Ukuthelekisa iFilimu Capacitors kunye ne-Electrolytic Capacitors

Ii-capacitors zefilimu, eyaziwa ngokuba yi-plastic film capacitors, sebenzisa ifilimu yeplastiki njenge-dielectric, i-foil yensimbi okanye ifilimu enesinyithi njenge-electrode.Izixhobo eziqhelekileyo ze-dielectric ze-film capacitors ziyifilimu ze-polyester kunye neefilimu ze-polypropylene.

I-electrolytic capacitors isebenzisa i-foil yensimbi njenge-electrode efanelekileyo, ifilimu ye-oxide ekufutshane nesinyithi kunye ne-electrode efanelekileyo yi-dielectric, kwaye i-cathode yenziwe ngezinto eziphathekayo, i-electrolyte (i-electrolyte ingaba lulwelo okanye iqinile) kunye nezinye izinto.Ngenxa yokuba i-electrolyte yeyona ndawo iphambili ye-cathode, ngoko ke i-electrolytic capacitor inegama layo.

I-electrolytic capacitors ihlukaniswe kwiipali ezintle kunye nezibi, ngoko ke iipali ezilungileyo kunye nezibi azikwazi ukuguqulwa xa ufaka i-electrolytic capacitors, ngaphandle koko kuya kubangela isiphaluka esifutshane.

I-Film capacitors kunye ne-electrolytic capacitors zombini i-capacitors, yintoni umehluko phakathi kwabo?

1. Ixesha lokuphila: Ixesha lokusebenza kwe-electrolytic capacitors lifutshane;ngelixa i-filimi capacitors ingasebenza ixesha elide ngaphandle kokuba akukho ngxaki kumgangatho, onamandla kunalowo we-electrolytic capacitors.

2. Iimpawu zobushushu: Uluhlu lweqondo lokushisa olusebenzayo lwefilimu capacitors -40 ° C ~ + 105 ° C.I-Film capacitors ineempawu ezintle zokushisa kwaye inokusebenza ngokuqhelekileyo kwiindawo ezibandayo okanye kwiindawo ezishushu zentlango;Ngenxa yobukho be-electrolyte.i-electrolytic capacitors inokuthi iqiniswe kwindawo yokushisa ephantsi, ukunciphisa ukusebenza komsebenzi.

3. Iimpawu zokuphindaphinda: I-capacitance ye-electrolytic capacitors iyancipha ngokuthe ngcembe ngokunyuka kwamaxesha amaninzi, kwaye ilahleko ikhula ngokukhawuleza;ngelixa i-capacitance ye-film capacitors iyancipha kuphela, kwaye i-filimi capacitors ayinayo ilahleko enkulu xa i-frequency inyuka.Ukusuka kule ndawo yokujonga ifilimu i-capacitors inelahleko ephantsi kunye neempawu ezintle zokuphindaphinda.

I-4.Amandla okumelana nokugqithisa: i-electrolytic capacitors inokumelana kuphela nokugqithisa malunga ne-20%.Xa i-overvoltage iphezulu, i-electrolytic capacitors iya konakala;ii-capacitors zefilimu ziyakwazi ukumelana no-overvoltages ngaphezulu kwe-1.5 amaxesha ombane olinganisiweyo ngexesha elifutshane.

Ukususela kwintsebenzo engentla, ukusebenza kweefilimu zefilimu kungcono kune-electrolytic capacitors.Kwezinye izicelo, ii-filimi capacitors zifanelekile ngakumbi kune-electrolytic capacitors.Nangona kunjalo, nokuba ngaba ifilimu i-capacitors okanye i-electrolytic capacitors, kuyimfuneko ukukhetha ii-capacitors ezinomgangatho oqinisekisiweyo.

Khetha umenzi othembekileyo xa uthenga i-ceramic capacitors unokuphepha iingxaki ezininzi ezingeyomfuneko.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.
