Nīnau: Hoʻopilikia ʻia nā capacitors seramika e nā hanana kahiko
Hoʻopili ʻia nā capacitors seramika e nā hanana kahiko e pili ana i nā loli i ka hoʻolālā kristal dielectric, e hōʻike ana iā ia iho he hoʻololi i ka capacitance a me ka dissipation factor ma hope o ka puhi mua ʻana o ka mea dielectric.Kūlike me nā hiʻohiʻona i hoʻokumu ʻia, ʻaʻole liʻiliʻi nā mea dielectric EIA Class I a ua ʻike nui ʻia ʻo ia ʻaʻole i ʻelemakule, ʻoiai ʻo nā mea dielectric EIA Class II e hoʻopilikia ʻia a me nā mea EIA Class III e hoʻopilikia nui ʻia.Hiki ke hoʻihoʻi hou ʻia kēia kaʻina hana ʻelemakule (a i ʻole ka mea "de-aging") ma o ka ʻike ʻana i nā wela ma luna o ka mahana Curie o ka dielectric no kahi manawa lōʻihi e hiki ai ke hana hou i ka hale aniani;ʻo ke kiʻekiʻe o ka mahana, ʻoi aku ka pōkole o ka manawa e pono ai.No ka mea ʻoi aku ka haʻahaʻa o ka mahana Curie o nā dielectrics seramika ma mua o ka mea i ʻike ʻia ma nā kaʻina hana kūʻai he nui, ʻoi aku paha ka liʻiliʻi o ka ʻelemakule i ka wā o ka ʻākoakoa.
Hōʻike pinepine ʻia kēia ʻano hana kahiko o kahi ʻāpana ma ke ʻano he pākēneka o ka hoʻololi ʻana i ka capacitance no nā makahiki he ʻumi o nā hola, e pili ana i ka capacitance i ana ʻia i ka "wela hope loa," ʻo ka manawa hope loa i wela ai ka mea ma luna o kona mahana Curie lōʻihi e hoʻololi loa i kona aniani. hale kūkulu.Ma nā huaʻōlelo ʻē aʻe, ʻo ka capacitor me ka helu ʻelemakule o (-)5%, i ana ʻia ma 100uF i ka mokuʻāina "oven fresh", e manaʻo ʻia e ana ma kahi o 95,90 a me 85uF ma hope o 1, 10 a me 100 mau hola i waho o ka umu. , pakahi.
ʻOiaʻiʻo, hoʻāla kēia i ka nīnau no ke ʻano o ka capacitance nominal o ka mea e pono ai, a inā e loli mau ana kēlā nui, e hoʻohana ʻia ka ʻāpana ma ka papa inā ʻaʻole i hoʻohana ʻia i loko o kāna waihona mua.ʻO nā kūlana o ka ʻoihana EIA-521 a me IEC-384-9 e hoʻoponopono i kēia pilikia, me ka ʻōlelo maoli ʻana e hiki i ka ʻāpana ke hōʻea i kāna waiwai hoʻomanawanui i kuhikuhi ʻia 1000 mau hola (ma kahi o 42 mau lā) ma hope o ka hoʻomehana ʻana.ʻO ka hōʻailona ʻumi makahiki e hiki mai ana (10K a me 100K mau hola) e unuhi i kahi liʻiliʻi ma mua o 1 makahiki a ma kahi liʻiliʻi ma luna o 11 mau makahiki.No ka hoʻopiʻi hou ʻana i nā mea, hiki ke kaʻina hana ʻelemakule ma kahi wikiwiki e pili ana i ka mahana;a hiki i ka mahana Curie o ka dielectric, ʻo ka piʻi ʻana o ka wela o ka mea maʻamau e hoʻolalelale i ke kaʻina hana ʻelemakule.
No ka mea hiki i nā mea ʻelemakule ke hōʻike i nā mea hana ma waho o kā lākou ʻae ʻia, pono e ʻike nā mea hoʻolālā huahana a me nā mea hōʻike hana i kēia ʻoiaʻiʻo;ʻO ka hoʻāʻo ʻana i nā ʻāpana i hoʻokuʻu hou ʻia e manaʻo ʻia he ʻoi aku ke kiʻekiʻe o nā waiwai capacitance, a pono e lawa ka palena o ka hoʻolālā e hoʻokō i ka hana maʻamau o ka hāmeʻa i kona mau makahiki.He laʻana maikaʻi nā kaapuni hoʻololi mana no kahi e hiki ai i kēia hopena ke hoʻopilikia nui, ʻoiai ʻo nā capacitor seramika e hoʻopau nui i nā puka mana o ia mau kaapuni, ma ke ʻano he ʻāpana pūnaewele uku a i ʻole he mea kānana.ʻO nā ʻōnaehana i ʻike paʻa ʻia ma lalo o ka mana o ka ʻelemakule capacitor i ka wā o ka hui ʻana e liʻiliʻi ke kūpaʻa i ka manawa, no ka mea, ʻo ka nalowale o ka capacitance ma muli o ka ʻelemakule e pili ana i ka dinamika o ka loop control.ʻO ka mea nui, inā he mea nui nā waiwai capacitance paʻa i ka manawa, e pale i ka hoʻohana ʻana i nā capacitor ʻike ʻia.
ʻO Zhejiang NeoDen Technology Co., LTD., i hoʻokumu ʻia i ka makahiki 2010, aia mākou i kahi kūlana maikaʻi ʻaʻole wale e hāʻawi iā ʻoe i ka mīkini pnp kiʻekiʻe kiʻekiʻe, akā ʻo ka lawelawe maikaʻi loa ma hope o ke kūʻai aku.E hāʻawi nā ʻenekini hoʻomaʻamaʻa maikaʻi iā ʻoe i ke kākoʻo ʻenehana.
Hiki i nā ʻenekini 10 ikaika ma hope o ke kūʻai aku ke pane aku i nā nīnau a me nā nīnau i loko o 8 mau hola.
Hiki ke hāʻawi ʻia nā hoʻonā ʻoihana i loko o 24 mau hola i ka lā hana a me nā lā hoʻomaha.
