Ama-filimi capacitor anokumelana nokushisa okuphezulu nokumelana nokushisa okuhle.Inezinto zokuziphilisa kanye ne-high-frequency insulation properties, kodwa njengenye yezingxenye ze-elekthronikhi, ama-capacitor wefilimu nawo angalimala.
Lapho ama-capacitor wefilimu evezwa ekushiseni okuphezulu kanye nemvelo yomswakama ophezulu isikhathi eside, i-capacitor kulula ukuhluleka.Isizathu esiyinhloko sokulimala kwama-capacitor wefilimu ukuthi ama-molecule anamandla okusabalalisa okunamandla, futhi i-dielectric constant yamanzi inkulu, futhi ukulahlekelwa nakho kukhulu, okuholela ekuwohlokeni okubukhali kwezakhiwo zikagesi ze-capacitor, njenge. ukwehla kokumelana nokufakwa kwe-insulation kanye nokumelana ne-voltage, kanye ne-dielectric loss angle.I-Tangent iyanda kanye noshintsho lwamandla.Ikakhulukazi lapho izinga lokushisa lendawo likhuphuka, amandla okusabalalisa ama-molecule amanzi ayanda.Ngakho-ke, izinga lokushisa eliphezulu kanye nemvelo yomswakama ophezulu (efana no-85 ° C, 85% RH) inomthelela omkhulu ezicini zikagesi ze-capacitor, okuholela ekwenyukeni kwezinga lokuhluleka komkhiqizo, kunciphisa ukwethembeka nokulimala kwe-film capacitor.
Ngaphezu kwalokho, ukulahlekelwa kwama-capacitor amafilimu kuhlobene nenqubo yokukhiqiza.Uma inqubo yokukhiqiza ingalawuleki ngokuqinile, kuzoba nezinkinga ezifana ne-dielectric, ukulimala kwemishini, izimbobo, kanye nokuhlanzeka okuphansi.Ngakho-ke, kubaluleke kakhulu kithi ukukhetha umenzi we-capacitor wefilimu onekhwalithi eqinisekisiwe.Ukuze ugweme ukuthenga ama-filimi capacitor akhiqizwa ama-workshop amancane, qiniseka ukuthi uyakuqonda ulwazi lomkhiqizi ngaphambi kokuthenga.
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.
