Aluminium electrolytic capacitorsziyingxenye ebalulekile yemishini eminingi kagesi futhi zidlala indima ebalulekile ekugcineni nasekukhipheni amandla kagesi. Kodwa-ke, naphezu kokubaluleka kwawo, ama-capacitor avame ukuhluleka, okubangela ukwehluleka futhi okungase kulimaze lonke uhlelo. Ukuqonda izimbangela zokuhluleka kwe-capacitor kubalulekile ekuqinisekiseni ukwethembeka nokuphila isikhathi eside kwemishini kagesi.
Kunezizathu eziningana zokuthi kungani ama-capacitor evame ukuhluleka, enye yezinto ezivame kakhulu ukusetshenziswai-aluminium electrolytic capacitors. Lawa ma-capacitor asetshenziswa kakhulu kumasekhethi ngenxa yamandla awo aphezulu, izindleko eziphansi, kanye nezilinganiso zamandla kagesi aphezulu uma kuqhathaniswa. Kodwa-ke, uma kuqhathaniswa nezinye izinhlobo ze-capacitor, zinesikhathi esilinganiselwe sokuphila, okungaholela ekuhlulekeni okuvamile kumishini kagesi.
Esinye sezizathu eziyinhloko ezenza ama-aluminium electrolytic capacitor ahluleke ukuzwela kwawo ekuguquguqukeni kwezinga lokushisa. Lawa ma-capacitor azwela kakhulu ekushintsheni kwezinga lokushisa, futhi ukuchayeka emazingeni okushisa aphezulu kungabangela ukuthi i-electrolyte ngaphakathi kwe-capacitor yome, okuholela ekulahlekelweni kwe-capacitance nokwanda kokuvuza kwamanje. Lokhu kungenza ukuthi i-capacitor yehle futhi ekugcineni ibangele ukuthi yehluleke.
Esinye isici esinomthelela ekuhlulekeni kwe-aluminium electrolytic capacitor ukuthambekela kwabo kokunciphisa ngokuhamba kwesikhathi. Ama-electrolyte asetshenziswa kulawa ma-capacitor asengozini yokuwohloka kwamakhemikhali, okungabangelwa izici ezihlukahlukene ezifana namazinga okushisa aphezulu okusebenza, ukucindezeleka kwamandla kagesi, nokuchayeka ezintweni ezingcolisa imvelo. Njengoba i-electrolyte iwohloka, i-capacitance ne-ESR (ukumelana nochungechunge olulinganayo) ye-capacitor iyashintsha, okuholela ekunciphiseni ukusebenza nokuthembeka.
Ngaphezu kwezinga lokushisa nokuguga, esinye isizathu esenza i-aluminium electrolytic capacitor ivame ukuhluleka wukuthambekela kwabo ekukhuphukeni kwe-voltage kanye ne-ripple current. Lawa ma-capacitor avame ukusetshenziswa kumasekhethi okuphakelwa kukagesi lapho evezwa amaza agelezayo aphezulu nama-voltage spikes. Ngokuhamba kwesikhathi, ukuchayeka ngokuphindaphindiwe emisinga ephezulu kanye nama-voltages kungabangela izingxenye zangaphakathi ze-capacitor ukuba ziwohloke, okuholela ekunciphiseni amandla kanye nokwanda kwe-ESR.
Ngaphezu kwalokho, umklamo kanye nekhwalithi yei-aluminium electrolytic capacitorsizophinde ithinte ukwethembeka kanye nezinga lokuhluleka. Ama-capacitor ashibhile noma asezingeni eliphansi angase asebenzise izinto zekhwalithi ephansi nezinqubo zokukhiqiza, okuholela emathubeni aphezulu okwehluleka ngaphambi kwesikhathi. Ukusebenzisa ama-capacitor ekhwalithi ephezulu, akalwe ngokufanele emishinini kagesi kubalulekile ekunciphiseni ubungozi bokwehluleka.
Ukuze unciphise ingozi yokuhluleka kwe-capacitor, kubalulekile ukucabangela izimo nendawo lapho i-capacitor izosetshenziswa khona. Ukuphatha okushisayo okufanelekile, ukwehla kwamandla kagesi, nokukhethwa ngokucophelela kwama-capacitor ngokusekelwe ekucacisweni kwawo kanye nezilinganiso zokuthembeka kungasiza ukunweba impilo yabo yesevisi futhi kunciphise ingozi yokwehluleka.
Kafushane, ama-aluminium electrolytic capacitor awumthombo ovamile wokwehluleka emishinini kagesi ngenxa yokuzwela kwawo ezingeni lokushisa, ukuguga, ukucindezelwa kwamandla kagesi, kanye namandla akhona. Ngokuqonda lezi zici nokuthatha izinyathelo zokuphepha ezidingekayo, njengokukhetha ama-capacitor ekhwalithi ephezulu nokusebenzisa izimo zokusebenza ezifanele, unganciphisa amathuba okuhluleka kwe-capacitor futhi uqinisekise ukuthembeka kwemishini yakho ye-elekthronikhi.
