Hom-C Interface Electrostatic Protection Device Yuav tsum xaiv li cas?

Hom-C Interface Electrostatic Protection Device Yuav tsum xaiv li cas?

Hom-C yog USB3.1 tus qauv hauv qab lub interface tshiab. Raws li qhov tseeb USB specification, USB3.1 specification, uas yog launched los ntawm cov tuam txhab loj xws li Intel, yuav ua rau kom cov ntaub ntawv hloov ceev mus rau 10Gbps, thiab cov tshiab technology kuj siv ib tug ntau npaum li cas cov ntaub ntawv encoding system thiab muab cov ntaub ntawv muaj txiaj ntsig zoo, sib xws nrog USB connectors thiab cables uas twb muaj lawm.

e Hom-C interface txhawb nqa plug-and-play thiab kub-swapping, yog li qib ntawm kev tiv thaiv zoo li qub yuav tsum siab. Cov cuab yeej tiv thaiv ESD yuav tsum muaj qhov zoo ntawm cov lus teb ceev, tsis tshua muaj peev xwm, me me, pob tsawg thiab tsis tshua muaj hluav taws xob.

Tam sim no, yuav luag tag nrho cov USB interface yuav raug siv rau cov khoom siv tiv thaiv electrostatic, FAE engineers yog qhov yooj yim tshaj plaws los tswj cov khoom siv hluav taws xob, cov khoom siv tiv thaiv hluav taws xob thiab cov ntsiab lus xaiv thiab lwm yam. Circuit Court tiv thaiv ntaus ntawv xaiv tsis muaj teeb meem, nkag siab txog kev tiv thaiv cov khoom, qib kev tiv thaiv yuav paub tau yog xaiv cov raj xa tawm, TVS diode, varistor lossis PTC tus kheej rov qab fuse, ESD ESD, ua raws li ntau yam Circuit Court. kev tiv thaiv Lub hauv paus ntsiab lus xaiv ntawm cov cuab yeej thiab cov kev ua haujlwm voltage, tam sim no thiab lwm yam los txiav txim seb tus qauv kawg tuaj yeem ua tau.

Hom-C interface electrostatic tiv thaiv cov khoom xaiv thaum kawg raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom xaiv tus qauv ESD tsim nyog. Ob lub hauv paus ntsiab lus hauv qab no yuav tsum tau ua thaum xaiv thiab muab cov cuab yeej tiv thaiv electrostatic:

1, Vdrw Ntau dua los yog sib npaug rau Circuit Court ntawm kev khiav hauj lwm voltage

2, raws li daim ntawv thov chaw nres nkoj, kev tiv thaiv qib xaiv thaj siab lossis diode, raws li kev sib kis ntau zaus los xaiv tus nqi capacitance, qhov ntau zaus, cov cuab yeej yuav muaj tus nqi qis dua, tus nqi ntau dhau yuav ua rau muaj teeb meem. pob ntawv poob, Tus kheej yuav tsum xaiv qhov tsim nyog tshaj ESD.

ESD-hom ESD tiv thaiv cov cuab yeej ntawm Hom-C interface yuav tsum ua kom tau raws li peb qhov yuav tsum tau ua:

1, ESD tiv thaiv Cheebtsam ntawm parasitic capacitance nws tus kheej yuav tsum yog me me, thiaj li yuav xyuas kom meej tias cov ntaub ntawv kis tau tus mob tsis yog pob ntawv poob, tsis cuam tshuam rau hom-C interface kis tus nqi;

2, cov khoom tiv thaiv ntawm ESD kam rau ua yuav tsum siab, tsawg kawg kom tiv taus IEC 61000-4-2 tiv tauj hom 8kV ESD foob pob.

3, kuj yog qhov tseem ceeb tshaj plaws uas yuav tsum tau muaj cov khoom tiv thaiv thaum lub sij hawm ESD qhov kev tshwm sim yuav tsum muaj tsawg txaus los txwv cov ntaub ntawv kis tau tus mob.
