Q: Ceramic capacitors raug cuam tshuam los ntawm kev laus phenomena
Ceramic capacitors raug cuam tshuam los ntawm kev laus tshwm sim cuam tshuam nrog kev hloov pauv hauv cov qauv siv lead ua dielectric, uas tshwm sim nws tus kheej raws li kev hloov pauv hauv cov khoom siv hluav taws xob thiab cov khoom siv dissipation tom qab thawj zaug tua ntawm cov khoom siv dielectric.Raws li cov qauv tsim, EIA Class I dielectric cov ntaub ntawv raug cuam tshuam tsawg heev thiab tau lees paub dav tias tsis muaj kev laus, thaum EIA Class II dielectric cov ntaub ntawv cuam tshuam me ntsis thiab EIA Class III cov ntaub ntawv zoo li cuam tshuam loj heev.Cov txheej txheem kev laus no tuaj yeem rov pib dua (lossis cov cuab yeej "de-aging") los ntawm qhov kub thiab txias tshaj qhov dielectric's Curie kub rau lub sijhawm ntev txaus kom tso cai rau cov qauv siv lead ua rov ua dua;qhov siab dua qhov kub, lub sijhawm luv dua.Txij li thaum Curie kub ntawm ntau ceramic dielectrics qis dua qhov uas tau ntsib nyob rau hauv ntau cov txheej txheem soldering, nws zoo li tias cov cuab yeej yuav muaj tsawg kawg yog ib nrab hnub nyoog thaum sib dhos.
Qhov kev laus tus cwj pwm no feem ntau yog qhia raws li qhov feem pua ntawm kev hloov pauv hauv lub peev xwm ntawm ib xyoo caum ntawm cov xuab moos, txheeb ze rau qhov ntsuas qhov ntsuas ntawm "qhov cua sov kawg," lub sijhawm kawg cov khoom siv tau rhuab saum nws Curie kub ntev txaus los hloov tag nrho nws cov siv lead ua. qauv.Hauv lwm lo lus, lub capacitor nrog kev laus ntawm (-) 5%, ntsuas ntawm 100uF hauv lub xeev "qhov cub tshiab", yuav tsum ntsuas kwv yees li 95,90 thiab 85uF tom qab 1, 10 thiab 100 teev tawm ntawm qhov cub. , raws.
Pom tseeb, qhov no ua rau cov lus nug ntawm qhov nominal capacitance ntawm cov khoom yuav tsum yog, thiab yog tias tus nqi hloov pauv tas li, cov khoom siv yuav raug siv rau ntawm lub txee txawm tias nws tsis tau siv hauv nws qhov qub ntim.Cov qauv kev lag luam EIA-521 thiab IEC-384-9 hais txog qhov teeb meem no, hauv paus ntsiab lus hais tias cov khoom yuav tsum ncav cuag nws qhov kev kam rau ua tus nqi 1000 teev (txog 42 hnub) tom qab cua sov kawg.Lub kaum xyoo tom ntej (10K thiab 100K teev) txhais mus rau me ntsis dhau 1 xyoo thiab me ntsis tshaj 11 xyoo.Txhawm rau kom muaj teeb meem ntxiv, cov txheej txheem kev laus tshwm sim ntawm qhov ntsuas kub ntawm qhov ntsuas kub;mus txog qhov kub ntawm Curie ntawm dielectric, qhov nce hauv cov cuab yeej ntsuas kub feem ntau ua rau cov txheej txheem kev laus.
Txij li thaum muaj hnub nyoog tshwm sim tuaj yeem ua rau cov khoom siv tshwm sim sab nraud ntawm lawv qhov kev cia siab, cov neeg tsim khoom thiab cov neeg soj ntsuam ntau lawm yuav tsum paub txog qhov tseeb;kev ntsuam xyuas ntawm cov khoom tshiab reflowed yuav tsum cia siab tias yuav muaj qhov muaj peev xwm siab dua me ntsis, thiab tus qauv tsim yuav tsum muaj cov npoo txaus kom haum rau kev ua haujlwm ntawm lub cuab yeej raws li nws muaj hnub nyoog.Lub zog hloov hluav taws xob hloov hluav taws xob yog ib qho piv txwv zoo ntawm qhov kev cuam tshuam no tuaj yeem ua rau muaj kev phom sij loj, raws li ceramic capacitors feem ntau ua rau muaj kev cuam tshuam rau kev tswj lub voj voog ntawm cov circuits, xws li cov nyiaj them poob haujlwm lossis cov khoom lim.Cov kab ke uas zoo li ruaj khov nyob rau hauv kev cuam tshuam ntawm kev laus ntawm capacitor thaum lub sij hawm sib dhos yuav ua tsis tau zoo nyob rau lub sijhawm, vim tias qhov poob ntawm lub peev xwm vim kev laus cuam tshuam rau lub zog ntawm lub voj voog tswj.Qhov tseem ceeb tshaj plaws, yog tias qhov muaj peev xwm ruaj khov nyob rau lub sijhawm tseem ceeb, tsis txhob siv cov capacitors uas muaj hnub nyoog pom.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, peb nyob rau hauv ib tug zoo txoj hauj lwm tsis tsuas yog muab koj zoo pnp tshuab, tab sis kuj zoo heev tom qab muag kev pab cuam.Cov kws tshaj lij engineers tau kawm zoo yuav muab kev txhawb nqa rau koj.
10 engineers muaj zog pab neeg tom qab kev muag khoom tuaj yeem teb cov lus nug thiab cov lus nug hauv 8 teev.
Cov kev daws teeb meem muaj peev xwm muab tau hauv 24 teev ob hnub ua haujlwm thiab hnub so.
