Dielectrics yog siv ua lub capacitor khaws cia lub zog. Cov khoom siv dielectric nyob rau hauv lub transformer yog siv los ua ib qho insulator thiab ua kom txias. Txhawm rau txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob semiconductor, cov khoom siv siab permittivity dielectric yog siv.
Dab tsi yog cov khoom siv dielectric feem ntau siv?
Hauv kev xyaum, feem ntau cov khoom siv dielectric yog khoom. Piv txwv suav nrog porcelain (ceramic), mica, iav, yas, thiab cov oxides ntawm ntau yam hlauQee cov kua thiab roj tuaj yeem ua cov khoom siv hluav taws xob zoo. Cov huab cua qhuav yog ib qho zoo heev dielectric, thiab yog siv nyob rau hauv qhov sib txawv capacitors thiab qee hom kab sib kis.
cov khoom siv dielectric siv nyob qhov twg?
Cov ntaub ntawv Dielectric yog siv ntau yam kev siv xws li: Cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob(lub luag haujlwm rau lub zog cia khoom ntawm lub cuab yeej) High-K / low-K cov ntaub ntawv dav siv. nyob rau hauv Semiconductors los txhim kho kev ua tau zoo thiab txo cov cuab yeej loj (qhov twg K yog hais txog permittivity lossis dielectric tas li)
Dielectric siv rau dab tsi?
Ib cov khoom siv dielectric yog siv txhawm rau cais cov paib hluav taws xob ntawm lub capacitorCov khoom siv insulating no tau txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.
Dab tsi yog dielectric muab ib qho piv txwv?
Dielectrics yog cov khoom tsis ua. Lawv yog cov ntaub ntawv insulating thiab yog cov conductors phem ntawm hluav taws xob tam sim no. Cov ntaub ntawv dielectric tuaj yeem tuav cov nqi hluav taws xob thaum lub zog tsawg tsawg hauv daim ntawv kub. Piv txwv ntawm dielectric yog Mica, yas, iav, plooj (porcelain) thiab ntau yam hlau oxides
