ʻO ka ʻokoʻa ma waena o nā inductors magnetic bead a me nā chip multilayer inductors

1. Magnetic bead inductors a me SMT laminated inductors?

ʻO nā Inductors nā mea mālama ikehu a ʻo nā peʻa magnetic nā mea hoʻololi ikehu (hoʻohana).Hoʻohana nui ʻia nā inductors laminated SMT e kāohi i ka hoʻopili ʻia i nā kaʻa kānana lako mana.Hoʻohana nui ʻia nā peʻa Magnetic i nā kaapuni hōʻailona, ​​no ka EMI.Hoʻohana ʻia nā peʻa magnetic e hoʻopaʻa i nā hōʻailona UHF.No ka laʻana, ʻo kekahi mau kaapuni alapine lekiō, nā puka lou i hoʻopaʻa ʻia, nā kaapuni oscillator a me nā kaʻa hoʻomanaʻo hoʻomanaʻo kiʻekiʻe kiʻekiʻe (DDR, SDRAM, RAMBUS, a me nā mea ʻē aʻe) pono nā mea a pau e hoʻohui i nā lei magnetic i ka ʻāpana hoʻokomo mana.ʻO ka SMD inductor kahi ʻano mea e mālama ai i ka ikehu, i hoʻohana ʻia i ka LC oscillator circuit, medium and low frequency filter circuit, a me nā mea ʻē aʻe.

2. He aha nā mea maikaʻi o nā mea hoʻoheheʻe magnetic i nā ʻano kaapuni?
Hoʻohana ʻia nā mea hoʻokomo ʻana i nā leki uila no ka hoʻomoʻa ʻana i nā hōʻailona alapine ultra-kiʻekiʻe, e like me kekahi mau kaapuni lekiō, nā puka lou i hoʻopaʻa ʻia, nā kaʻa oscillator, me nā kaapuni hoʻomanaʻo ultra-high frequency (DDR SDRAM, RAMBUS, etc.) ʻO kēia ʻano mea mālama ikehu. hoʻohana ʻia i ka LC oscillation circuit, medium and low frequency filter circuit, a ʻaʻole i ʻoi aku ka nui o kāna noi i ka 50MHZ hewa.Hoʻohana maʻamau ka pili honua i kahi inductor, hoʻohana pū ka pilina mana i kahi inductor, a hoʻohana ʻia kahi lei magnetic ma ka laina hōʻailona?Akā ʻo ka mea ʻoiaʻiʻo, pono e hiki i nā lei magnetic ke komo i ka hoʻopili alapine kiʻekiʻe, ʻeā?A ʻo ka inductance o ka inductance ma hope o ka resonance kiʻekiʻe ʻaʻole hiki ke pāʻani i kahi kuleana….
ʻO ka hoʻokomo ʻana i ka Magnetic Bead Inductance
3. Pehea ka ʻoi aku o ka maikaʻi o ka inductance chip ma mua o ka inductance bead magnetic?

1. Laminated inductance:

Loaʻa iā ia ka pale magnetic maikaʻi, kiʻekiʻe sintering density, a me ka ikaika mechanical maikaʻi, ke hoʻohālikelike ʻia me ka inductance wiliwili: ka liʻiliʻi liʻiliʻi, ka mea e kūpono i ka miniaturization o ke kaapuni, pani ʻia ka magnetic circuit, ʻaʻole e hoʻopilikia i nā ʻāpana a puni, ʻaʻole e hoʻopilikia ʻia. e nā mea hoʻopuni a puni He mea kūpono ia i ka hoʻokomo kiʻekiʻe o nā mea;ʻO ka laminated integrated structure he hilinaʻi kiʻekiʻe, kūpaʻa wela maikaʻi, solderability maikaʻi, a me ke ʻano maʻamau, kūpono no ka hana ʻana i ka mauna ʻili.ʻO ka hemahema ʻo ia ka haʻahaʻa haʻahaʻa kūpono, kiʻekiʻe ke kumukūʻai, liʻiliʻi ka inductance, a liʻiliʻi ka waiwai Q.ʻO ka mea maʻamau, ʻaʻole hiki i ka multilayer inductor ke ʻike i ka laina, ʻo ka multilayer inductor he maikaʻi ka wela wela, a ʻoi aku ka liʻiliʻi o ka waiwai ESR.Pehea ka nui o ka inductor magnetic beads?Hiki iā ʻoe ke nīnau iā mākou e pili ana i nā kikoʻī āu e makemake ai!

2. ʻOkoʻa nā mea maikaʻi o nā inductors laminated SMD mai nā inductors ʻē aʻe:
A. Ka nui liʻiliʻi.
B. ʻOi aku ka maikaʻi o ka solderability a me ke kūpaʻa kūʻai, kūpono no ka hoʻoheheʻe ʻana a me ka reflow soldering.
C. Paʻa kaapuni, ʻaʻohe hoʻopilikia i kekahi, kūpono no ka hoʻokomo ʻana i ke kiʻekiʻe.
D. Non-directional, standardized hiʻohiʻona no ka hoʻouka ʻana i ka ʻakomi.
