Poyerekeza ndi kachulukidwe kakachulukidwe ka maginito, ferrosilicon ndiyokwera kuposa sendust. Komabe, sendust ili ndi maubwino owoneka bwino, omwe amawonekera pakuchulukira kofewa bwino, kutayika kopanda pake, kukhazikika kwa kutentha komanso kutsika mtengo kogwiritsa ntchito. Ma inductors omwe amagwiritsa ntchito ma sendust maginito a ufa amatha kuchotsa zinthu zoyipa zomwe zimachitika chifukwa cha mpweya wa mphete ya ferrite maginito.

zambiri motere:

1. Kuchulukitsitsa kwa maginito B a ferrite ndikochepera kapena kofanana ndi 0.5T, komwe kuli kochepera theka la sendust. Izi zikutanthauza kuti, pansi pa voliyumu yomweyi, kusungirako mphamvu kwa ferrite kumakhala kochepa kwambiri kuposa kutumiza.

2. Kutentha kwa kutentha kwa ferrite ndikotsika kwambiri kuposa kutumiza. Kuchuluka kwa maginito kwa maginito a ferrite kumachepetsedwa kwambiri pansi pa kutentha kwakukulu, pamene maginito a maginito a maginito a maginito othamanga samasintha kwambiri pa kutentha kwakukulu.

3. Ferrite ali ndi makhalidwe ofulumira komanso odzaza. Ngati ipitilira mtengo wotetezedwa, imatha kupangitsa kuti inductance igwe yonse, pomwe Sendust ili ndi mawonekedwe ofewa komanso odzaza ndipo imatha kupirira zikhalidwe zapamwamba zamakono.

4. Sendust cores ndi yoyenera kwambiri kwa inductors zosungiramo zosungira mphamvu posintha magetsi. Poyerekeza ndi mpweya-gap ferrite kapena chitsulo ufa cores wa kukula ndi permeability, sendust cores ndi mkulu flux machulukitsidwe angapereke mphamvu yosungirako apamwamba.

5. Pamene kuli kofunika kudutsa lalikulu kulankhula voteji popanda kupanga zonse phokoso fyuluta inductors, ntchito sendust pachimake akhoza kuchepetsa kukula kwa Intaneti fyuluta. Chifukwa kuchuluka kwa matembenuzidwe ofunikira ndi ocheperako kuposa a ferrite, sendust ilinso ndi magnetostriction coefficient pafupi ndi ziro, ndiko kuti, imakhala chete pakuchita phokoso kapena pa intaneti pamayendedwe omveka.

6.Kuchuluka kwa maginito komanso kutayika kwapakati kumapangitsa kuti ma sendust cores akhale oyenera kwambiri pamagetsi oyendetsa magetsi ndi ma unidirectional drive, monga ma flyback transformers ndi pulse transformers.
