Thaum nws los xaiv hom capos lub caposit rau daim ntawv thov hluav taws xob, cov kev xaiv feem ntau tuaj yeem ua npau taws. Ib qho ntawm feem ntau hom capacitors siv nyob rau hauv cov hluav taws xob hluav taws xob yog cov khoom siv hluav taws xob electrolytic. Tsis pub dhau Pawg no, muaj ob lub ntsiab subtypes: Altrolytic capacitors thiab polymer electrolytic capacitors. Nkag siab txog qhov sib txawv ntawm ob hom kev siv hluav taws no yog qhov tseem ceeb rau xaiv tus capacitor raug rau ib daim ntawv thov raug cai.
Aluminium Electrolytic Capacitorsyog cov ib txwm muaj thiab dav hom electrolytic capacitors. Lawv paub rau lawv lub peev xwm siab muaj nuj nqis thiab muaj peev xwm los daws cov hluav taws xob voltage ntau. Cov capacitors tau tsim kev siv ntawv impregnated nrog electrolyte raws li dielectric thiab txhuas ntawv ci ua cov electrodes. Cov electrolyte feem ntau yog kua lossis khoom siv gel, thiab nws yog kev sib cuam tshuam ntawm cov electrolyte thiab tso cov capacitors khaws thiab tso lub zog hluav taws xob.
Polymer electrolytic capacitors, ntawm qhov tod tes, yog ib qho tshiab, ntau dua hom electrolytic capacitor. Hloov chaw siv kua lossis gel electrolyte, polymer capacitors siv cov khoom siv polymer uas yog cov electrolyte, ua rau muaj kev ruaj khov zoo dua thiab qis dua sab hauv kev tsis kam thiab qis dua. Kev siv cov cuab yeej-lub xeev thev naus laus zis nyob rau hauv kev ntseeg siab, txuas ntxiv lub neej pabcuam thiab muaj kev ua haujlwm zoo dua qub.
Ib qho ntawm qhov sib txawv tseem ceeb ntawmAluminium Electrolytic Capacitorsthiab polymer electrolytic capacitors yog lawv lub neej kev pabcuam. Aluminium electrolytic capacitors feem ntau muaj lub neej luv dua polymer capacitors thiab ntau dua qhov kub thiab txias, thiab cov rippage tam sim no. Polymer capacitors, ntawm qhov tod tes, muaj lub neej muaj kev pab cuam ntev dua thiab tsim los tiv thaiv hnyav ua haujlwm.
Lwm qhov sib txawv tseem ceeb yog ESR (sib npaug series tiv taus) ntawm ob qho capacitors. Aluminium electrolytic capacitors muaj ntau dua ESR piv rau polymer capacitors. Qhov no txhais tau tias cov polymer capacitors muaj qis dua kev tawm tsam, ua rau muaj kev ua tau zoo dua qub ntawm Ripple tam sim no, cua sov tiam thiab lub zog tsis txaus ntseeg.
Nyob rau hauv cov nqe lus ntawm qhov loj thiab qhov hnyav, polymer capacitors feem ntau me dua thiab sib zog dua li txhuas capinance thiab voltage ntsuas. Qhov no ua rau lawv haum ntau rau kev cog lus thiab teeb hluav taws xob hauv tshuab hluav taws xob, qhov chaw thiab qhov hnyav yog qhov kev txiav txim siab tseem ceeb.
Hauv cov ntsiab lus xaus, thaum txhuas electrolytic capacitors tau xaiv ntau xyoo vim lawv cov txiaj ntsig kev ntsuas hluav taws xob muaj ntau lub zog muaj ntau cov txiaj ntsig zoo, kev ua tau zoo, thiab qhov loj me. Xaiv ntawm ob hom capacitors nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov, xws li ua haujlwm, chaw muaj kev txwv, thiab kev ua tau zoo.
Tag nrho cov hauv txhua qhov, ob qho tib si txhuas electrolytic capacitors thiab polymer electrolytic capacitors muaj lawv tus kheej thiab qhov tsis zoo. Txhawm rau xaiv cov capinctor hom rau daim ntawv thov, nws yog ib qho tseem ceeb kom ua tib zoo xav txog qhov ua tau zoo thiab kev ua haujlwm ntawm hluav taws xob hluav taws xob. Raws li thev naus laus zis tseem ua ntej, polymer electrolytic capacitors tau ua kom nrov dua vim lawv txoj kev txhim kho kom zoo nkauj hauv ntau cov ntawv thov hluav taws xob.
