Xa kuziwa kwii-capacitors ze-electrolytic, izinto ezikhethwayo zokwakha zazo zihlala ziyi-aluminium. Nangona kunjalo, ayizizo zonke ii-capacitors ze-electrolytic ezenziwe nge-aluminium. Enyanisweni, kukho iintlobo ezahlukeneyo zee-capacitors ze-electrolytic ezenziwe ngezinto ezahlukeneyo, ezifana ne-tantalum kunye ne-niobium. Kweli nqaku, siza kungena kwihlabathi lee-capacitors ze-aluminium electrolytic kwaye sihlolisise indlela ezahluke ngayo kwezinye iintlobo zee-capacitors ze-electrolytic.
Ii-capacitor ze-aluminium electrolytic zisetyenziswa kakhulu kwizixhobo ezahlukeneyo ze-elektroniki kunye neenkqubo ngenxa yokuba zinamandla aphezulu, zihlala ixesha elide, kwaye zibiza kancinci. Zakhiwe kusetyenziswa umaleko we-aluminium oxide njenge-dielectric, nto leyo evumela ukuba kubekho uxinano olukhulu lwe-capacitance. Ulwakhiwo lwe-capacitor ye-aluminium electrolytic luqulathe i-anode eyenziwe nge-aluminium foil ecocekileyo kakhulu, egqunywe ngumaleko we-oxide, kunye ne-cathode eyenziwe ngolwelo oluqhubayo okanye izinto eziqinileyo. Ezi zinto emva koko zivalwa kwii-casing ze-aluminium ukuze zikhuseleke kwizinto zangaphandle.
Ii-capacitor ze-electrolytic zeTantalumKwelinye icala, zakhiwe kusetyenziswa i-tantalum njengesixhobo se-anode kunye ne-tantalum pentoxide layer njenge-dielectric. Ii-capacitors ze-Tantalum zibonelela ngexabiso eliphezulu le-capacitance ngobukhulu obuncinci, nto leyo ezenza zilungele ukusetyenziswa ngokujonga indawo. Nangona kunjalo, zibiza kakhulu kuneii-capacitors ze-aluminium electrolytickwaye zisengozini enkulu yokusilela xa zichaphazeleka zii-voltage spikes okanye i-reverse polarity.
Ii-capacitor ze-electrolytic ze-Niobium zifana nee-capacitors ze-tantalum, zisebenzisa i-niobium njengesixhobo se-anode kunye ne-niobium pentoxide layer njenge-dielectric. Ii-capacitors ze-Niobium zinexabiso eliphezulu le-capacitance kunye nomsinga ophantsi wokuvuza, nto leyo eyenza ukuba zilungele ukusetyenziswa apho uzinzo kunye nokuthembeka kubalulekile. Nangona kunjalo, njengee-capacitors ze-tantalum, zibiza kakhulu kunee-capacitors ze-aluminium electrolytic.
Nangona ii-capacitor ze-aluminium electrolytic zezona zisetyenziswa kakhulu kwi-capacitor ye-electrolytic, kubalulekile ukuqwalasela iimfuno ezithile zesicelo esithile xa ukhetha uhlobo lwe-capacitor oza kusebenzisa. Xa ukhetha i-capacitor efanelekileyo yoyilo oluthile lwe-elektroniki, izinto ezifana nexabiso le-capacitance, umlinganiselo we-voltage, ubungakanani, iindleko, kunye nokuthembeka kufuneka ziqwalaselwe.
Ukuqukumbela, ayizizo zonke ii-capacitor ze-electrolytic ezenziwe nge-aluminium. Nangona ii-capacitor ze-aluminium electrolytic zezona zisetyenziswa kakhulu kwi-capacitor ye-electrolytic, ii-capacitor ze-tantalum electrolytic kunye nee-capacitor ze-niobium electrolytic nazo zineempawu kunye neenzuzo ezikhethekileyo. Xa ukhetha ii-capacitor zesicelo esithile, kubalulekile ukuqwalasela ngononophelo iimfuno kwaye ukhethe uhlobo lwe-capacitor oluhlangabezana kakuhle nezo mfuno. Ngokuqonda umahluko phakathi kwezi ntlobo zahlukeneyo zee-capacitor ze-electrolytic, iinjineli kunye nabayili banokwenza izigqibo ezinolwazi xa bekhetha i-capacitor efanelekileyo kwiindlela zabo zoyilo lwe-elektroniki.
