ʻO nā hiʻohiʻona waiwai o nā inductors mana uea a me ka ʻokoʻa ma waena o nā inductors chip a me nā inductors ʻeha uea | GETWELL

ʻO ka mea mua, he aha ka inductor ʻeha uea?

Nui nā ʻano o nā inductors, e like me: mana inductors, laminated inductors, uea eha inductors, etc.

ʻO ka inductor ʻeha uea kekahi o nā inductors chip. ʻO ia kahi ʻāpana electromagnetic induction ʻeha me nā uea insulated, a ʻo ia kekahi o nā mea maʻamau i hoʻohana ʻia i nā kaapuni. Hoʻohana nui ʻia i ka micro TV, LCD TV, pahupaʻiwikiō, VRC portable, leo kaʻa, lekiō lahilahi, TV tuner, kelepona paʻa, etc.

He nui nā pono o nā inductors Wirewound:

1. Hoʻopili ka hiʻohiʻona a me ka nui i nā kūlana EIA (Electronic Industry Association), a he nui nā ʻano o nā pūʻolo, hiki ke hoʻopili ʻia i nā papa kaapuni me nā koi like ʻole.

2. Ili mauna hiʻona, no laila, he maikaʻi solderability, a hiki ke hoʻolako lipine pūʻolo no ka 'akomi hui.

3. Kūleʻa wela.

4. Haʻahaʻa magnetic flux leakage, haʻahaʻa DC kū'ē, a kiʻekiʻe o kēia manawa kū'ē.

5. Kiʻekiʻe precision a me ka haʻahaʻa poho (ʻo ia hoʻi, nui Q waiwai).

6. He mea maʻalahi ka hana hana a he haʻahaʻa ke kumukūʻai.

ʻO ka hana maʻamau o ka winding inductance:

Kānana, oscillation, lohi, notch, etc., e waiho wale: "pass DC, block AC".

ʻO ke ʻano o ka inductance wiliwili:

ʻO ka inductance wili i loko o kahi iwi, kahi wili, kahi kumu magnetic, kahi koʻokoʻo magnetic, a me kahi kumu hao.

ʻAʻole hoʻopaʻa ʻia ka mea koʻikoʻi magnetic o ka uea eha mana inductor . Loaʻa i ka puʻupuʻu magnetic kahi puʻupuʻu magnetic. ʻOkoʻa nā mea koʻikoʻi magnetic, ʻokoʻa maoli ka flux magnetic, ka mea i hopena i ka inductance o ka inductor ʻeha uea. ʻOi aku ka kiʻekiʻe o ka magnetic permeability o ka magnetic core, ʻoi aku ka nui o ka inductance o ka uea ʻeha inductor! ʻOkoʻa kumu kumu hoʻohua pū kekahi okoa uea eha inductances. No ka laʻana, ʻo ka inductance o kā mākou China Gewei Electronics he uwea ʻeha chip ferrite. Inductors, uea eha chip ceramic inductors, etc. He elua kumu waiwai i loko o ka uea eha inductor, a me keia mau mea elua i pili i ka hana kumu o ka uea eha inductor, 'o ia hoʻi, ke kumu magnetic a me ka uea. ʻAʻole ʻōlelo ʻo Xiaobian Jin Haode e pili ana i ka uea, ʻo ka mea nui no ka poʻe a pau e nānā i ka mana o ke kumu magnetic ma ka inductor ʻeha.

SMD mana chip inductor

ʻO ka ʻokoʻa ma waena o nā inductors laminated SMD a me nā inductors ʻeha uea i hōʻike nui ʻia ma nā ʻano 5: ʻokoʻa i ke kaʻina hana: Ua hoʻokumu ʻia nā inductors ʻeha uea ma luna o ke kaʻina hana uea maʻamau inductor, e hoʻohuli ana i nā mea hoʻokomo kuʻuna i loko o ka SMD packaging, a ma i ka manawa like Hoʻemi ʻia ka nui o ka inductor, a ʻoi aku ka maʻalahi o ka hoʻonohonoho ʻana a me ka hoʻohana ʻana; hana ʻia ka chip laminated inductor ma ka hoʻohana ʻana i ka ʻenehana paʻi multi-layer a me ke kaʻina hana laminated.

ʻO nā ʻokoʻa ʻē aʻe: ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka wela o ka SMD laminated inductor ma mua o ka uea ʻeha SMD inductor. ka ʻokoʻa. No ka hōʻuluʻulu ʻana, ʻaʻole hiki i nā inductors laminated SMD ke ʻike i ka uea, a ʻoi aku ka maikaʻi o ka anti-inductance interference, ka hoʻopau ʻana i ka wela, a me ka mālama ʻana i nā wahi i ʻoi aku ka maikaʻi ma mua o ka SMD wire-wound inductors , akā ʻoi aku ka maikaʻi o nā inductors uea-ʻeha i nā ʻōlelo o ke kū'ē ʻana i kēia manawa. koina hana inductance. ʻOi aku ka maikaʻi, a ʻoi aku ka kiʻekiʻe o ka waiwai ESR o ka inductance uea ma mua o ka inductance laminated chip.

Ma mua, ua ʻōlelo mākou e alakaʻi pololei ana nā mea koʻikoʻi magnetic i ka inductance like ʻole o ka inductance winding. ʻOiaʻiʻo, ma kahi o kēia, ʻokoʻa ka hoʻohana ʻana i ka hoʻohana ʻana i ka inductance winding! He ʻokoʻa nā hana like ʻole o nā core magnetic, a me nā ʻano ʻē aʻe. No ka laʻana, kūpono nā inductors ferrite chip no ka hoʻohana ʻana ma ke ʻano he mea hoʻokomo mana, choke coils, a me nā inductors mālama ikehu. ʻO ka inductance wiliwili o ka mea hao pauka koʻikoʻi he mau hiʻohiʻona M ikaika, a ʻoi aku ka maikaʻi o ka hoʻohana ʻana ma ke ʻano he kānana e hōʻemi i ka interference electromagnetic. Aia pū kekahi mau mea hoʻokomo seramika ʻeha i hoʻohana nui ʻia e hoʻokaʻawale i nā hōʻailona AC, kānana a i ʻole hana i nā kaapuni resonant me nā capacitors a me nā mea pale!
