Thaum nws los txog rau kev xaiv qhov zoo ntawm capacitor rau daim ntawv thov hluav taws xob, cov kev xaiv feem ntau tuaj yeem kiv taub hau. Ib qho ntawm feem ntau hom capacitor siv hauv hluav taws xob circuits yog electrolytic capacitor. Nyob rau hauv pawg no, muaj ob lub ntsiab subtypes: txhuas electrolytic capacitors thiab polymer electrolytic capacitors. Nkag siab qhov sib txawv ntawm ob hom capacitor yog qhov tseem ceeb rau kev xaiv lub capacitor kom raug rau ib daim ntawv thov tshwj xeeb.
Aluminium electrolytic capacitoryog cov tsoos ntau dua thiab dav siv hom electrolytic capacitors. Lawv paub txog lawv tus nqi siab capacitance thiab muaj peev xwm los tswj cov qib high voltage. Cov capacitors no yog tsim los siv daim ntawv impregnated nrog electrolyte li dielectric thiab aluminium ntawv ci raws li cov electrodes. Cov electrolyte feem ntau yog cov kua los yog gel, thiab nws yog kev sib cuam tshuam ntawm cov electrolyte thiab aluminium foil uas tso cai rau cov capacitors khaws cia thiab tso tawm hluav taws xob.
Polymer electrolytic capacitor, ntawm qhov tod tes, yog ib qho tshiab, ntau dua hom electrolytic capacitor. Es tsis txhob siv cov kua los yog gel electrolyte, cov khoom siv hluav taws xob polymer siv cov khoom siv hluav taws xob zoo li cov electrolyte, uas ua rau muaj kev ruaj ntseg zoo dua thiab qis dua sab hauv. Kev siv cov thev naus laus zis hauv lub xeev hauv cov khoom siv polymer tuaj yeem ua rau muaj kev ntseeg siab, txuas ntxiv lub neej kev pab cuam, thiab muab kev ua tau zoo dua hauv kev siv high-frequency thiab high-temperature.
Ib qho ntawm qhov sib txawv tseem ceeb ntawmaluminium electrolytic capacitorthiab polymer electrolytic capacitors yog lawv lub neej kev pab cuam. Aluminium electrolytic capacitors feem ntau muaj lub neej luv dua li polymer capacitors thiab muaj kev cuam tshuam ntau dua rau kev ua tsis tiav vim muaj cov yam ntxwv xws li kub siab, voltage, thiab ripple tam sim no. Polymer capacitors, ntawm qhov tod tes, muaj lub neej ua haujlwm ntev dua thiab tsim los tiv thaiv kev ua haujlwm hnyav, ua rau lawv tsim nyog rau kev siv hauv kev thov.
Lwm qhov sib txawv tseem ceeb yog ESR (sib npaug series tsis kam) ntawm ob lub capacitors. Aluminium electrolytic capacitor muaj ESR siab dua piv rau cov khoom siv polymer. Qhov no txhais tau hais tias polymer capacitors muaj qhov tsis zoo sab hauv, ua rau muaj kev ua tau zoo dua ntawm kev tuav tam sim no, kev tsim hluav taws xob thiab hluav taws xob dissipation.
Hais txog qhov loj thiab qhov hnyav, cov khoom siv polymer feem ntau me dua thiab sib zog dua li txhuas capacitors ntawm cov khoom siv hluav taws xob zoo sib xws thiab qhov ntsuas hluav taws xob. Qhov no ua rau lawv tsim nyog rau cov khoom siv hluav taws xob compact thiab lub teeb yuag, qhov chaw thiab qhov hnyav yog qhov tseem ceeb rau kev txiav txim siab.
Hauv cov ntsiab lus, thaum txhuas electrolytic capacitors yog qhov kev xaiv zoo tshaj plaws rau ntau xyoo vim lawv cov peev txheej siab thiab qhov ntsuas hluav taws xob, polymer electrolytic capacitors muaj ntau qhov zoo ntawm kev ua haujlwm ntev, kev ua haujlwm, thiab qhov loj me. Kev xaiv ntawm ob hom capacitors nyob ntawm qhov kev xav tau tshwj xeeb ntawm daim ntawv thov, xws li kev ua haujlwm, kev txwv qhov chaw, thiab kev ua haujlwm.
Txhua yam, ob qho tib si txhuas electrolytic capacitors thiab polymer electrolytic capacitors muaj lawv tus kheej zoo thiab qhov tsis zoo. Txhawm rau xaiv hom capacitor uas tsim nyog tshaj plaws rau daim ntawv thov, nws yog ib qho tseem ceeb kom ua tib zoo xav txog cov kev cai tshwj xeeb thiab kev ua haujlwm ntawm cov hluav taws xob hluav taws xob. Raws li thev naus laus zis txuas ntxiv mus, polymer electrolytic capacitors tau dhau los ua neeg nyiam vim lawv cov kev ua tau zoo thiab kev ntseeg tau, ua rau lawv muaj txiaj ntsig zoo rau cov tsoos txhuas electrolytic capacitors hauv ntau daim ntawv thov hluav taws xob.
