I ka chip common mode inductor , hiki ke koho ʻia nā huahana like ʻole e like me nā ʻano a me nā koi nui. ʻO Gv Electronics, kahi hale hana chip inductor , e kaʻana like me ʻoe pehea e koho ai i ka coil choke mode COMMon pono mai kahi ʻano o ka ʻike.
Pono paha ʻoe i kēia ma mua o kāu kauoha
1. Pehea e hoʻohana ai i ka hoʻoili ʻokoʻa a me nā coils choke mode maʻamau
Ma mua o ka wehewehe ʻana i nā hiʻohiʻona o nā wili kīʻaha maʻamau, e hoʻolauna mua i ka manaʻo o ka hōʻailona mode maʻamau a me ka hōʻailona ʻokoʻa.
ʻO ka hoʻoili ʻokoʻa kahi ʻano i hoʻohana ʻia no ka lawe ʻana i ka ʻikepili kiʻekiʻe. No ka laʻana, MIPI? hoʻohana ʻia i ka pahupaʻikiʻi a me ka pale hōʻikeʻike o nā smartphones, HDMI?, DisplayPort, a me USB o nā kamepiula he mau ʻano hoʻoili like ʻole.
Ma nā laina ʻelua o ka hoʻoili ʻokoʻa ʻana, ʻo ka pae o kekahi i kekahi (e hōʻike ana i ka ʻae ʻana o ka hawewe voli a me ke ʻano nalu o kēia manawa) ua hoʻohuli ʻia ka hoʻouna ʻana i ka hōʻailona.
Ua kapa ʻia kēia hōʻailona he hōʻailona mode differential, a ua hana ʻia ka lawe ʻana i ka ʻikepili ma o ka hōʻailona mode differential. (Ua kapa ʻia ke ʻano ʻokoʻa ma ke ʻano maʻamau). Ke hoʻohālikelike ʻia me nā hōʻailona ʻano ʻokoʻa, aia kekahi hōʻailona i kapa ʻia ka hōʻailona mode maʻamau, i hoʻouna ʻia i ka pae like i nā laina 2.
No ka chip inductor mode maʻamau no nā laina hōʻailona, ʻo ka hōʻailona mode maʻamau he hōʻailona makemake ʻole, ʻo ia hoʻi, ka walaʻau, i kapa ʻia ka leo ʻano maʻamau.
Hoʻohui ʻia nā hōʻailona ʻano ʻokoʻa me ka walaʻau ʻano maʻamau. Ke loaʻa ka hōʻailona ʻokoʻa, hoʻoikaika nā hōʻailona ʻokoʻa kekahi i kekahi, a ʻo ka walaʻau ʻano maʻamau e hoʻopau kekahi i kekahi. ʻAʻole maʻalahi nā ala hoʻoili like ʻole e like me kēia i ka walaʻau ʻano maʻamau.
ʻIke ʻia nā hōʻailona hoʻoheheʻe ʻokoʻa i kahi mamao, a kau ʻia nā hōʻailona ma luna o kekahi. I kēia manawa, hoʻopau nā hōʻailona ʻano ʻokoʻa i kekahi i kekahi, a hoʻoikaika ka walaʻau ʻano maʻamau i kekahi i kekahi. ʻO ia hoʻi, hiki ke maʻalahi i ka walaʻau maʻamau ma kahi mamao.
Ke hiki mai nā pilikia leo like, hoʻopili ʻia ka coil choke mode maʻamau i ka laina hoʻouna ʻokoʻa e wehe pono i ka walaʻau ʻano maʻamau.
