Umehluko phakathi kwama-inductors obuhlalu obuzibuthe nama-chip multilayer inductors

1. Ama-inductors obuhlalu obuzibuthe nama-SMT laminated inductors?

Ama-inductors angamadivayisi okugcina amandla kanti ubuhlalu obukazibuthe bangamadivayisi okuguqula amandla (ukusetshenziswa). Ama-inductors ama-laminated we-SMT asetshenziswa kakhulu ukucindezela ukuphazamiseka okwenziwa kumasekethe okuhlunga okuphakela amandla. Ubuhlalu kazibuthe busetshenziswa kakhulu kumasekhethi esignali, ikakhulukazi ku-EMI. Ubuhlalu kazibuthe busetshenziselwa ukumunca amasiginali we-UHF. Isibonelo, amanye amasekhethi efrikhwensi yomsakazo, amaluphu akhiywe ngesigaba, amasekhethi e-oscillator namasekhethi enkumbulo yefrikhwensi ephezulu kakhulu (DDR, SDRAM, RAMBUS, njll.) konke kudinga ukungeza ubuhlalu obukazibuthe engxenyeni yokufaka amandla. I-SMD inductor iwuhlobo lwesici sokugcina amandla, esisetshenziswa kumjikelezo we-LC oscillator, isekethe yesihlungi esimaphakathi nesiphansi, njll. Ibanga lemvamisa yohlelo lokusebenza akuvamile ukuba lidlule u-50MHz.

2. Yiziphi izinzuzo zama-magnetic bead inductors ezicini zesekethe?
Ama-inductors obuhlalu kazibuthe asetshenziselwa ukumunca amasiginali wefrikhwensi ephezulu kakhulu, njengamasekhethi efrikhwensi yomsakazo, amaluphu akhiywe ngesigaba, amasekhethi e-oscillator, okuhlanganisa amasekhethi enkumbulo aphakeme kakhulu (DDR SDRAM, RAMBUS, njll.) Lolu hlobo lwesici sokugcina amandla. isetshenziswa kumjikelezo we-LC oscillation, isekethe yesihlungi esimaphakathi nesiphansi, futhi uhla lwemvamisa yohlelo lokusebenza aluvamile ukweqa okungalungile okungu-50MHZ. Uxhumano lwaphansi ngokuvamile lisebenzisa i-inductor, uxhumano lwamandla luphinde lusebenzise i-inductor, kanti ubuhlalu obukazibuthe busetshenziswa kulayini wesignali? Kodwa empeleni, ubuhlalu kazibuthe kufanele futhi bukwazi ukumunca ukuphazamiseka kwe-high-frequency, akunjalo? Futhi inductance ye-inductance ngemuva kwe-high frequency resonance ayikwazi ukudlala indima….
I-Magnetic Bead Inductance
3. Ingcono kangakanani i-chip inductance kune-magnetic bead inductance?

1. I-laminated inductance:

Iphinde ibe nokuvikela okuhle kazibuthe, ukuminyana okuphezulu kwe-sintering, namandla amahle omshini, uma kuqhathaniswa ne-inductance evunguzayo: usayizi omncane, ohambisana ne-miniaturization yesekethe, isekethe kazibuthe evaliwe, ngeke iphazamise izingxenye ezizungezile, futhi ngeke ithinteke. ngezingxenye ezizungezile Kuyasiza ekufakweni okuphezulu kwezingxenye; isakhiwo esihlanganisiwe se-laminated sinokuthembela okuphezulu, ukumelana nokushisa okuhle, ukuthengiselana okuhle, nokuma okuvamile, okulungele ukukhiqizwa kwentaba okuzenzakalelayo. Okubi ukuthi izinga elifanelekayo liphansi, izindleko ziphezulu, i-inductance incane, futhi inani le-Q lincane. Ngokuvamile, i-inductor ye-multilayer ayikwazi ukubona umugqa, i-multilayer inductor inokukhipha ukushisa okuhle, futhi inani le-ESR lincane. Bungakanani ubuhlalu obuzibuthe be-inductor? Ungathintana nathi mayelana nokucaciswa onentshisekelo kukho!

2. Izinzuzo ze-SMD laminated inductors zihlukile kwamanye ama-inductors:
A. Usayizi omncane.
B. I-solderability enhle kakhulu kanye nokumelana ne-solder, ilungele ukugeleza kwe-soldering kanye ne-reflow soldering.
C. Isekhethi evaliwe, akukho ukugxambukela, ifanele ukufakwa kokuminyana okuphezulu.
D. Ukubukeka okungaqondile, okujwayelekile kokukhwezwa kwesichibi okuzenzakalelayo.
