Uma sikhetha umkhiqizo, sivame ukukhetha ngokuvumelana nezici zangaphandle. Okufanayo kuyiqiniso kuma-chip inductors. Kudingeka sicabangele ezinye izici zangaphandle noma zangaphakathi ukuze sisikhethele i-chip inductor efanelekile, ethinta i-chip. Kunezici eziningi ze-inductance
Uma umkhiqizo udinga i-chip inductor ukuze uthole amandla aphathekayo, ngokuvamile udinga ukucabangela amaphuzu amathathu: usayizi, usayizi, futhi iphuzu lesithathu kusengusayizi. Kungani ugxila kusayizi? Usayizi webhodi lesekhethi yeselula mncane ngokwemvelo. Imishini ephathwayo yanamuhla ihlanganisa imisebenzi yangaphambilini efana ne-MP3, MP4, nevidiyo. Imisebenzi eyengeziwe ikhulise ukusetshenziswa kwebhethri. Ngakho-ke, ukuze kuhlinzekwe izixazululo ezisebenza kahle, abacwaningi bazithuthukisa kancane kancane.
Isibonelo, isiguquli sebhaka kazibuthe manje sisetshenziselwa ukufaka isilawuli somugqa esike sasetshenziswa ngaphambili noma esixhunywe ngokuqondile ebhethrini.
Ngokungeziwe kusayizi, ukucaciswa okuyinhloko kwe-inductor kufanele futhi kucabangele inani le-inductance, i-DC impedance yekhoyili, ukulinganisa kokusebenza kwamanje, kanye ne-AC impedance ESR. Ngesikhathi esifanayo, ngokuya ngesicelo, i-inductance evikelekile kanye ne-inductance engavikelekile kufanele futhi icatshangelwe.
Kudingeka futhi sicabangele ukulahleka kwe-inductor ngaphansi kwamandla e-AC. Izinguquko ku-inductance ngaphansi kwe-AC ezinikezwe umkhiqizi ngamunye we-inductor zihlukile. Ama-impedances ahlukene e-AC akhiqizwa amaza okushintsha ahlukene ahlukile, okuholela ekuhlukeni ngaphansi kwemithwalo ekhanyayo. Kubaluleke kakhulu ukwenza ngcono impilo yebhethri ezinhlelweni zamandla aphathekayo.
