Site oghere EMI ferrite bead
Nchịkọta:
A na-eji site na inductor pụrụ iche na-egbochi mkpọtụ ụda ugboro ugboro na nnyonye anya kacha elu nke ahịrị mgbama na ahịrị ọkụ, ma nweekwa ikike ịmịnye usu electrostatic. A na-eji bead magnetik amịkọrọ akara UHF. Dịka ọmụmaatụ, ụfọdụ sekit RF, PLL, sekit oscillation na sekit ebe nchekwa UHF (ddrsdram, Rambus, wdg) kwesịrị ịgbakwunye bead magnet na akụkụ ntinye nke ọkụ. Inductor bụ ihe nchekwa ike, nke a na-eji na sekit oscillation LC, sekit nzacha ọkara na nke dị ala, wdg. ngwa ngwa ya anaghị adịkarị karịa 50MHz. Mpempe ndọta nwere nnukwu ihe mgbochi na ikike, nke dabara na njikọ nke nguzogide na inductance, mana nguzogide na inductance dịgasị iche na ugboro ole.
Enwere ike iji bead ferrite ọ bụghị naanị iji nyochaa ụda mkpọtụ dị elu na sekit ike (maka mmepụta DC na AC), kamakwa a ga-eji ya mee ihe na sekit ndị ọzọ, enwere ike ime ka olu ha dị ntakịrị. Karịsịa na sekit dijitalụ, n'ihi na mgbaàmà pulse nwere harmonics dị elu, nke bụkwa isi iyi nke radieshon dị elu na sekit, ọ nwere ike ịrụ ọrụ nke bead magnetik n'oge a. A na-ejikwa chaịlị ferrite eme ihe nzacha nke eriri mgbaama.
Uru:
1.kpachie mkpọtụ mkpọtụ ugboro ugboro yana nnyonye anya kacha elu nke ahịrị mgbama na ahịrị ọkụ
2. elu resistivity na permeability
3. Ihe owuwu siri ike, ihe mgbochi maka FCC, VDE
4. Mbelata EMI/RF
5.nwere ike hazie ihengwaahịadị ka arịrịọ gị si dị.
