ʻO nā chip inductors, i ʻike ʻia ʻo ka mana inductors, ʻo ia kekahi o nā mea i hoʻohana pinepine ʻia i nā huahana uila, e hōʻike ana i ka miniaturization, kiʻekiʻe kiʻekiʻe, kiʻekiʻe ka mālama ʻana i ka ikehu a me ka haʻahaʻa haʻahaʻa.Kūʻai pinepine ʻia i nā hale hana PCBA.Ke koho ʻana i kahi inductor chip, pono e noʻonoʻo ʻia nā ʻāpana hana (e like me ka inductance, ka helu o kēia manawa, ka mea maikaʻi, a me nā mea ʻē aʻe) a me ke ʻano kumu.
I. ʻO nā ʻāpana hana inductor chip
1. ʻO ka inductance o nā hiʻohiʻona maʻemaʻe: inductor ma muli o ka hoʻololi ʻana i ka mahana o ke kaiapuni 1 ℃ i hoʻokumu ʻia e ka inductance o ka hoʻoponopono hou ʻana o △ L / △ t a me ka waiwai L inductance kumu i hoʻohālikelike ʻia i ka waiwai o ka ʻōnaehana wela inductor a1, a1 = △ L / L△ t.Ma waho aʻe o ka coefficient mahana inductor e hoʻoholo i kona kūpaʻa, akā e mālama pono i ka inductance o ka haʻalulu mechanical a me ka ʻelemakule ma muli o ka loli.
2. Ke kū'ē i ka ikaika voli a me ka haʻahaʻa hana pale: No ka inductive mea me ke kū'ēʻana i ka volta ikaika pono e koho e hoʻohana i ka pūʻolo mea e pale aku i ka harshness o kiʻekiʻe voltage, maʻamau o ka maikaʻi loa voltage kuʻi inductive mea, moisture pale hana 'oi aku ka maikaʻi. .
3. Inductance a me ka ʻae ʻia ʻana: pili ka inductance i ka ʻikepili nominal o ka inductance i ʻike ʻia e ke alapine e koi ʻia e ka maʻamau ʻenehana huahana.ʻO ka ʻāpana o ka inductance ʻo Henry, millihen, microhen, nanohen, hoʻokaʻawale ʻia i: F pae (± 1%);pae G (± 2%);H pae (± 3%);J pae (± 5%);K pae (± 10%);L pae (± 15%);M pae (± 20%);P pae (± 25%);N ka pae (± 30%);ʻo ka mea i hoʻohana nui ʻia ʻo ia ka pae J, K, M.
4. ʻIke pinepine: ʻo ka ʻike pololei ʻana i ka nui o nā mea inductor L, Q, DCR waiwai, pono e hoʻohui mua i ka alternating current i ka inductor i hoʻāʻo ʻia e like me nā mea i hoʻolako ʻia, ʻoi aku ka pili o ke alapine o kēia manawa i ke alapine hana maoli o kēia inductor. , ʻoi aku ka maikaʻi.Inā liʻiliʻi ka ʻāpana waiwai inductor e like me ka pae nahum, pono e nānā ʻia ke alapine o nā mea hana e ana ʻia a hiki i 3G.
5. Ke kū'ē DC: Ma waho aʻe o ka mana inductor lako e ho'āʻo DC kū'ē, kekahi mau mea inductor mea e like me ka pono e hoakaka i ka palena kiʻekiʻe DC kū'ē, maʻamau ka liʻiliʻi ka oi makemake.
6. nui ka hana o kēia manawa: e lawe maʻamau i ka 1.25 a i ka 1.5 manawa o ka manawa i helu ʻia o ka inductor e like me ka nui o ka hana o kēia manawa, pono e hoʻemi ʻia e 50% e hoʻohana ai i mea palekana a hilinaʻi.
II.ʻO ke kumu hoʻohālike chip inductor
E koho i nā inductors no nā noi mana lawe lima, ʻo nā mea koʻikoʻi ʻekolu e noʻonoʻo ai: ka nui, ka nui, ke kolu a i ʻole ka nui.
ʻO ka ʻāpana o ka papa kaapuni o nā kelepona paʻa loa, ʻoi aku ka nui o nā hiʻohiʻona e like me nā mea pāʻani MP3, TV a me nā wikiō i hoʻohui ʻia i ke kelepona.ʻO ka hoʻonui ʻana i ka hana e hoʻonui i ka hoʻohana ʻana o ka pākaukau.ʻO ka hopena, ʻo nā modula i hoʻohana mua ʻia e nā mea hoʻoponopono laina a i ʻole i hoʻopili pololei ʻia i ka pākaukau e pono ai i nā hopena kūpono.ʻO ka hana mua i ka hopena ʻoi aku ka maikaʻi o ka hoʻohana ʻana i kahi mea hoʻololi magnetic buck.E like me ka manaʻo o ka inoa, pono kahi inductor i kēia manawa.
ʻO nā kikoʻī nui o kahi inductor, ʻokoʻa ka nui, ʻo ia ka waiwai inductance i ke alapine hoʻololi, DC impedance (DCR) o ka coil, helu saturation i kēia manawa, helu rms i kēia manawa, AC impedance (ESR), a me Q-factor.Ma muli o ka noi, he mea nui hoʻi ke koho ʻana i ke ʻano inductor - pale a ʻaʻole pale.
Ua like ka nānā aku o nā chip inductors, a ʻaʻole hiki ke ʻike i ka maikaʻi.I ka ʻoiaʻiʻo, hiki iā ʻoe ke ana i ka inductance o nā chip inductors me kahi multimeter, a ʻo ka inductance maʻamau o nā inductors maikaʻi ʻole e hoʻokō i nā koi, a ʻoi aku ka nui o ka hewa.
