Nā capacitors seramikaua hoʻohana nui ʻia i nā lako uila pūʻali koa, nā lako kamaʻilio ʻōnaehana, nā lako mana ʻoihana, nā uila uila, nā huahana uila mea kūʻai aku, etc.
ʻO ka haʻahaʻa haʻahaʻa kūloko o nā capacitors seramika he mea kōkua nui ia no ka ripple haʻahaʻa haʻahaʻa a hiki ke hoʻopaʻa i ka walaʻau kiʻekiʻe-frequency, akā hiki ke capacitance o nā capacitors ceramic attenuates i ka uila kiʻekiʻe.No ke aha mai?
ʻO ka capacitance decay o nā capacitors ceramic ma ka volta kiʻekiʻe e pili ana i nā waiwai o nā mea i hoʻohana ʻia i nā capacitors seramika.
Hana ʻia nā capacitors āpau i ʻelua conductors, i hoʻokaʻawale ʻia mai kekahi i kekahi.Ke hoʻohana ʻia ka volta ma waena o nā mea hoʻokele ʻelua, ua hoʻokumu ʻia kahi māla uila ma waena o nā mea hoʻokele ʻelua.Ma lalo o ka hana o ke kahua uila, e hōʻiliʻili nā uku dielectric ma waena o nā conductors i ke kuhikuhi o nā conductors ʻelua.ʻO ke kahua uila i hana ʻia e lākou he kūʻē i ke kahua uila mua, a ʻoi aku ka nāwaliwali o ke kahua uila i loko o ka dielectric.ʻO ka lakio o ke kahua uila i hoʻohana mua ʻia i ka ikaika o ke kahua uila i ka dielectric ʻo ia ka permittivity pili o ka dielectric.
ʻO ka mea i hoʻohana ʻia i ka capacitor ceramic he ceramic me ka dielectric mau kiʻekiʻe, ʻo ka mea nui he barium titanate, ʻo ka mea hoʻomau dielectric pili ma kahi o 5000, a ʻoi aku ka kiʻekiʻe o ka dielectric mau.
No ka mea hiki i ka dielectric ke hoʻemi i ka ikaika o ke kahua uila, ʻaʻole maʻalahi ke wāwahi ʻia, no laila hiki ke hoʻomaikaʻi ʻia ka hiki o ka capacitor e mālama i ka uku uila, ʻo ia hoʻi, hoʻomaikaʻi ʻia ka capacitance.Eia nō naʻe, ma lalo o ka uila kiʻekiʻe, e hoʻomau ka ikaika o ke kahua uila i ka dielectric, a e emi mālie ka paʻa dielectric, ʻo ia ke kumu e pohō ai ka capacitance o nā capacitors ceramic ma lalo o ka volta kiʻekiʻe.
E koho i kahi mea hana hilinaʻi i ke kūʻai ʻana i nā capacitor seramika hiki ke pale i ka nui o nā pilikia pono ʻole.ʻAʻole wale ʻo JEC mea hana mua i nā hiʻohiʻona piha o nā capacitors seramika me ka maikaʻi i hōʻoiaʻiʻo ʻia, akā hāʻawi pū kekahi i ka hopohopo ʻole ma hope o ke kūʻai aku.Ua hala nā hale hana JEC ISO9001: 2015 hōʻoia ʻōnaehana hoʻokele maikaʻi;Ua hala nā capacitors palekana JEC (X capacitors a me Y capacitors) a me nā varistors i ka hōʻoia o nā ʻāina like ʻole;ʻO nā capacitors ceramic JEC, nā capacitors kiʻiʻoniʻoni a me nā capacitors super e pili ana me nā hōʻailona kalapona haʻahaʻa.
