Txoj Cai Kev Ua Haujlwm ntawm Loj Electrolytic Capacitor

Loj electrolytic capacitors (feem ntau yog xa mus rau txhuas electrolytic capacitors los yog tantalum electrolytic capacitors) yog polarized capacitors nrog cov yam ntxwv ntawm cov capacitance loj, me me, thiab tus nqi qis, dav siv hauv kev lim fais fab, lub zog cia, teeb liab coupling, thiab lwm yam kev siv.

Cov qauv tsim
Anode: High-purity aluminium foil lossis tantalum hlau ntawv, nrog rau qhov chaw electrochemically etched kom nce qhov chaw.

Dielectric: Ib txheej txheej ultra- nyias insulating oxide (xws li Al₂O₃ lossis Ta₂O₅) tsim rau ntawm qhov chaw anode, nrog tuab tsuas yog nyob rau theem nanometer.

Cathode: kua los yog khoom electrolyte (xws li ethylene glycol + boric acid tov los yog MnO₂), muab txoj kev ionic conductive.

Casing: kaw lub plhaub hlau nrog lub qhov cua sab saum toj kom tso tawm cov pa hauv lub siab.

Kev them nyiaj yug
Cov hluav taws xob siv hluav taws xob rub cov hluav taws xob los ntawm lub anode mus rau qhov zoo kawg nkaus ntawm lub zog hluav taws xob.

Cations nyob rau hauv cov electrolyte txav mus rau cathode, thaum anions txav los ze zog rau lub anode.

Ib qho hluav taws xob muaj zog ua rau ntawm anode / dielectric interface, khaws cia nqi.

Cov txheej txheem oxide muaj tus kheej- kho muaj peev xwm: Nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj hauv zos, electrolyte ions tuaj yeem rov tsim cov oxide zaj duab xis los kho cov rwb thaiv tsev.

Cov txheej txheem tshem tawm
Thaum txuas nrog ib qho load, lub zog hluav taws xob tsis muaj zog, ions redistribute, thiab cov hluav taws xob tso tawm lub zog los ntawm sab nraud Circuit Court, ua tiav cov khoom siv hluav taws xob sai.
