Xa kuziwa kwi-electrolytic capacitors, izinto ezikhethiweyo zokwakhiwa kwazo zihlala ziyi-aluminium. Nangona kunjalo, ayizizo zonke ii-electrolytic capacitors ezenziwe nge-aluminiyam. Enyanisweni, kukho iintlobo ezahlukeneyo ze-electrolytic capacitors ezenziwe ngokusebenzisa izinto ezahlukeneyo, ezifana ne-tantalum kunye ne-niobium. Kweli nqaku, siza kuntywila kwihlabathi le-aluminiyam electrolytic capacitors kwaye siphonononge ukuba zahluke njani kwezinye iindidi zee-electrolytic capacitors.
I-Aluminiyam i-electrolytic capacitors isetyenziswa ngokubanzi kwizixhobo zombane ezahlukeneyo kunye neenkqubo ngenxa yobuchule bazo obuphezulu, ubomi obude, kunye neendleko eziphantsi. Zakhiwe kusetyenziswa umaleko we-aluminium oxide njenge-dielectric, evumela ukuxinana okuphezulu kwe-capacitance. Ulwakhiwo lwe-aluminium electrolytic capacitor luqukethe i-anode eyenziwe nge-high-purity aluminiyam i-foil, ehlanganiswe ne-oxide layer, kunye ne-cathode eyenziwe ngolwelo oluqhubayo okanye izinto eziqinileyo. Ezi zixhobo zitywinwe kwii-aluminium casings ukuze zikhuseleke kwizinto zangaphandle.
Tantalum electrolytic capacitors, ngakolunye uhlangothi, zakhiwe ngokusebenzisa i-tantalum njengento ye-anode kunye ne-tantalum pentoxide layer njenge-dielectric. I-Tantalum capacitors inikezela ngexabiso eliphezulu le-capacitance kwi-compact size, ibenze bafaneleke kwizicelo ze-space-conscious. Nangona kunjalo, zibiza kakhulu kunei-aluminium electrolytic capacitorskwaye ziqhelene ngakumbi nokusilela ukuba zichatshazelwa zizitshixo zombane okanye umva polarity.
I-Niobium electrolytic capacitors ifana ne-tantalum capacitors, isebenzisa i-niobium njengento ye-anode kunye ne-niobium pentoxide layer njenge-dielectric. I-Niobium capacitors inexabiso eliphezulu le-capacitance kunye nokuvuza okuphantsi kwangoku, okwenza ukuba zilungele izicelo apho ukuzinza nokuthembeka kubaluleke kakhulu. Nangona kunjalo, njenge-tantalum capacitors, zibiza kakhulu kune-aluminium electrolytic capacitors.
Nangona i-aluminium i-electrolytic capacitors yolona hlobo luqhelekileyo olusetyenziswayo lwe-electrolytic capacitor, kubalulekile ukuqwalasela iimfuno ezithile zesicelo esinikiweyo xa ukhetha uhlobo lwe-capacitor oza kuyisebenzisa. Xa ukhetha i-capacitor efanelekileyo yoyilo oluthile lwe-elektroniki, izinto ezifana nexabiso le-capacitance, i-voltage rating, ubukhulu, iindleko, kunye nokuthembeka kufuneka kuthathelwe ingqalelo.
Ukuqukumbela, ayizizo zonke ii-electrolytic capacitors ezenziwe nge-aluminium. Ngelixa i-aluminium electrolytic capacitors lolona hlobo lusetyenziswa kakhulu lwe-electrolytic capacitor, i-tantalum electrolytic capacitors kunye ne-niobium electrolytic capacitors nazo zineempawu ezizodwa kunye neenzuzo. Xa ukhetha i-capacitors kwisicelo esithile, kubalulekile ukuqwalasela ngokucophelela iimfuno kwaye ukhethe uhlobo lwe-capacitor oluhlangabezana kakuhle nezo mfuno. Ngokuqonda umahluko phakathi kwezi ntlobo ezahlukeneyo ze-electrolytic capacitors, iinjineli kunye nabaqulunqi banokwenza izigqibo ezinolwazi xa bekhetha i-capacitor efanelekileyo kwi-design yabo ye-elektroniki.
