Capacitors yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.Muaj ntau hom capacitors, nrog rau kev ruaj ntseg capacitors, zaj duab xis capacitors, ceramic capacitors, super capacitors, thiab lwm yam. Lawv tau dav siv hauv cov khoom siv hluav taws xob xws li TV, xov tooj cua, thiab xov tooj ntawm tes.Txawm li cas los xij, capacitors tuaj yeem ua tsis tiav vim qee yam, xws li ceramic capacitors.Muaj peb hom kev ua tsis tiav ntawmceramic capacitor: thermal shock tsis ua hauj lwm;twist rupture tsis ua hauj lwm;raw khoom tsis ua hauj lwm.
Thermal Shock Failure
Thaum lub sij hawm tsim cov ceramic capacitors, cov khoom siv raw rau kev ua cov ceramic capacitors txawv, thiab lawv cov thermal expansion coefficient thiab thermal conductivity kuj txawv.Thaum qhov kub thiab txias heev, nws yooj yim rau thermal shock thiab rupture, uas ua rau tsis ua hauj lwm ntawm ceramic capacitors.Feem ntau, nyob ze ntawm qhov sib cuam tshuam ntawm qhov raug tshem tawm thiab cov ceramic termination, qhov twg lub tshuab nro yog generated, nws yog feem ntau ua rau thermal shock thiab tawg.
Distortion thiab Repture
Ceramic capacitor raug xaiv thiab muab tso nrog kev pab ntawm cov cuab yeej.Thaum lub sij hawm xaiv thiab qhov chaw txheej txheem, lub siab ntawm cov cuab yeej nruab nrab yog concentrated nyob rau hauv ib qho chaw, ua rau muaj kev kub siab.Qhov saum npoo ntawm lub ceramic capacitor yog qhov yooj yim rau cov kab nrib pleb, thiab cov kab nrib pleb yuav kis mus rau cov kev taw qhia ntawm lub zog siab.Ntawm qhov tod tes, ceramic capacitor yuav poob.
Ua tsis tiav ntawm cov khoom siv raw
1) Qhov tsis ua hauj lwm ntawm electrodes thiab rupture ntawm txoj kab sib txuas yog feem ntau yog tshwm sim los ntawm qhov sib txawv ntawm cov ceramics, los yog qhov sib txawv ntawm cov txheej txheem dielectric thiab cov electrode, uas ua rau cov txheej txheem dielectric ntawm cov electrodes tawg thiab ua rau latent to. kev kub ntxhov.
2) Cov yam ntxwv ntawm combustion rupture yog perpendicular mus rau lub electrode thiab feem ntau yog los ntawm ntug los yog davhlau ya nyob twg ntawm lub electrode.Yog hais tias cov ruptures zoo li ntsug, lawv yuav tsum tau tshwm sim los ntawm combustion.
Thaum muas ceramic capacitors, nws yog advisable xaiv ib tug trustworthy manufacturers kom tsis txhob muaj teeb meem tsis tsim nyog.JYH HSU (los yog Dongguan Zhixu Electronics) tsis tsuas yog muaj tag nrho cov qauv ntawm ceramic capacitors nrog lav zoo, tab sis kuj muaj kev txhawj xeeb tom qab muag.Peb cov chaw tsim khoom yog ISO 9000 thiab ISO 14000 tau ntawv pov thawj.Yog tias koj tab tom nrhiav rau cov khoom siv hluav taws xob, txais tos hu rau peb.
