Xa kuziwa ekukhetheni uhlobo olufanelekileyo lwe-capacitor kwisicelo sombane, ukhetho lunokuthi lube ludizzy.Enye yeentlobo eziqhelekileyo ze-capacitors ezisetyenziswa kwiisekethe ze-elektroniki yi-electrolytic capacitor.Ngaphakathi kolu didi, kukho iindidi ezimbini eziphambili: i-aluminium electrolytic capacitors kunye ne-polymer electrolytic capacitors.Ukuqonda umahluko phakathi kwezi ntlobo zimbini ze-capacitors kubalulekile ekukhetheni i-capacitor echanekileyo kwisicelo esithile.
I-Aluminiyam i-electrolytic capacitorszezona ziqhelekileyo kwaye zisetyenziswa ngokubanzi uhlobo lwe-electrolytic capacitors.Baziwa ngexabiso labo eliphezulu le-capacitance kunye nokukwazi ukuphatha amanqanaba ombane aphezulu.Ezi capacitors zenziwe ngokusebenzisa iphepha elifakwe kwi-electrolyte njenge-dielectric kunye ne-aluminium foil njenge-electrodes.I-electrolyte idla ngokuba yinto engamanzi okanye ijeli, kwaye yintsebenziswano phakathi kwe-electrolyte kunye nefoyile ye-aluminium evumela ukuba ezi capacitors zigcine kwaye zikhulule amandla ombane.
Iipolymer electrolytic capacitors, kwelinye icala, luhlobo olutsha, oluphezulu ngakumbi lwe-electrolytic capacitor.Esikhundleni sokusebenzisa i-electrolyte ye-liquid okanye i-gel, i-polymer capacitors isebenzisa i-polymer conductive eqinile njenge-electrolyte, okubangela ukuzinza okungcono kunye nokunciphisa ukuchasana kwangaphakathi.Ukusetyenziswa kobuchwephesha obuqinileyo kwi-polymer capacitors kunokunyusa ukuthembeka, ukwandisa ubomi benkonzo, kunye nokubonelela ngokusebenza okungcono kwi-high-frequency kunye ne-high-temperature applications.
Omnye umahluko ophambili phakathii-aluminium electrolytic capacitorskunye neepolymer electrolytic capacitors bubomi babo benkonzo.IAluminium electrolytic capacitors ngokubanzi inobomi obufutshane kunepolymer capacitors kwaye isesichengeni sokusilela ngenxa yezinto ezifana nobushushu obuphezulu, uxinzelelo lombane, kunye neripple current.I-polymer capacitors, ngakolunye uhlangothi, inobomi obude benkonzo kwaye yenzelwe ukujamelana neemeko zokusebenza ezinzima, ezizenza zilungele ukusetyenziswa kwizicelo ezifunwayo.
Omnye umehluko obalulekileyo yi-ESR (i-requivalent series resistance) yee-capacitors ezimbini.I-Aluminium electrolytic capacitors ine-ESR ephezulu xa kuthelekiswa ne-polymer capacitors.Oku kuthetha ukuba i-polymer capacitors inokumelana okuphantsi kwangaphakathi, okukhokelela ekusebenzeni okungcono ngokuphathwa kwe-ripple yangoku, ukuveliswa kobushushu kunye nokuchithwa kwamandla.
Ngokumalunga nobukhulu kunye nobunzima, ii-polymer capacitors zincinci kwaye zikhaphukhaphu kune-aluminium capacitors ye-capacitance efanayo kunye ne-voltage rating.Oku kubenza bafaneleke ngakumbi kwi-compact kunye nezixhobo zombane ezikhaphukhaphu, apho indawo kunye nobunzima zizinto eziphambili zokuqwalaselwa.
Isishwankathelo, ngelixa i-aluminium electrolytic capacitors ibiyeyona nto ikhethwayo iminyaka emininzi ngenxa yamaxabiso aphezulu omthamo kunye namazinga ombane, iipolymer electrolytic capacitors zibonelela ngezinto ezininzi ezilungileyo malunga nobomi obude, ukusebenza kunye nobukhulu.Ukukhetha phakathi kweentlobo ezimbini ze-capacitors kuxhomekeke kwiimfuno ezithile zesicelo, ezifana neemeko zokusebenza, izithintelo zendawo, kunye neemfuno zokusebenza.
Lilonke, zombini i-aluminiyam i-electrolytic capacitors kunye ne-polymer electrolytic capacitors zineenzuzo zazo kunye nokungalunganga.Ukuze ukhethe uhlobo olufanelekileyo lwe-capacitor kwisicelo, kubalulekile ukuqwalasela ngokucophelela iimfuno ezithile kunye neemeko zokusebenza zesekethe ye-elektroniki.Njengoko itekhnoloji iqhubela phambili, ii-polymer electrolytic capacitors ziya zithandwa kakhulu ngenxa yokusebenza kwazo okuphuculweyo kunye nokuthembeka, okuzenza zibe yindlela enokusebenziseka kwi-aluminiyam electrolytic capacitors yemveli kwizicelo ezininzi ze-elektroniki.
