Ngembobo ye-EMI ferrite bead

Incazelo emfushane:

EMI ferrite bead, futhi ebizwangokusebenzisa i-hole inductor, ukusetshenziswa kwe-ferrite yokulahlekelwa okukhulu,etholakalayokumanani amaningi kanye nezilungiselelo ukuze zivumelane nohlelo lokusebenza oluningi.I-Ferrite bead iwuhlobo lwezinhlelo zokusebenza ezilwa nokujama izingxenye ezikhula ngokushesha, ezishibhile, ezisebenziseka kalula, ezihluza umsindo wemvamisa ephezulu zithuthukiswe kakhulu.Ubuhlalu beFerrite obuvame ukusetshenziswa ekusebeni noma ekunciphiseni umsindo'Uchungechunge lwe-Ferrite Beads RH olunokumelana okuphezulu nokuthembeka.Ubuhlalu be-Ferrite bungasetshenziswa ukucindezela imodi ehlukile yomsindo.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Uhlolojikelele:

I- through inductor isetshenziswa ngokukhethekile ukucindezela umsindo wefrikhwensi ephezulu kanye nokuphazamiseka okuphezulu komugqa wesiginali nolayini wamandla, futhi inamandla okumunca ukushaya kwe-electrostatic.Ubuhlalu kazibuthe busetshenziselwa ukumunca amasiginali we-UHF.Isibonelo, amanye amasekhethi e-RF, i-PLL, amasekhethi e-oscillation kanye namasekhethi enkumbulo ye-UHF (ddrsdram, Rambus, njll.) adinga ukungeza ubuhlalu obukazibuthe engxenyeni yokokufaka kwamandla kagesi.I-Inductor iyingxenye yesitoreji samandla, esetshenziswa kusekethe ye-LC oscillation, isekethe yesihlungi sefrikhwensi emaphakathi nephansi, njll. Ibanga lemvamisa yohlelo lwayo lokusebenza akuvamile ukuba lidlule u-50MHz.Ubuhlalu obuzibuthe bunokumelana okuphezulu nokuqina, okulingana nochungechunge lokuxhunywa kokumelana ne-inductance, kodwa ukumelana ne-inductance kuyahlukahluka ngemvamisa.

Ubuhlalu be-Ferrite bungasetshenziselwa ukuhlunga umsindo wemvamisa ephezulu kumasekhethi wamandla (okukhipha i-DC ne-AC), kodwa futhi busetshenziswe kabanzi kwezinye izifunda, futhi umthamo wabo ungenziwa ube mncane.Ikakhulukazi kumasekhethi edijithali, ngoba isignali ye-pulse iqukethe ama-harmonics aphezulu-frequency, okubuye kube umthombo oyinhloko wemisebe ye-high-frequency kumjikelezo, ingadlala indima yobuhlalu kazibuthe kulesi senzakalo.Ubuhlalu be-Ferrite bubuye busetshenziswe kabanzi Ukuhlunga komsindo kwezintambo zesignali.

Izinzuzo:

1.cindezela umsindo wefrikhwensi ephezulu kanye nokuphazanyiswa okuphezulu komugqa wesiginali nolayini wamandla

2. high resistivity kanye permeability

3. Ukwakhiwa okumazombezombe, izinyathelo zokubala ze-FCC, i-VDE

4. Ukucindezelwa kwe-EMI/RFI

5.Ingakwazi ukwenza ngendlela oyifisayo iumkhiqizongokwesicelo sakho.

Usayizi nobukhulu:

Izakhiwo zikagesi:

Izakhiwo zikagesi:

2-impedance min - (@ 100MHz) 60 Ohms

3-Wire = AWG 33 - Ububanzi 0.18 mm

Qaphela: kubo bonke =μiac ~ 300

Isicelo:

1. Imishini yokuxhumana ngocingo

2. Imishini yokuxhumana engenantambo.

3. Imikhiqizo yekhompyutha

4. Izinhlelo zokusebenza ze-elekthronikhi ezijwayelekile lapho ukucindezelwa kwe-EMI/RFI kuceliwe.
