Ama-capacitor wefilimu, owaziwa nangokuthi ama-plastic film capacitors, sebenzisa ifilimu yepulasitiki njenge-dielectric, foil yensimbi noma ifilimu eyenziwe ngensimbi njengama-electrode.Izinto ezivame kakhulu ze-dielectric zama-capacitor amafilimu amafilimu e-polyester namafilimu e-polypropylene.
Ama-electrolytic capacitors asebenzisa i-metal foil njenge-electrode eqondile, ifilimu ye-oxide eseduze nensimbi ene-electrode eqondile i-dielectric, kanti i-cathode yakhiwe ngezinto eziqhutshwayo, i-electrolyte (i-electrolyte ingaba uketshezi noma eqinile) nezinye izinto.Ngenxa yokuthi i-electrolyte iyingxenye eyinhloko ye-cathode, ngakho-ke i-electrolytic capacitor yathola igama layo.
Ama-electrolytic capacitors ahlukaniswe abe yizigxobo ezinhle nezimbi, ngakho izigxobo ezinhle nezimbi azikwazi ukuhlehliswa lapho kufakwa ama-electrolytic capacitors, ngaphandle kwalokho kuzodala isifunda esifushane.
Ama-capacitor wefilimu kanye nama-electrolytic capacitors womabili ama-capacitor, uyini umehluko phakathi kwabo?
1. Isikhathi sokuphila: Isikhathi sokusebenza se-electrolytic capacitor sifushane;kuyilapho ama-film capacitors angasebenza isikhathi eside uma nje kungekho nkinga ngekhwalithi, enamandla kunaleyo ye-electrolytic capacitors.
2. Izici zezinga lokushisa: Izinga lokushisa elisebenzayo lama-capacitor wefilimu ngu-40°C~+105°C.Ama-film capacitor anezici ezinhle zokushisa futhi angasebenza ngokujwayelekile ezindaweni ezibandayo noma ezindaweni ezishisayo eziwugwadule;Ngenxa yokuba khona kwe-electrolyte.ama-electrolytic capacitors cishe azoqina endaweni yokushisa ephansi, enciphisa ukusebenza komsebenzi.
3. Izici zokuvama: I-capacitance ye-electrolytic capacitors iyancipha kancane kancane ngokunyuka kwemvamisa, futhi ukulahlekelwa kukhula kakhulu;kuyilapho i-capacitance ye-film capacitors iyancipha kancane kuphela, futhi ama-capacitor wefilimu awanakho ukulahlekelwa okukhulu lapho imvamisa ikhula.Kusukela kuleli phuzu lokusebenza lokubuka ama-capacitor wefilimu anokulahlekelwa okuphansi kanye nezici ezinhle zemvamisa.
I-4.Amandla okumelana no-overvoltage: ama-electrolytic capacitors angakwazi kuphela ukumelana no-overvoltage mayelana ne-20%.Uma i-overvoltage iphakeme, i-electrolytic capacitor izolimala;ama-capacitor efilimu angakwazi ukumelana no-overvoltage ngaphezu kwezikhathi ezingu-1.5 kumthamo olinganiselwe we-voltage ngesikhathi esifushane.
Kusukela ekusebenzeni okungenhla, ukusebenza kwama-capacitor wefilimu kungcono kunama-electrolytic capacitors.Kwezinye izinhlelo zokusebenza, ama-capacitor amafilimu afaneleka kakhulu kunama-electrolytic capacitors.Kodwa-ke, kungakhathaliseki ukuthi ama-capacitors efilimu noma ama-electrolytic capacitors, kuyadingeka ukukhetha ama-capacitor anekhwalithi eqinisekisiwe.
Khetha umkhiqizi onokwethenjelwa lapho uthenga ama-capacitor e-ceramic angagwema izinkinga eziningi ezingadingekile.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.
