ʻO ke ʻano pōʻai a me ke kaula hoʻohui e hana i kahi inductor (ua hoʻohana ʻia ke kaula a puni ke apo magnetic ma ke ʻano he inductance coil), i hoʻohana pinepine ʻia i nā ʻāpana anti-interference o nā uila uila a loaʻa ka hopena pale maikaʻi i ka leo kiʻekiʻe. kapa ʻia ʻo ia he keleawe hoʻoheheʻe, no ka mea, hoʻohana pinepine ʻia ka hao ʻo Ferrite mea, e kamaʻilio e pili ana i nā ferrite beads (ma hope aku i kapa ʻia ʻo nā beads poepoe). ʻO ka luna o ke kiʻi he apo magnetic i hoʻohui ʻia, a ʻo ka lalo he apo magnetic me nā kiʻi e kau ana. Loaʻa i ke apo magnetic nā ʻano impedance ʻokoʻa ma nā alapine like ʻole. ʻO ka maʻamau, liʻiliʻi loa ka impedance i nā alapine haʻahaʻa. Ke piʻi ka alapine hōʻailona, ​​piʻi nui ka impedance o ke apo magnetic. ʻIke ʻia ka maikaʻi o ka inductance. ʻO ke kiʻekiʻe o ke alapine hōʻailona, ​​ʻoi aku ka maʻalahi o ka hoʻomālamalama. ʻO ka mea maʻamau, ʻaʻohe papa pale i ke kaapuni, a hiki i ka antenna me ka hōʻailona maikaʻi ke loaʻa i nā hōʻailona kiʻekiʻe kiʻekiʻe clutter mai ke kaiapuni a puni. Hoʻololi i ka hoʻouna ʻana i nā hōʻailona pono a hoʻopilikia nui i ka hana maʻamau o nā mea uila, no laila pono e hoʻemi ʻia ka interference electromagnetic (EM) o nā mea uila. Ma lalo o ka hana a ke apo magnetic, ʻoiai inā e holo mālie ka hōʻailona pono maʻamau, hiki ke hoʻopaʻa maikaʻi ʻia ka hōʻailona interference kiʻekiʻe, a haʻahaʻa ke kumukūʻai. Inductance apo kala

He kuleana koʻikoʻi nō hoʻi ka inductance i ka pale ʻana i ka hōʻailona, ​​​​ke kānana ʻana i ka walaʻau, ka hoʻopaʻa ʻana i kēia manawa a me ka hoʻopaʻa ʻana i ka electromagnetic interference suppression.

1. Ka hoʻokaʻawale ʻana o ka inductance:

Hoʻokaʻawale ʻia e ka pinepine hana

Hiki ke hoʻokaʻawale ʻia nā inductors i nā inductors kiʻekiʻe, nā inductors intermediate-frequency a me nā inductors haʻahaʻa haʻahaʻa e like me kā lākou hana pinepine.

ʻO ka ea-core, magnetic-core a me ka copper-core inductors ka mea maʻamau i ka medium-frequency a i ʻole ke kiʻekiʻe-frequency inductors, aʻo ka hao-core inductors ka hapa nui o nā inductors haʻahaʻa.
