Uma kukhulunywa ngama-electrolytic capacitor, into ekhethwayo yokwakha imvamisa i-aluminium.Kodwa-ke, akuwona wonke ama-electrolytic capacitor enziwe nge-aluminium.Eqinisweni, kunezinhlobo ezahlukene ze-electrolytic capacitor ezenziwe kusetshenziswa izinto ezahlukene, njenge-tantalum ne-niobium.Kulesi sihloko, sizongena emhlabeni wama-capacitor e-aluminium electrolytic futhi sihlole ukuthi ahluke kanjani kwezinye izinhlobo zama-electrolytic capacitor.
Ama-Aluminium electrolytic capacitor asetshenziswa kakhulu emishinini nasezinhlelweni ze-elekthronikhi ngenxa yamandla awo aphezulu, impilo ende, kanye nezindleko eziphansi uma kuqhathaniswa.Akhiwe kusetshenziswa isendlalelo se-aluminium oxide njenge-dielectric, okuvumela ukuminyana okuphezulu kwe-capacitance.Isakhiwo se-aluminium electrolytic capacitor siqukethe i-anode eyenziwe nge-high-purity aluminium foil, ehlanganiswe nongqimba lwe-oxide, kanye ne-cathode eyenziwe ngoketshezi olusebenzayo noma okuqinile.Lezi zingxenye zibe sezivalwa emabhokisini e-aluminium ukuze zivikeleke ezintweni ezingaphandle.
I-Tantalum electrolytic capacitors, ngakolunye uhlangothi, zakhiwe kusetshenziswa i-tantalum njenge-anode material kanye nongqimba lwe-tantalum pentoxide njenge-dielectric.Ama-Tantalum capacitor anikezela ngamavelu e-capacitance aphezulu ngosayizi ohlangene, okuwenza afanelekele izinhlelo zokusebenza ezikhathalela isikhala.Nokho, ayabiza kakhulu kunaleyoi-aluminium electrolytic capacitorsfuthi ajwayele ukwehluleka uma ethintwa ama-voltage spikes noma i-polarity ehlehlayo.
I-Niobium electrolytic capacitor ifana ne-tantalum capacitor, isebenzisa i-niobium njengento ye-anode kanye nongqimba lwe-niobium pentoxide njenge-dielectric.Ama-Niobium capacitor anamanani aphezulu we-capacitance kanye nokuvuza okuphansi kwamanje, okuwenza afanelekele izinhlelo zokusebenza lapho ukuzinza nokuthembeka kubaluleke kakhulu.Kodwa-ke, njengama-tantalum capacitor, abiza kakhulu kune-aluminium electrolytic capacitor.
Nakuba i-aluminium electrolytic capacitor kuwuhlobo oluvame ukusetshenziswa kakhulu lwe-electrolytic capacitor, kubalulekile ukucabangela izidingo ezithile zohlelo olunikeziwe lapho kukhethwa uhlobo lwe-capacitor ozoyisebenzisa.Lapho ukhetha i-capacitor efanelekile yomklamo othile we-elekthronikhi, izici ezifana nevelu ye-capacitance, isilinganiso se-voltage, usayizi, izindleko, nokuthembeka kufanele kucatshangelwe.
Sengiphetha, akuwona wonke ama-electrolytic capacitor enziwe nge-aluminium.Nakuba i-aluminium electrolytic capacitor iwuhlobo olusetshenziswa kakhulu lwe-electrolytic capacitor, i-tantalum electrolytic capacitor kanye nama-niobium electrolytic capacitor nawo anezakhiwo nezinzuzo eziyingqayizivele.Uma ukhetha ama-capacitor ohlelo lokusebenza oluthile, kubalulekile ukucabangela ngokucophelela izidingo bese ukhetha uhlobo lwe-capacitor oluhlangabezana kangcono nalezo zidingo.Ngokuqonda umehluko phakathi kwalezi zinhlobo ezahlukene zama-electrolytic capacitor, onjiniyela nabaklami bangenza izinqumo ezinolwazi lapho bekhetha i-capacitor efanelekile yemiklamo yabo ye-elekthronikhi.
