Uma kukhulunywa ngokukhetha uhlobo olufanele lwe-capacitor ukuthola uhlelo lwe-elekthronikhi, izinqumo zivame ukuba yize. Enye yezinhlobo ezivame kakhulu ama-capacitors ezisetshenziswa kwimibuthano ye-elekthronikhi yi-electrolytic capacitor. Ngaphakathi kwalesi sigaba, kunama-subtypes amabili amakhulu: ama-capacitors we-aluminium electrolytic nama-polymer electrolytic ama-electrolytic. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-capacitors kubalulekile ekukhetheni i-capacitor efanelekile yesicelo esithile.
I-Aluminium electrolytic capacitorsUhlobo lwendabuko futhi olusetshenziswa kabanzi lwama-capacitors we-electrolytic. Bayaziwa ngenani labo eliphakeme lamakhono kanye nekhono lokuphatha amazinga aphezulu kagesi. Lawa ma-capacitors enziwe asebenzisa iphepha elifakwe nge-electrolyte njenge-dielectric ne-aluminium foil njenge-electrodes. I-electrolyte imvamisa iwuketshezi noma i-gel into, futhi kungukusebenzisana phakathi kwe-electrolyte kanye ne-aluminium foil evumela ukuthi ama-capacitor avumele futhi akhiphe amandla kagesi.
Ama-capacitors e-polymer electrolytic, ngakolunye uhlangothi, uhlobo olusha, oluthuthukile kakhulu lwe-electrolytic capacitor. Esikhundleni sokusebenzisa i-ketshezi noma i-gel electrolyte, ama-polymer capacitors asebenzisa i-polymer eqinile ye-elecymer njenge-electrolyte, okuholela ekuzinyokeni okungcono nokumelana kwangaphakathi okuphansi. Ukusetshenziswa kobuchwepheshe boMbuso oqinile kuma-polymer capacitors kungakhuphula ukuthembeka, ukunweba impilo yensiza, futhi kunikeze ukusebenza okungcono ekufinyelelekelweni okuphezulu kanye nezicelo zokushisa okuphezulu.
Omunye umehluko omkhulu phakathiI-Aluminium electrolytic capacitorskanye nama-polymer electrolytic capacitors yimpilo yabo yenkonzo. Ama-capacitors we-Aluminium Electrolytic ngokuvamile anempilo emfushane kune-polymer capacitors futhi athambekele ekwehluleka ukwehluleka ngenxa yezinto eziphakeme njengokushisa okuphezulu, ukucindezelwa kwe-voltage, kanye ne-ripple yamanje. Ngakolunye uhlangothi, ama-capacitors e-polymer, anempilo yenkonzo ende futhi yakhelwe ukumelana nezimo zokusebenza kwe-harsher, ezenza zilungele ukusetshenziswa ezinhlelweni ezifunwayo.
Omunye umehluko obalulekile yi-ESR (ukumelana kochungechunge okulinganayo) kwama-capacitors amabili. Ama-capacitors we-aleminium electrolytic ane-ESR ephakeme ngokuqhathaniswa nama-polymer capacitors. Lokhu kusho ukuthi ama-capacitors we-polymer anokumelana okuphansi kwangaphakathi, okuphumela ekusebenzeni okungcono ngokuya nge-rippple yamanje, isizukulwane sokushisa kanye nokuhlakazeka kwamandla.
Ngokuya ngosayizi nesisindo, ama-capacitors e-polymer ngokuvamile ancanyana futhi alula kunama-aluminium capacitors okukhokhwa kwamandla okufanayo nokukalwa kwamandla. Lokhu kubenza balungele kakhulu amadivaysi acwebile futhi angasindi ama-elekthronikhi, lapho isikhala nesisindo ukucatshangelwa okubalulekile.
Ngamafuphi, kanti ama-capacitors we-Aluminium Electrolytic abebekhethile iminyaka eminingi ngenxa yamanani awo aphezulu aphezulu ngenxa yamanani awo aphezulu ama-capcacitance kanye nezilinganiso ze-volmer electrolytic, ama-polymer electrolytic capacitors anikela ngezinzuzo eziningana ngokwesikhathi eside, ukusebenza, nosayizi. Ukukhetha phakathi kwezinhlobo ezimbili zama-capacitors kuya ngezidingo ezithile zohlelo lokusebenza, njengezimo zokusebenza, izingqinamba zesikhala, nezidingo zokusebenza.
Sonke, ama-capacitors we-electrolytic angu-Aluminium angu-Aluminium kanye nama-polymer electrolytic anezinzuzo zawo kanye nobunzima. Ukuze ukhethe uhlobo olufanele kakhulu lwe-capacitor ukuthola uhlelo lokusebenza, kubalulekile ukubheka ngokucophelela izidingo ezithile kanye nezimo zokusebenza zomjikelezo we-elekthronikhi. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, ama-polymer electrolytic capacitors aya ngokuya ethandwa ngenxa yokusebenza kwawo okuthuthukile kanye nokwethenjwa, abenze enye indlela efanelekile kuma-capacitors we-aluminium electronic ezintweni eziningi ze-elekthronikhi.
