Cov tub ntxhais ferrite ua raws li ib-tig ib hom choke, thiab tuaj yeem ua tau zoo hauv kev txo cov kev ua thiab / lossis hluav taws xob emission los ntawm cable, nrog rau kev tawm tsam. high-frequency pick-up nyob rau hauv lub cable. … Ferrite cores yog qhov zoo tshaj plaws hauv kev muab qhov txo qis ntawm cov suab nrov tsis xav tau siab tshaj 10 MHz.
ferrite core txo suab nrov li cas?
Los ntawm kev xaim xaim los ntawm lub qhov ntawm lub nplhaib, cov xaim xaim thiab cov ferrite core tsim cov kauj (inductor). … Yog li ntawd, lub kauj ua haujlwm raws li lub lim dej qis uas thaiv cov zaus tam sim no, ua kom muaj lub suab nrov nrov.
ferrite hlaws zoo li cas?
Rau cov khoom siv hluav taws xob muaj suab nrov zoo, cov lus qhia tsim yog siv cov hlaws dai ferrite ntawm li 20% ntawm lawv cov ntsuas dc tam sim no. Raws li pom hauv ob qho piv txwv no, qhov inductance ntawm 20% ntawm qhov ntsuas tam sim no poob mus txog 30% rau 6 A hlaws thiab txog li 15% rau 3 A hlaws.
Kuv yuav xaiv tus tub ntxhais ferrite li cas?
Koj yuav tsum xaiv xaiv cov hlaws ferrite thiab choke qhov twg koj tsis xav tau ntau zaus nyob rau hauv nws qhov kev tawm tsam. Yog tias koj mus qis me ntsis lossis siab me ntsis cov hlaws yuav tsis muaj qhov xav tau.
Vim li cas peb thiaj siv ferrite cores?
Hauv electronics, ferrite core yog ib hom hlau nplaum ua los ntawm ferrite uas cov windings ntawm hluav taws xob transformers thiab lwm yam qhov txhab xws liinductors yog tsim. Nws yog siv rau nws cov khoom ntawm siab sib nqus permeability ua ke nrog qis hluav taws xob conductivity(uas pab tiv thaiv eddy tam sim no).
