Xa sikhetha imveliso, ngokuqhelekileyo sikhetha ngokwemiba yangaphandle. Kukwanjalo nakwi-chip inductors. Kufuneka siqwalasele ezinye izinto zangaphandle okanye zangaphakathi ukukhetha i-chip inductor efanelekileyo kuthi, echaphazela i-chip. Zininzi izinto ezibangela inductance

Ukuba imveliso idinga i-inductor ye-chip kunikezelo lwamandla oluphathwayo, ngokuqhelekileyo kufuneka ithathele ingqalelo amanqaku amathathu: ubungakanani, ubungakanani, kunye nenqaku lesithathu kusenobungakanani. Kutheni ugxininisa kubukhulu? Ubungakanani bebhodi yesekethe yeselula incinci ngokwendalo. Izixhobo zanamhlanje eziphathwayo ziquka imisebenzi yangaphambili efana neMP3, MP4, kunye nevidiyo. Imisebenzi emininzi inyuse ukusetyenziswa kwebhetri. Ngoko ke, ukuze kubonelelwe ngezisombululo ezisebenzayo, abaphandi baziphucula kancinane.

Umzekelo, isiguquli se-magnetic buck ngoku sisetyenziselwa ukutshintsha isilawuli somgca ebesisetyenziswa ngaphambili okanye esiqhagamshelwe ngqo kwibhetri.

Ukongeza kubukhulu, iinkcukacha eziphambili ze-inductor kufuneka ziqwalasele ixabiso le-inductance, i-DC impedance ye-coil, i-saturation yangoku, kunye ne-AC impedance ESR. Ngexesha elifanayo, kuxhomekeke kwisicelo, i-inductance ekhuselekileyo kunye ne-inductance engakhuselekanga kufuneka ithathelwe ingqalelo.

Kwakhona kufuneka siqwalasele ukulahlekelwa kwe-inductor phantsi kwamandla e-AC. Utshintsho kwi-inductance phantsi kwe-AC enikwe ngumenzi we-inductor ngamnye yahlukile. I-impedances ye-AC eyahlukeneyo eveliswa ngamaza ahlukeneyo okutshintsha ahlukeneyo, okubangela ukungafani phantsi kwemithwalo ekhanyayo. Kubaluleke kakhulu ukuphucula ubomi bebhetri kwiinkqubo zamandla eziphathekayo.
