam sim no tsim cov chaw sib nqus hauv cov lus qhia sib luag hauv cov kauj inductor muaj cov theem tib lub kaum ntse ntse thiab cov sib cuam tshuam sib txawv.Txawm qhov no, txhua cov ntaub ntawv teeb liab tam sim no cuam tshuam los ntawm coil resistors (thiab ib qho me me ntawm kev poob siab nqus vim qhov taug kev inductance); Thaum hom hom tam sim no ntws los ntawm lub kauj, vim hais tias hom hom tam sim no nyob rau hauv tib qho kev sib tw, lub kauj yuav tsim ib qho chaw sib nqus hauv tib qho kev coj, thiab kev sib hloov ntawm cov kauj. yuav nthuav dav zuj zus, ua rau lub kauj hlau coj zoo li tus yam ntxwv ntawm lub siab tsis haum, yog li ua rau lub zog poob siab poob siab.
Yog li no, qhov teeb meem thoob plaws-hom tam sim no yuav raug nplua los ntawm cov coefficient kom ua tiav lub hom phiaj ntawm lub lim.Qhov qhov tseeb, yog tias ib qho kawg ntawm qhov lim qis no txuas nrog lub teeb liab cuam tshuam thiab lwm qhov kawg tau txuas nrog lub cuab yeej cuam tshuam thiab tshuab, La thiab C1, Lb thiab C2 yuav tsim ob txheej kev lim dej tsis tshua muaj zog uas muaj peev xwm tswj tau cov hom hluav taws xob tsis xws luag hluav taws xob teeb liab cuam tshuam rau hauv txoj hauv kev mus rau lub cim hluav taws xob tsawg heev.
Lub Circuit Court tsis tuaj yeem tsuas yog txwv tsis pub cov kis ntawm cov hluav taws xob sab nraud ntawm hluav taws xob, tabsis tseem ua rau lub teeb liab ntawm lub tshuab hluav taws xob tshwm sim los ntawm cov kab hluav taws xob nws tus kheej hauv kev ua haujlwm ntawm cov coefficient, yog li muaj txiaj ntsig txo qhov kev raug mob ntawm lub teeb liab cuam tshuam rau lub zog tensile.
Nyob rau tam sim no, ib qho kev ua haujlwm hom choke coil tsim los ntawm lub tuam txhab muaj qhov zoo ntawm cov suab nrov nrov ntau dua kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv, cov hom choke hom tsis zoo, cov paib tsis zoo xa mus coefficient, me me, siv yooj yim, zoo stability, yooj yim siv thiab zoo .Txheej siv nyob rau hauv ob qhov sib npaug suab cov khoom ntsuas hluav taws xob, ntau zaus hloov pauv, cov yam ntxwv tsis cuam tshuam kev hloov pauv, ua kom muaj kev hloov pauv thiab tsis sib npaug, thiab lwm yam.
Kuj tseem muaj usb nrog ferrite core common-mode choke coil / EMI lim inductance, muaj ntau yam kev sib tw winding, suab nrov zoo kev tiv thaiv thiab kev ntsuas kev tiv thaiv, muaj cov hom suab nrov tshaj plaws thiab muaj tsawg hom txawv suab nrov cov ntaub ntawv teeb liab, txwv tsis pub cuam tshuam lub teeb liab tsawg cov sib txawv cov ntaub ntawv suab nrov, lub nrawm nrawm ntawm cov ntaub ntawv lub teeb liab tsis txawv txav, loj me, kev nyab xeeb zoo, kev siv yooj yim, qhov zoo ntawm cov khoom siv zoo.
USB cable rau tus kheej lub khoos phis tawm thiab khoom siv hluav taws xob, IEEE1394 cov kab txuas rau DVC thiab TV teeb cov npov saum toj, thiab cov cim suab rau LCD kev khiav hauj lwm thiab cov haujlwm ua haujlwm nyob hauv qab.
Qhov ntawd yog kev qhia txog lim hla qis rau hom khaub thuas caj pas. Vam tias koj nyiam nws! Peb yog chaw tsim khoom tsim khoom , yog tias koj xav yuav khoom lossis hloov kho, txais tos sab laj ~
