Tare da haɓakar kimiyya da fasaha, samfuran lantarki sun zama wani abu da ba dole ba ne a cikin rayuwar yau da kullun na mutane.Kayayyakin lantarki suna sanye da kayan aikin lantarki daban-daban, kamar yumbu capacitors.
1. Menene capacitor yumbu?
Ceramic capacitor ( yumbu condenser) yana amfani da high dielectric akai yumbu a matsayin dielectric, fesa azurfa Layer a bangarorin biyu na yumbu substrate, sa'an nan da azurfa fim da aka gasa a high zafin jiki kamar yadda electrode, gubar waya welded a kan lantarki, da kuma an lulluɓe saman da enamel na kariya ko an rufe shi da resin epoxy.Siffar sa galibi a sigar takarda ce, amma kuma tana da siffar bututu, da'ira da sauran siffofi.
Ƙwararrun yumbura da aka yi amfani da su a filin lantarki suna da fa'idodin ƙananan girman, ƙarfin juriya, da kuma mitar mai kyau.Tare da ci gaba da ci gaban kimiyya da fasaha, yumbu capacitors sun zama wani abu mai mahimmanci na lantarki don samfuran lantarki.
2. Me yasa yumbu capacitors "kururuwa"?
Lokacin amfani da samfuran lantarki, wani lokacin za ku ji hayaniya.Ko da yake sautin ƙarami ne, har yanzu za ku iya ji idan kun saurara da kyau.menene wannan sautin?Me yasa wannan sauti yayin amfani da samfuran lantarki?
A gaskiya ma, wannan sauti yana faruwa ta hanyar yumbura capacitors.Saboda babban dielectric akai-akai na yumbu capacitors, kayan yana samar da haɓaka mai ƙarfi da lalacewa a ƙarƙashin aikin filin lantarki na waje, wanda ake kira tasirin piezoelectric.Faɗawar tashin hankali da ƙullawa yana sa saman allon kewayawa ya yi rawar jiki da fitar da sauti.Lokacin da mitar girgiza ta faɗi tsakanin kewayon ji na ɗan adam (20Hz ~ 20Khz), za a haifar da hayaniya, wanda shine abin da ake kira "hakan".
Ko kwamfutar tafi-da-gidanka ce ko wayar hannu, abubuwan da ake buƙata don samar da wutar lantarki suna ƙaruwa, don haka babban adadin capacitors na MLCC ana haɗa su a layi daya akan hanyar sadarwar samar da wutar lantarki, kuma yana da sauƙin yin bushewa lokacin da ƙirar ba ta da kyau. ko yanayin aiki na kaya ba daidai ba ne.
Abubuwan da ke sama shine dalilin da yasa yumbu capacitors "kuri".
Zaɓi wani abin dogara lokacin da siyan yumbu capacitors zai iya guje wa matsala mai yawa mara amfani.Maƙerin asali na JEC ba wai kawai yana da cikakkun samfuran yumbu capacitors tare da ingantacciyar inganci ba, har ma yana ba da kyauta bayan tallace-tallace.JEC masana'antu sun wuce ISO9001: 2015 ingancin tsarin gudanarwa;JEC aminci capacitors (X capacitors da Y capacitors) da varistors sun wuce takaddun shaida na ƙasashe daban-daban;JEC yumbu capacitors, fim capacitors da super capacitors suna cikin layi tare da ƙananan alamun carbon.
