Ii-capacitors zefilimuzi-capacitors ezigqwesileyo ngenxa yeepropathi zazo ezininzi ezigqwesileyo.Inokumelana ne-insulation ephezulu, iimpawu ezibalaseleyo zefrikhwensi (impendulo yefrikhwensi ebanzi), kunye nelahleko ephantsi ye-dielectric.Ngokusekelwe kwiinzuzo ezingentla, ii-capacitors zefilimu zisetyenziswa ngokubanzi kwiisekethe ze-analog.I-Film capacitors inomsebenzi wokucoca, ngoko ke yintoni i-filtering capacitors?
Isihluzi sefilimu capacitor luhlobo lwesixhobo sokugcina amandla esifakwe kuzo zozibini iziphelo zesekethe yokuhlaziya ukunciphisa i-AC pulsation ripple coefficient kunye nokuphucula ukuphuma kwe-DC egudileyo.Isiphaluka sokucoca sidinga umthamo omkhulu we-capacitor yokugcina amandla.Kuzo zonke iisekethe ezifuna ukuguqula i-alternating current kwi-current ngqo, ukuseta i-filter film capacitors kuya kwenza ukuba ukusebenza kwe-electronic circuit kuzinzile, kwaye kunciphise ukuphazamiseka kwe-alternating ripple kwisekethe ye-elektroniki.Kufunyaniswe ukuba isihluzi sefilimu capacitor asiphumelelanga ngexesha lokusetyenziswa, ekunokwenzeka ukuba kungenxa yezi zizathu:
I-1) Umgangatho wemveliso ye-filter film capacitor ngokwayo, njengenkqubo yokuvelisa engafanelekanga kunye nezinto eziphathekayo, i-capacitance ephawulweyo ayihambelani ne-capacitance yangempela, kwaye ukuguga okubangelwa ukusetyenziswa kwexesha elide kuya kubangela ukutshiswa.
I-2) Impembelelo yendawo yangaphandle, njengokufakwa kwindawo enokutshatyalaliswa kobushushu okanye kufuphi nomthombo wokushisa, uxhulumaniso olubi lwe-capacitors, ukudibanisa kakubi, njl., kunokubangela ukuba kube lula ukutshisa.
I-3) Ingxaki ye-Harmonic, i-harmonics yenza i-filter film capacitor ihlaziye, ibangele ukuba i-capacitor idlule kwaye itshise.
Kukho ezinye izizathu ezikhethekileyo.Kuyimfuneko ukuhlalutya kunye nokugweba indawo apho i-capacitor yefilimu yokucoca itshiswa, kwaye ngokuthe ngcembe iphande isizathu sokungaphumeleli.Ngamanye amaxesha iinkcukacha ezincinci zinokuba yimbangela yokudinwa.
Xa ukhetha i-capacitor yefilimu, kufuneka ufumane umenzi othembekileyo.I-JYH HSU (okanye i-Dongguan Zhixu Electronics) ayinayo kuphela imifuziselo epheleleyo yeecapacitor ze-ceramic ezinomgangatho oqinisekisiweyo, kodwa inikezela ngokungenaxhala emva kokuthengisa.Iifektri zeJEC ziphumelele i-ISO9001: isiqinisekiso senkqubo yolawulo lwe-2015;I-JEC i-capacitors yokhuseleko (i-X capacitors kunye ne-Y capacitors) kunye ne-varistors ziye zadlula isatifikethi samazwe ahlukeneyo;I-JEC i-ceramic capacitors, i-filimi capacitors kunye ne-super capacitors ihambelana nezalathi zekhabhoni ephantsi.Wamkelekile ukuba uqhagamshelane nathi.
