Isekhethi yesihlungi semodi evamile, i-La kanye ne-Lb amakhoyili e-inductance yemodi evamile. Ngale ndlela, lapho i-current evamile kumjikelezo idlula ku-inductance yemodi evamile, izinkambu kazibuthe ezihlehlayo ezikhiqizwa ama-currents kumakhoyili e-inductance alimaza esigabeni esifanayo akhansela. Kulokhu, isignali evamile yamanje ithinteka kakhulu ukumelana nekhoyili. Lapho imodi evamile yamanje Lapho udlula kukhoyili, ngenxa ye-isotropy yemodi evamile yamanje, insimu kazibuthe ohlangothini olufanayo ikhiqizwa ikhoyili, okwandisa ukungeniswa kwekhoyili, futhi kwenza ikhoyili ibonakale njenge-impedance ephezulu. futhi ikhiqiza umphumela onamandla wokudambisa. Ivamise ukusetshenziselwa ukuhlunga amasiginali wokuphazamiseka kagesi wemodi evamile ekushintsheni amandla kagesi. Ukuhlunga kwe-EMI kusetshenziselwa ukucindezela amagagasi kagesi akhiqizwe imigqa yesiginali enesivinini esikhulu ukusuka ekukhanyeni ngaphandle.

Isekhethi yesihlungi semodi evamile, i-La kanye ne-Lb amakhoyili e-inductance yemodi evamile. Amakhoyili amabili alinyazwa enkabeni yensimbi efanayo enenani elifanayo lezibani nezigaba. Ngale ndlela, lapho i-current evamile kumjikelezo idlula ku-inductance yemodi evamile, izinkambu kazibuthe ezihlehlayo ezikhiqizwa ama-currents kumakhoyili e-inductance alimaza esigabeni esifanayo akhansela. Kulokhu, isignali evamile yamanje ithinteka kakhulu ukumelana nekhoyili. Lapho imodi evamile yamanje Lapho udlula kukhoyili, ngenxa ye-isotropy yemodi evamile yamanje, insimu kazibuthe ohlangothini olufanayo ikhiqizwa ikhoyili, okwandisa ukungeniswa kwekhoyili, kwenza ikhoyili ibonakale i-impedance ephezulu, futhi ikhiqiza umphumela onamandla wokudambisa.
Eqinisweni, lapho umkhawulo owodwa wesifunda sokuhlunga uxhunywe emthonjeni wokuphazamiseka, kanti omunye umkhawulo uxhunywe kudivayisi yokuphazamisa, i-La ne-C1, i-Lb ne-C2 yakha amasethi amabili okuhlunga okuphansi, okungalawula umugqa ovamile. Imodi ye-EMI isignali iye ezingeni eliphansi. Lo mjikelezo awukwazi nje ukucindezela ukungena kwamasiginali we-EMI wangaphandle, kodwa futhi unciphise amasiginali e-EMI akhiqizwe umugqa ngokwawo, onganciphisa ngempumelelo ukushuba kokuphazanyiswa kwe-EMI. I-inductor yemodi evamile evamile ekhiqizwa ekhaya, ithatha izinyathelo zokucindezela umsindo wemvamisa ephezulu, ukwakheka kwekhoyili yemodi evamile, akukho ukuncishiswa kwesignali, usayizi omncane, kulula ukuyisebenzisa, ibhalansi enhle, kulula ukuyisebenzisa, ikhwalithi ephezulu kanye nezinye izinzuzo. Isetshenziswa kabanzi kumadivayisi wokushuna alinganiswe kabili, ama-multi-frequency transformers, ama-impedance transformer, ama-transformer alinganiselayo nangalingani, njll.
I-inductor yemodi evamile isho ukuthi amakhoyili amabili alinyazwe kumongo wensimbi ofanayo, ama-winding aphambene, inani lokujika nesigaba kuyefana. Ivamise ukusetshenziselwa ukuhlunga amasiginali wokuphazamiseka kagesi wemodi evamile ekushintsheni amandla kagesi. Ukuhlunga kwe-EMI kusetshenziselwa ukucindezela amagagasi kagesi akhiqizwe imigqa yesiginali enesivinini esikhulu ukusuka ekukhanyeni ngaphandle.
