Kuma-capacitor efilimu enziwe ngensimbi, ifilimu yensimbi inamathiselwe ebusweni befilimu ye-polyester kusetshenziswa indlela yokubeka umhwamuko.Ngakho-ke, ifilimu yensimbi iba i-electrode esikhundleni sensimbi yensimbi.Ngenxa yokuthi ubukhulu bongqimba lwefilimu eyenziwe ngensimbi buncane kakhulu kunobucwecwe bensimbi, ivolumu ngemva kokusonteka nayo incane kunaleyo ye-capacitor ye-foil yensimbi.Eminyakeni yamuva, ama-capacitor amafilimu ensimbi aye athandwa ngoba lolu hlobo lwe-capacitor lusebenza kahle kakhulu.Kulesi sihloko sizokhuluma ngezinzuzo kanye nokubi kwe-capacitors yefilimu yensimbi.
Isici "sokuziphilisa" siyinzuzo ebaluleke kakhulu yama-capacitor amafilimu ensimbi.Isici esibizwa ngokuthi ukuziphulukisa ukuthi uma i-dielectric yefilimu encane ineziphambeko endaweni ethile, i-breakdown short-circuit izokwenzeka ngaphansi kwesenzo se-overvoltage.Isendlalelo se-metalization endaweni yokuqhekeka singancibilika futhi sihwamuke ngokushesha ngaphansi kwesenzo se-arc ukuze senze indawo encane engenazo insimbi, ukuze izingcezu ezimbili zezigxobo ze-capacitor ziphinde zihlanganiswe komunye nomunye futhi ziqhubeke nokusebenza, okuzokwenza ngcono kakhulu ukuthembeka kwe-capacitor.
Ububi bama-capacitor efilimu enziwe ngensimbi yikhono lawo elimpofu lokumelana namaza amakhulu.Lokhu kungenxa yokuthi ungqimba lwefilimu ene-metalized luncane kakhulu kune-foil yensimbi, futhi amandla okuthwala imisinga emikhulu abuthakathaka.Ukuze kuthuthukiswe ukushiyeka kwama-capacitor amafilimu enziwe ngensimbi, okwamanje kunemikhiqizo ethuthukisiwe yamanje ye-metallised film capacitor enqubweni yokukhiqiza.Izindlela eziyinhloko zokuthuthukisa yilezi: sebenzisa amafilimu anezinhlangothi ezimbili zensimbi njengama-electrode;ukwandisa ukushuba kwe-metalized coating;ngcono inqubo yokushisela insimbi ukuze kuncishiswe ukumelana nokuxhumana.
Okuqukethwe okungenhla kuyizinzuzo kanye nokubi kwama-capacitor amafilimu ensimbi.Ama-capacitor amafilimu amahle anensimbi anganciphisa izinkinga ezingadingekile.I-JYH HSU(JEC) Electronics Ltd (noma i-Dongguan Zhixu Electronic Co., Ltd.) ibambe iqhaza embonini yezingxenye zikagesi iminyaka eminingi, futhi onjiniyela bethu bezobuchwepheshe bangakusiza ukuxazulula izinkinga ezihlobene.Lapho uthenga ama-varistors, udinga ukuthola ukuthi imikhiqizo ivela kubakhiqizi abajwayelekile.Umkhiqizi omuhle we-varistor anganciphisa izinkinga eziningi ezingadingekile.
I-JEC ineminyaka engaphezu kwengama-30 yesipiliyoni sokukhiqiza embonini yezingxenye ze-elekthronikhi.Uma unemibuzo yobuchwepheshe noma udinga amasampula, sicela usithinte.
