Specification

Cov yam ntxwv ua tau zoo ntawm cov yeeb yaj kiab capacitors sib txawv feem ntau nyob ntawm cov khoom siv dielectric siv nrog rau kev siv tshuab siv.Qee qhov feem ntau siv cov yas zaj duab xis dielectrics suav nrog polyethylene naphthalate (PEN), polyethylene terephthalate (PET), thiab polypropylene (PP).

Yas zaj duab xis capacitors tuaj yeem faib dav rau hauv zaj duab xis / ntawv ci thiab metallized zaj duab xis capacitors.Lub hauv paus qauv ntawm ib zaj duab xis / ntawv ci capacitor muaj ob hlau ntawv ci electrodes thiab ib tug yas zaj duab xis dielectric ntawm lawv.Zaj duab xis / ntawv ci capacitors muaj kev rwb thaiv tsev siab, siab mem tes tuav, muaj peev xwm nqa tau zoo tam sim no, thiab kev ruaj ntseg zoo.Tsis zoo li zaj duab xis / ntawv ci capacitors, metallized zaj duab xis capacitors siv hlau-coated yas zaj duab xis ua electrodes.Metallized zaj duab xis capacitors tau txo qhov loj ntawm lub cev, thiab muaj kev ua haujlwm siab volumetric, zoo capacitance stability, tsis tshua muaj dielectric poob, thiab zoo heev rau nws tus kheej zoo.Qee cov capacitors yog ib qho hybrid ntawm zaj duab xis / ntawv ci capacitors thiab metallized zaj duab xis capacitors thiab cov yam ntxwv ntawm ob hom.Cov khoom kho tus kheej ntawm metallized zaj duab xis capacitors ua rau lawv zoo tagnrho rau kev siv dav dav, suav nrog lub neej ntev thiab benign tsis ua haujlwm hom circuits.

Self-kho ntawm metallized zaj duab xis capacitors

Cov yas zaj duab xis dielectrics uas feem ntau yog siv rau hauv kev tsim kho ntawm metallized film capacitors muaj xws li polypropylene (PP), polyphenylene sulfide (PPS), polyester, thiab metalized paper (MP).Cov khoom siv dielectric no muaj peev xwm kho tus kheej sib txawv.

Thaum tawg tshwm sim nyob rau hauv lub metallized zaj duab xis capacitor, arcing ua rau nyias hlau txheej nyob ib ncig ntawm qhov chaw txhaum mus vaporize.Cov txheej txheem vaporization no tshem tawm cov txheej txheem hlau conductive hauv cheeb tsam ib puag ncig qhov tsis zoo.Txij li thaum cov khoom siv hluav taws xob raug tshem tawm, qhov luv luv tsis tuaj yeem tshwm sim ntawm daim hlau.Qhov no tiv thaiv tsis ua hauj lwm ntawm cov khoom.

Lub peev xwm kho tus kheej ntawm lub tshuab hluav taws xob metallized yog nyob ntawm ntau yam nrog rau cov khoom ntawm cov khoom siv dielectric thiab cov thickness ntawm cov hlau txheej.Cov txheej txheem vaporization yuav tsum muaj cov pa oxygen txaus thiab cov khoom siv dielectric nrog cov ntsiab lus siab ntawm cov pa oxygen muaj qhov zoo ntawm tus kheej.Qee cov yas zaj duab xis dielectrics uas muaj cov yam ntxwv zoo ntawm tus kheej zoo xws li polypropylene, polyester thiab polycarbonate.Ntawm qhov tod tes, yas zaj duab xis dielectrics nrog cov ntsiab lus ntawm cov pa oxygen tsawg muaj cov yam ntxwv kho tus kheej tsis zoo.Polyphenylene sulfide (PPS) yog ib qho khoom siv dielectric.

Sib nrug los ntawm kev txhim kho kev ntseeg siab, kev kho tus kheej muaj peev xwm ntawm metallized film capacitors pab txhim kho lawv lub neej ua haujlwm.Txawm li cas los xij, kev kho tus kheej ua rau txo qis ntawm thaj chaw metallized electrode nyob rau lub sijhawm.

Hauv cov ntawv thov, qee qhov xwm txheej uas tuaj yeem ua kom tsis ua haujlwm ntawm cov khoom muaj xws li kub siab, siab voltages, xob laim, siab av noo, thiab electromagnetic cuam tshuam (EMI).

Sib nrug los ntawm kev kho tus kheej zoo, metallized polyester zaj duab xis capacitors kuj muaj lub siab dielectric tas li, zoo kub stability, siab dielectric zog, thiab zoo heev volumetric efficiency.Cov yam ntxwv no ua rau cov capacitors zoo tagnrho rau kev siv dav dav.Metallized polyester capacitors yog dav siv rau DC daim ntaub ntawv xws li thaiv, bypassing, decoupling, thiab suab nrov.

Metallized polypropylene capacitors muaj kev rwb thaiv tsev siab, tsis tshua muaj dielectric absorption, tsis tshua muaj dielectric poob, siab dielectric zog, thiab lub sij hawm ntev stability.Cov khoom siv hluav taws xob zoo no tau siv dav hauv cov ntawv thov tseem ceeb xws li lim circuits, teeb pom kev zoo ballasts, thiab snubber circuits.Ob chav metallized polypropylene zaj duab xis capacitors tuaj yeem tiv taus siab voltage thiab siab-pulse loads, thiab lawv tsim nyog rau cov ntawv thov uas muaj feem ntau ntawm cov pulses siab.Cov capacitors no feem ntau siv rau hauv cov tswj lub cev muaj zog, snubbers, hloov hom fais fab mov, thiab saib xyuas.

Xaus

Kev ntseeg siab thiab kev ua haujlwm lub neej ntawm capacitors tseem nyob ntawm lawv tus kheej cov yam ntxwv kho.Passive Cheebtsam nrog cov yam ntxwv zoo ntawm tus kheej zoo yog txhim khu kev qha thiab muab lub neej ua haujlwm ntev dua.Cov yam ntxwv zoo ntawm tus kheej zoo ntawm metallized zaj duab xis capacitors txhim kho lawv cov robustness thiab ua rau lawv haum rau ntau daim ntawv thov.Tsis tas li ntawd, cov khoom muaj zog no tsis qhib-circuit, thiab qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau cov khoom siv nrog kev nyab xeeb tsis ua haujlwm.

Nyob rau sab ntxeev, cov cuab yeej kho tus kheej ntawm metallized zaj duab xis capacitors ua rau qhov poob qhov nce ntxiv thiab tag nrho cov capacitance poob.Sib nrug los ntawm kev kho tus kheej zoo, feem ntau metallized zaj duab xis capacitors kuj muaj lub zog tawg siab thiab ua haujlwm siab volumetric.
