I ka hiki ʻana mai i ke koho ʻana i ke ʻano kūpono o ka capacitor no kahi noi uila, hiki i nā koho ke lilo pinepine. ʻO kekahi o nā ʻano capacitors maʻamau i hoʻohana ʻia i nā kaapuni uila ʻo ia ka electrolytic capacitor. I loko o kēia māhele, ʻelua mau ʻano subtypes: nā capacitors electrolytic aluminika a me nā capacitors electrolytic polymer. He mea koʻikoʻi ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau ʻano capacitor ʻelua i ke koho ʻana i ka capacitor kūpono no kahi noi kikoʻī.
Aluminum electrolytic capacitorsʻO ia nā ʻano kuʻuna a hoʻohana nui ʻia o nā capacitors electrolytic. Ua ʻike ʻia lākou no kā lākou waiwai capacitance kiʻekiʻe a hiki ke mālama i nā kiʻekiʻe voltage kiʻekiʻe. Hana ʻia kēia mau capacitors me ka pepa i hoʻopili ʻia me ka electrolyte e like me ka dielectric a me ka alumini foil e like me nā electrodes. ʻO ka electrolyte ka mea maʻamau i ka wai a i ʻole ka gel, a ʻo ia ka pilina ma waena o ka electrolyte a me ka alumini alumini e hiki ai i kēia mau capacitors ke mālama a hoʻokuʻu i ka ikehu uila.
ʻO nā capacitors electrolytic polymer, ma ka ʻaoʻao ʻē aʻe, he ʻano hou, ʻoi aku ka holomua o ka capacitor electrolytic. Ma kahi o ka hoʻohana ʻana i ka wai a i ʻole ka gel electrolyte, hoʻohana nā capacitor polymer i kahi polymer conductive paʻa e like me ka electrolyte, e hopena i ka paʻa maikaʻi a me ka haʻahaʻa haʻahaʻa o loko. ʻO ka hoʻohana ʻana i ka ʻenehana paʻa paʻa i nā capacitors polymer hiki ke hoʻonui i ka hilinaʻi, hoʻonui i ke ola lawelawe, a hāʻawi i ka hana ʻoi aku ka maikaʻi ma nā noi kiʻekiʻe a me ke kiʻekiʻe.
ʻO kekahi o nā ʻokoʻa nui ma waenaalumina electrolytic capacitorsa ʻo nā capacitors electrolytic polymer ko lākou ola lawelawe. ʻOi aku ka pōkole o nā capacitors electrolytic alumini ma mua o nā capacitors polymer a ʻoi aku ka maʻalahi o ka hāʻule ʻana ma muli o nā kumu e like me ke kiʻekiʻe o ka wela, ke koʻikoʻi o ka uila, a me ka ripple current. ʻO nā capacitors Polymer, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka lōʻihi o ka lawelawe ʻana a ua hoʻolālā ʻia e kū i nā kūlana hana ʻoi aku ka paʻakikī, e kūpono iā lākou no ka hoʻohana ʻana i nā noi koi.
ʻO kekahi ʻokoʻa koʻikoʻi ʻo ka ESR (equivalent series resistance) o nā capacitors ʻelua. ʻOi aku ka nui o ka ESR i nā capacitors electrolytic alumini i hoʻohālikelike ʻia me nā capacitors polymer. ʻO ia ke ʻano he haʻahaʻa haʻahaʻa i loko o nā capacitors polymer, e hopena i ka hana ʻoi aku ka maikaʻi ma ke ʻano o ka hoʻohana ʻana i ka ripple o kēia manawa, ka hana wela a me ka hoʻopau ʻana i ka mana.
Ma ke ʻano o ka nui a me ke kaumaha, ʻoi aku ka liʻiliʻi o nā capacitor polymer a ʻoi aku ka māmā ma mua o nā capacitors alumini o ka capacitance like a me ka helu volta. ʻOi aku ka maikaʻi o kēia no nā mea uila uila paʻa a māmā, kahi e noʻonoʻo nui ai ka lewa a me ke kaumaha.
I ka hōʻuluʻulu ʻana, ʻoiai ʻo nā capacitor electrolytic alumini ka mea i koho ʻia no nā makahiki he nui ma muli o ko lākou mau helu capacitance kiʻekiʻe a me nā helu voltage, hāʻawi nā polymer electrolytic capacitors i nā pono i nā ʻōlelo o ka lōʻihi, ka hana, a me ka nui. ʻO ke koho ʻana ma waena o nā ʻano capacitors ʻelua e pili ana i nā koi kikoʻī o ka noi, e like me nā kūlana hana, nā palena ākea, a me nā koi hana.
ʻO nā mea āpau, loaʻa nā capacitors electrolytic aluminika a me nā capacitors electrolytic polymer i kā lākou pono ponoʻī a me nā hemahema. No ke koho ʻana i ke ʻano capacitor kūpono loa no kahi noi, pono e noʻonoʻo pono i nā koi kikoʻī a me nā kūlana hana o ke kaapuni uila. Ke hoʻomau nei ka ʻenehana i ka holomua, ke ulu nui nei nā capacitors electrolytic polymer ma muli o kā lākou hoʻomaikaʻi ʻana i ka hana a me ka hilinaʻi, e hoʻolilo iā lākou i mea kūpono i nā capacitors electrolytic alumini ma nā noi uila he nui.
