Ama-capacitor wefilimuama-capacitor amahle kakhulu ngenxa yezakhiwo zawo eziningi ezinhle kakhulu.Inokumelana nokwehlukanisa okuphezulu, izici ezinhle kakhulu zemvamisa (impendulo yefrikhwensi ebanzi), nokulahleka kwe-dielectric okuphansi.Ngokusekelwe ezinzuzweni ezingenhla, ama-capacitor amafilimu asetshenziswa kabanzi kumasekethe e-analog.Ama-capacitor amafilimu anomsebenzi wokuhlunga, ngakho-ke yini ama-capacitor amafilimu okuhlunga?
I-film capacitor iwuhlobo lwedivayisi yokugcina amandla efakwe kuzo zombili iziphetho zesekhethi yokulungisa kabusha ukuze kwehliswe i-coefficient ye-AC pulsation ripple futhi kuthuthukiswe ukuphuma kwe-DC okubushelelezi.Isifunda sokuhlunga sidinga umthamo omkhulu we-capacitor yokugcina amandla.Kuzo zonke izifunda ezidinga ukuguqula i-alternating current ibe yamanje eqondile, ukusetha ama-capacitor wefilimu yesihlungi kuzokwenza ukusebenza kwesekethe ye-elekthronikhi kuzinze, futhi kunciphise nokuphazanyiswa kwe-ripple eshintshanayo kusekethe kagesi.Kutholakala ukuthi isihlungi sefilimu capacitor siyehluleka ngesikhathi sokusetshenziswa, okungenzeka kube ngenxa yalezi zizathu:
I-1) Ikhwalithi yomkhiqizo we-capacitor yefilimu yokuhlunga ngokwayo, njengenqubo yokukhiqiza engafanelekile kanye nezinto zokwakha, i-capacitance ephawulwe ayihambisani namandla angempela, futhi ukuguga okubangelwa ukusetshenziswa isikhathi eside kuzodala ukutubeka.
2) Ithonya lendawo yangaphandle, njengokufakwa endaweni enokushabalaliswa kahle kokushisa noma eduze nomthombo wokushisa, ukuxhumeka okungalungile kwama-capacitor, ukuthintana kabi, njll., nakho kungabangela ukutubeka kalula.
I-3) Inkinga ye-Harmonic, i-harmonics yenza i-capacitor yefilimu yokuhlunga iphendule, ibangele i-capacitor idlule futhi ishise.
Kunezinye izizathu ezikhethekile.Kudingekile ukuhlaziya nokwahlulela isayithi lapho i-capacitor yefilimu yokuhlunga ishiswa khona, futhi kancane kancane uphenye imbangela yokwehluleka.Ngezinye izikhathi imininingwane emincane ingase ibe imbangela yokutubeka.
Lapho ukhetha i-capacitor yefilimu, udinga ukuthola umenzi onokwethenjelwa.I-JYH HSU (noma i-Dongguan Zhixu Electronics) ayinawo kuphela amamodeli agcwele ama-capacitor e-ceramic anekhwalithi eqinisekisiwe, kodwa futhi inikeza ngaphandle kokukhathazeka ngemva kokuthengisa.Amafekthri e-JEC aphumelele i-ISO9001: isitifiketi sohlelo lokuphathwa kwekhwalithi ka-2015;Ama-capacitor okuphepha e-JEC (ama-X capacitors kanye nama-Y capacitors) kanye nama-varistors aphumelele isitifiketi samazwe ahlukahlukene;Ama-ceramic capacitor e-JEC, ama-filimi capacitor nama-super capacitor ahambisana nezinkomba zekhabhoni ephansi.Siyakwamukela ukuxhumana nathi.
