Cov thev naus laus zis tseem ceeb ntawm siab -voltage capacitors tig los ntawm kev ua tiav cov hom phiaj xws li high voltage withstand peev xwm, miniaturization, ncua lifespan, thiab siab ntseeg siab, nrog rau kev tawg ntawm cov khoom tseem ceeb, kev tsim qauv, thiab kev tsim khoom.
Hais txog cov khoom siv hluav taws xob ceramic, cov khoom siv tshwj xeeb los ntawm cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob siab tshaj -voltage rwb thaiv tsev yog siv; Cov hom muaj xws li Class I ceramics (piv txwv li, C0G/NP0), Class II ceramics (xws li, X7R, X5R, Y5V), thiab Class III ceramics (piv txwv li, Y5V). Los ntawm kev tshawb fawb thiab kev tsim cov khoom siv ceramic tshiab, qhov hluav taws xob tiv thaiv kev ua tau zoo ntawm -voltage ceramic capacitors tau ua kom zoo dua qub, ua kom lawv ua tiav 150% ntawm cov peev txheej uas muab los ntawm cov kev daws teeb meem ib txhij txo lub cev ntim los ntawm 40%. Kev txhim kho hauv nyias- cov txheej txheem tsim cov yeeb yaj kiab thiab cov khoom tsim tau zoo ib yam ua rau kev txhim kho qhov muaj peev xwm tiv taus thiab txo qhov ntev; los ntawm kev siv ultra-thin metallized polypropylene zaj duab xis ua ke nrog cov txheej txheem winding siab heev, siab -voltage film capacitors tau raug tsim tawm uas-nyob rau hauv qhov sib npaug voltage tiv taus cov xwm txheej- pom qhov txo qis ntawm kwv yees li 30% piv rau cov khoom qub.
Rau cov roj insulating, cov ntaub ntawv xws li SAS-40E thiab M/DBT yog ua haujlwm; cov roj capacitor no yog biodegradable, chlorine -dawb (tsis yog -PCB), thiab muaj kev tiv thaiv zoo rau ib nrab tawm. Tsis tas li ntawd, kev siv cov ionic kua electrolytes tshiab tshiab - uas muaj cov ntsiab lus siab dua thiab cov tshuaj lom neeg ruaj khov zoo dua piv rau cov khoom siv electrolytes-txhim kho lub neej ua haujlwm ntawm lub capacitor.
