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 ugesi ophathwayo, 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 semali kazibuthe manje sesisetshenziselwa 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.
