Kudzera dzenje EMI ferrite mkanda

The through inductor imagwiritsidwa ntchito mwapadera kupondereza phokoso lambiri komanso kusokoneza kwambiri kwa mzere wamawu ndi chingwe chamagetsi, komanso imatha kuyamwa ma electrostatic pulse. Mikanda yamaginito imagwiritsidwa ntchito kuyamwa ma siginecha a UHF. Mwachitsanzo, ma circuit ena a RF, PLL, oscillation circuits ndi UHF memory circuits (ddrsdram, Rambus, etc.) amafunika kuwonjezera mikanda ya maginito mu gawo lothandizira la magetsi. Inductor ndi chinthu chosungira mphamvu, chomwe chimagwiritsidwa ntchito mu LC oscillation circuit, sing'anga ndi otsika pafupipafupi fyuluta dera, etc. ake ntchito pafupipafupi osiyanasiyana kawirikawiri kuposa 50MHz. Mikanda ya maginito imakhala ndi resistivity yapamwamba komanso permeability, yomwe ili yofanana ndi mndandanda wa kukana ndi inductance, koma kukana ndi inductance zimasiyana pafupipafupi.

Mikanda ya Ferrite ingagwiritsidwe ntchito osati kungosefa phokoso lafupipafupi m'mabwalo amagetsi (pazotulutsa za DC ndi AC), komanso kugwiritsidwa ntchito kwambiri m'mabwalo ena, ndipo voliyumu yawo imatha kukhala yaying'ono. Makamaka m'mabwalo a digito, chifukwa chizindikiro cha pulse chimakhala ndi ma harmonics apamwamba kwambiri, omwenso ndi gwero lalikulu la ma radiation othamanga kwambiri m'derali, amatha kugwira ntchito ya mikanda ya maginito panthawiyi. Mikanda ya ferrite imagwiritsidwanso ntchito kwambiri Kusefa kwa phokoso la zingwe zama sigino.
