Ngembobo ye-EMI ferrite bead
Uhlolojikelele:
I-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 lokuxhunyaniswa 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.
