Thaum nws los txog rau MLCC (Multilayer Ceramic Capacitor) capacitors, ib qho tseem ceeb uas yuav tsum tau xav txog yog qhov sib npaug Series Resistance (ESR). ESR ntawm lub capacitor yog hais txog qhov kev tiv thaiv sab hauv ntawm lub capacitor. Hauv lwm lo lus, nws ntsuas tau yooj yim npaum li cas lub capacitor ua alternating tam sim no (AC). Nkag siab txog ESR ntawmMLCC capacitoryog qhov tseem ceeb hauv ntau daim ntawv thov hluav taws xob, tshwj xeeb tshaj yog cov uas xav tau kev ua haujlwm ruaj khov thiab siv hluav taws xob tsawg.
ESR ntawm MLCC capacitor cuam tshuam los ntawm ntau yam, xws li cov khoom siv, qauv, thiab qhov loj me.MLCC capacitorfeem ntau yog tsim los ntawm ntau txheej txheej ntawm cov khoom siv ceramic stacked, nrog txhua txheej sib cais los ntawm cov hlau electrodes. Cov khoom siv ceramic xaiv rau cov capacitors feem ntau yog kev sib xyaw ntawm titanium, zirconium, thiab lwm yam hlau oxides. Cov ntaub ntawv no tau ua tib zoo xaiv los muab cov txiaj ntsig muaj peev xwm siab thiab qis impedance ntawm cov khoom siv siab.
Txhawm rau txo ESR, cov tuam ntxhab feem ntau siv cov thev naus laus zis sib txawv hauv cov txheej txheem tsim khoom. Ib qho txheej txheem zoo li no yog suav nrog cov khoom siv hluav taws xob, xws li nyiaj lossis tooj liab, hauv daim ntawv ntawm cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob no yog siv los tsim cov khoom siv hluav taws xob uas txuas cov txheej txheem ceramic, yog li txo qis ESR tag nrho. Tsis tas li ntawd, cov neeg tsim khoom tuaj yeem siv cov txheej nyias nyias ntawm cov khoom siv hluav taws xob rau saum npoo ntawm cov khoomMLCC capacitortxhawm rau txo ESR ntxiv.
ESR ntawm MLCC capacitor yog ntsuas hauv ohms thiab yuav txawv nyob ntawm daim ntawv thov. Tsawg ESR qhov tseem ceeb feem ntau yog qhov xav tau vim tias lawv qhia tau tias muaj kev ua tau zoo dua thiab qis zog poob. Tsawg ESR capacitors zoo dua rau cov ntawv thov uas xav tau kev ua haujlwm siab, xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Lawv muab kev ruaj ntseg zoo dua thiab ua haujlwm tau zoo thiab tuaj yeem tswj cov kev hloov pauv sai hauv qhov hluav taws xob yam tsis muaj qhov poob loj.
Txawm li cas los xij, nws yuav tsum tau sau tseg tiasMLCC capacitornrog ESR qis heev kuj yuav muaj kev txwv. Hauv qee daim ntawv thov, ESR uas qis dhau tuaj yeem ua rau tsis xav tau resonance thiab ua haujlwm tsis ruaj khov. Yog li ntawd, nws yog ib qho tseem ceeb kom ua tib zoo xaiv MLCC capacitor nrog ESR tus nqi tsim nyog rau cov kev cai tshwj xeeb ntawm Circuit Court.
Tsis tas li ntawd, ESR ntawmMLCC capacitorhloov raws sij hawm vim muaj tej yam xws li kev laus thiab kub hloov. Kev laus ntawm lub capacitor ua rau ESR nce, cuam tshuam rau tag nrho kev ua haujlwm ntawm lub voj voog. Cov yam tseem ceeb no yuav tsum tau xav txog thaum tsim cov tshuab hluav taws xob kom ntseeg tau ntev thiab ruaj khov.
Hauv cov ntsiab lus, ESR ntawm MLCC capacitor plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov yam ntxwv hluav taws xob. Qhov no yog ib qho tseem ceeb rau kev txiav txim siab thaum xaiv cov capacitors rau ntau yam kev siv hluav taws xob. MLCC capacitors nrog qis ESR txhim kho kev ua tau zoo thiab ruaj khov thiab zoo tagnrho rau cov kab hluav taws xob ntau zaus. Txawm li cas los xij, tus nqi ESR yuav tsum sib npaug rau cov kev cai tshwj xeeb ntawm Circuit Court kom ntseeg tau tias kev ua tau zoo thiab kev ntseeg siab.
