Thaum nws los txog rau MLCC (multilayer ceramic capacitor) capacitor) capacitor) capacitor) capacitor) capacitor) capacitor) capacitors, ib qho tseem ceeb kom xav txog yog qhov sib npaug series tiv thaiv (ESR). Tus ESR ntawm capacitics hais txog kev tiv thaiv sab hauv ntawm lub capacitor. Hauv lwm lo lus, nws ntsuas npaum li cas yooj yim tus capacitor ua lwm yam tam sim no (AC). Nkag siab txog ESR ntawmMlCC muaj peev xwmyog qhov tseem ceeb hauv ntau daim ntawv thov hluav taws xob, tshwj xeeb tshaj yog cov uas yuav tsum tau ua haujlwm ruaj khov thiab siv hluav taws xob tsawg.
ESR ntawm MLC captitor cuam tshuam los ntawm ntau yam, xws li cov khoom muaj pes tsawg leeg, qauv, thiab qhov loj me.MlCC muaj peev xwmFeem ntau yog tsim los ntawm ntau txheej ntawm cov khoom siv ceramic stacked, nrog txhua txheej sib cais los ntawm hlau electrodes. Cov khoom siv ceramic ntawm cov capacitors feem ntau yog kev sib txuas ntawm titanium, zirconium, thiab lwm cov hlau oxides. Cov ntaub ntawv no tau raug xaiv los muab cov txiaj ntsig siab muaj peev xwm thiab cov kev cuam tshuam qis ntawm cov haujlwm siab.
Txo estr, cov chaw tsim khoom lag luam feem ntau ua cov thev naus laus zis hauv kev tsim khoom. Ib qho txheej txheem no yog suav nrog cov khoom siv coj ua, xws li nyiaj lossis tooj liab, hauv daim ntawv ntawm cov khoom noj ua dag. Cov lus qhuab qhia no tau siv los tsim cov ntawv hluav taws xob uas txuas cov txheej txheem ceramic, yog li txo tag nrho ERR. Ib qho ntxiv, cov chaw tsim khoom tuaj yeem thov ib cov khoom siv nyias nyias ntawm cov khoom siv rau saum npoo ntawmMlcc capatorkom ntxiv txo ESR.
ESR ntawm MLC captitor ntsuas yog ntsuas hauv Ohms thiab yuav sib txawv raws li daim ntawv thov. Txo estr tseem ceeb yog feem ntau ntshaw vim tias lawv qhia tau zoo dua conduction thiab qis zog poob. Tsis muaj estr Capitors yog qhov zoo dua rau cov ntawv thov kev ua tau zoo, xws li cov khoom siv loj thiab cov khoom siv hluav taws xob. Lawv muab kev ruaj khov zoo dua thiab muaj peev xwm ua tau kev hloov pauv ceev hauv voltage yam tsis muaj kev poob qis.
Txawm li cas los xij, nws yuav tsum tau sau tseg tiasMlCC muaj peev xwmnrog cov ESR tsis tshua muaj kuj yuav muaj kev txwv. Hauv qee cov ntawv thov, ib qho ESR uas tsis tshua muaj peev xwm ua rau tsis muaj kev cuam tshuam thiab kev ua haujlwm tsis ruaj khov. Yog li ntawd, nws yog qhov tseem ceeb rau ua tib zoo xaiv MLC caportitics nrog ESR tus nqi haum rau cov kev cai tshwj xeeb ntawm Circuit Court.
Ntxiv rau, ESR ntawmMlCC muaj peev xwmHloov sijhawm sijhawm vim muaj qee yam xws li kev laus thiab qhov kub thiab txias. Kev laus ua rau tus ESR kom nce, cuam tshuam rau tag nrho cov kev ua tau zoo ntawm Circuit Court. Cov xwm txheej no yuav tsum tau txiav txim siab thaum tsim cov tshuab hluav taws xob ua kom ntseeg tau tias kev ntseeg tau ntev ntev thiab ruaj khov.
Hauv cov ntsiab lus, ESR ntawm MLC Captitor Ua tau lub luag haujlwm tseem ceeb hauv kev txiav txim siab txog cov yam ntxwv hluav taws xob. Qhov no yog ib qho tseem ceeb uas tseem ceeb los txiav txim siab thaum xaiv cov ntawv thov hluav taws xob rau ntau yam khoom siv hluav taws xob. MLCC lub peev xwm nrog cov ESR tau txhim kho kev ua kom zoo thiab ruaj khov thiab yog qhov zoo rau kev loj dua. Txawm li cas los xij, ESR tus nqi yuav tsum tau sib npaug nrog cov kev cai tshwj xeeb ntawm Circuit Court kom ntseeg tau tias kev ua tau zoo thiab kev ntseeg tau.
