Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov khoom siv hluav taws xob tau dhau los ua ib yam khoom tseem ceeb hauv tib neeg lub neej txhua hnub.Cov khoom siv hluav taws xob tau nruab nrog ntau yam khoom siv hluav taws xob sib txawv, xws li ceramic capacitors.
1. Dab tsi yog ceramic capacitor?
Ceramic capacitor (ceramic condenser) siv lub siab dielectric tas li ceramic li dielectric, tshuaj tsuag nyiaj txheej ntawm ob sab ntawm ceramic substrate, thiab tom qab ntawd cov nyiaj zaj duab xis yog ci ntawm qhov kub thiab txias raws li cov electrode, cov hlau lead yog welded ntawm electrode, thiab Qhov saum npoo yog coated nrog tiv thaiv enamel los yog encapsulated nrog epoxy resin.Nws cov duab feem ntau yog nyob rau hauv daim ntawv ntawm ib daim ntawv, tab sis kuj muaj lub raj zoo, lub voj voog thiab lwm yam duab.
Ceramic capacitors siv nyob rau hauv hluav taws xob teb muaj qhov zoo ntawm qhov me me, siab tiv taus voltage, thiab zoo zaus.Nrog rau kev txhim kho thiab kev vam meej ntawm kev tshawb fawb thiab thev naus laus zis, ceramic capacitors tau dhau los ua cov khoom siv hluav taws xob tsis tseem ceeb rau cov khoom siv hluav taws xob.
2. Vim li cas ceramic capacitors "qav"?
Thaum siv cov khoom siv hluav taws xob, qee zaum koj yuav hnov suab nrov.Txawm hais tias lub suab me me, koj tseem tuaj yeem hnov yog tias koj ua tib zoo mloog.lub suab no yog dab tsi?Vim li cas qhov no suab thaum siv cov khoom siv hluav taws xob?
Qhov tseeb, lub suab no yog tshwm sim los ntawm ceramic capacitors.Vim lub siab dielectric tas li ntawm ceramic capacitors, cov khoom tsim muaj zog expansion thiab deformation nyob rau hauv qhov kev txiav txim ntawm ib tug sab nraud hluav taws xob teb, uas yog hu ua piezoelectric nyhuv.Kev ua nruj ua tsiv thiab kev cog lus ua rau saum npoo ntawm lub rooj tsav xwm hauv Circuit Court kom vibrate thiab emit suab.Thaum lub vibration zaus ntog nyob rau hauv ntau yam ntawm tib neeg hnov (20Hz ~ 20Khz), lub suab nrov yuav raug generated, uas yog hu ua "howling".
Txawm hais tias nws yog lub khoos phis tawj lossis lub xov tooj ntawm tes, cov kev xav tau ntawm cov khoom siv hluav taws xob tau nce siab dua, yog li ntau tus MLCC capacitors tau txuas nrog tib lub zog ntawm lub zog hluav taws xob network, thiab nws yooj yim rau xuav thaum tus qauv tsim txawv txav. los yog lub load ua hauj lwm hom yog txawv txav.
Cov ntsiab lus saum toj no yog vim li cas ceramic capacitors "squeak".
Xaiv cov chaw tsim khoom txhim khu kev qha thaum yuav cov khoom siv ceramic tuaj yeem zam ntau yam teeb meem tsis tsim nyog.JEC thawj cov chaw tsim khoom tsis tsuas yog muaj tag nrho cov qauv ntawm ceramic capacitors nrog lav zoo, tab sis kuj muaj kev txhawj xeeb tom qab muag.JEC cov chaw tsim khoom tau dhau ISO9001: 2015 kev tswj hwm kev tswj hwm daim ntawv pov thawj;JEC kev nyab xeeb capacitors (X capacitors thiab Y capacitors) thiab varistors tau dhau daim ntawv pov thawj ntawm ntau lub teb chaws;JEC ceramic capacitors, zaj duab xis capacitors thiab super capacitor yog nyob rau hauv txoj kab nrog qis carbon ntsuas.