2. ʻIke i nā hiʻohiʻona o nā coils choke mode maʻamau
ʻO ka ʻoiaʻiʻo, ua hoʻemi iki ka walaʻau ʻokoʻa ma muli o ke ʻano choke coil maʻamau. Eia kekahi, ʻike nā hōʻailona ʻokoʻa-mode a me nā hōʻailona maʻamau i nā hōʻemi like ʻole ma muli o nā alapine like ʻole. Hōʻike ʻia nā hiʻohiʻona o ia ʻano choke coil maʻamau e nā hiʻohiʻona alapine o ka nalowale o ke ʻano hoʻokomo ʻokoʻa Sdd21 a me ka hōʻailona hoʻokomo ʻano maʻamau Scc21. (ʻO Sdd21 a me Scc21 kekahi ʻāpana o nā ʻāpana S-4-port mode hui pū ʻia)
ʻO nā hiʻohiʻona alapine o ke ʻano maʻamau hoʻokomo nalowale Scc21. ʻOi aku ka hohonu o ka poho hoʻokomo, ʻoi aku ka nui o ka poho. ʻO ke kiʻekiʻe o ke alapine o ka hōʻailona mode differential, ʻoi aku ka nui o ka poho. ʻO ka nalowale o ka hoʻokomo ʻana i ke ʻano maʻamau ʻo Scc21 he pihi me kahi kiʻekiʻe, a ʻokoʻa ka hopena o ka wehe ʻana i ka leo maʻamau ma muli o ke alapine.
ʻO ke alapine hōʻailona o ka chip common mode inductor no ka laina hōʻailona e like me ke ʻano o ka interface, a hoʻololi pū ke ʻano choke coil maʻamau.
Hiki ke hoʻoholo ʻia ke ʻano maʻamau choke coil e like me ke ʻano o ka nalu hōʻailona. ʻO ka maʻamau, ʻo ke alapine ʻoki ʻia o ka coil choke mode maʻamau ʻekolu manawa i ka alapine hōʻailona o ka kikoʻī hoʻouna ʻokoʻa. ʻO ke alapine cutoff i kapa ʻia ʻo ia ka alapine i lilo ai ka poho hoʻokomo ʻokoʻa i 3 dB.
Eia naʻe, ʻoiai inā ʻoi aku ka liʻiliʻi ma mua o 3 mau manawa, nui nā pilikia i ka nalu hōʻailona, a he kuhikuhi kēia i ka maikaʻi loa. (No ka mea, ua kau ʻia ka maʻamau o ka maikaʻi o ka hōʻailona e like me ka palapala perforation ma kēlā me kēia interface, e hoʻoholo hope ʻia inā kūpono a ʻaʻole paha e like me kēia maʻamau)
Ma kekahi ʻaoʻao, ʻokoʻa ka walaʻau pilikia a me kona alapine mai ka terminal a i ka terminal, a no laila ke hoʻololi ʻia nā ʻano alapine o ka poho hoʻokomo maʻamau kūpono.
No ka laʻana, i ka wā i ʻoi aku ai ka walaʻau ma mua o ka waiwai palena i ʻōlelo ʻia e ka maʻamau hoʻoponopono hoʻokuʻu, ʻoi aku ka maikaʻi o ke koho ʻana i ka mea nona ka poho hoʻokomo maʻamau maʻamau i loko o ke alapine o kēlā walaʻau.
Eia kekahi, ʻo ka walaʻau ʻano maʻamau i hōʻike ʻia e ka hoʻouna ʻokoʻa hiki ke hoʻopilikia i kāna mau hana kamaʻilio uila e like me LTE a me Wi-Fi. Hiki ke noʻonoʻo ʻia ʻo ka walaʻau ʻano maʻamau o ke alapine like me ke kamaʻilio uea ʻole, a loaʻa i ka antenna kēia walaʻau. Kapa ʻia kēia ʻo suppressed reception sensitivity. I kēia manawa, ma ka hoʻokomo ʻana i kahi coil choke mode maʻamau, hiki ke hoʻopau ʻia ka hoʻokuʻu ʻana o ka walaʻau ʻano maʻamau a hiki ke hoʻomaikaʻi ʻia ka ʻike hoʻokipa.
ʻO ka mea i luna nei he hoʻolauna i nā hiʻohiʻona o nā inductors mode maʻamau SMD. Inā makemake ʻoe e ʻike hou aku e pili ana i nā inductors SMD, e ʻoluʻolu e kelepona mai iā mākou.
ka hana ʻana i nā ʻano ʻano like ʻole o nā ʻano like ʻole o ke apo kala, nā beaded inductors, vertical inductors, tripod inductors, patch inductors, bar inductors, common mode coils, high-frequency transformers a me nā mea ʻē aʻe.
