Ma inductors ndi zigawo zomwe zimatha kusintha mphamvu zamagetsi kukhala maginito mphamvu ndikuzisunga. Ma inductors ndi ofanana m'mapangidwe ndi ma transformer, koma amakhala ndi chopindika chimodzi chokha. Inductor ali ndi inductance inayake, yomwe imalepheretsa kusintha kwamakono. Pomaliza, mafoni a m'manja a 5G amasinthidwa ndikusinthidwa, kubweretsa m'malo mwake, ndipo kufunikira kwa ma inductors kukukulirakulira.

Malingaliro a Inductor

Ma inductors ndi zigawo zomwe zimatha kusintha mphamvu zamagetsi kukhala maginito mphamvu ndikuzisunga. Ma inductors ndi ofanana m'mapangidwe ndi ma transformer, koma amakhala ndi chopindika chimodzi chokha. Ma inductors ali ndi inductance inayake, yomwe imalepheretsa kusintha kwapano. Ngati inductor ili m'malo omwe palibe madzi akuyenda, idzayesa kutsekereza madzi omwe akudutsamo pamene dera likugwirizanitsidwa. Ngati inductor ili m'mayendedwe apano, idzayesa kusunga nthawiyo yosasinthika pamene dera likuchotsedwa.

Ma inductors amatchedwanso chokes, reactors ndi ma reactors amphamvu. Inductor nthawi zambiri imakhala ndi chimango, mapindikidwe, chivundikiro chotchinga, zoyikapo, maginito pachimake kapena chitsulo pakati, ndi zina zotere. Inductance ndi chiŵerengero cha maginito akuyenda kwa kondakitala mpaka pano kutulutsa kusinthasintha kwa maginito mozungulira kokondeka pamene kondakita akudutsa. pompopompo.

Pamene DC yamakono ikuyenda kupyolera mu inductor, mzere wokhazikika wa maginito wa mphamvu umawonekera mozungulira, zomwe sizisintha ndi nthawi. Komabe, mphamvu ya maginito ikadutsa pa koyilo, mizere ya maginito yozungulira imasintha pakapita nthawi. Malingana ndi lamulo la Faraday la electromagnetic induction - magnetism imapanga magetsi, mizere ya maginito yosinthika idzatulutsa mphamvu zogwiritsira ntchito kumapeto kwa coil, zomwe ziri zofanana ndi "gwero lamphamvu latsopano".

Ma inductors amagawidwa kukhala ma inductors ndi ma inductors ogwirizana. Pamene koyiloyo ilipo, maginito amapangidwa mozungulira koyiloyo.

Pamene panopa mu koyilo ikusintha, mphamvu ya maginito yozungulira izo idzasinthanso moyenera. Maginito osinthikawa amatha kupanga koyiloyo yokha kupanga mphamvu ya electromotive (induced electromotive force) (mphamvu ya electromotive imagwiritsidwa ntchito kuyimira mphamvu yamagetsi yamagetsi oyenera a chinthu chogwira), chomwe chimatchedwa kudzilowetsa.

Pamene ma coil awiri a inductance ali pafupi wina ndi mzake, kusintha kwa maginito kwa coil imodzi ya inductance kudzakhudza coil inductance, yomwe imatchedwa mutual inductance. Kukula kwa mutual inductor kumatengera kuchuluka kwa kulumikizana pakati pa inductance ya inductance coil ndi ma coil awiri a inductance. Zigawo zopangidwa pogwiritsa ntchito mfundoyi zimatchedwa mutual inductor.

Kukula kwa msika wamakampani a inductor

Ma chip inductors amagawidwa ndi mawonekedwe a inductor. Malinga ndi gulu la mapangidwe ndi kupanga, ma inductors amagawidwa m'magulu awiri: plug-in olimba inductors ndi chip wokwera inductors. Ukadaulo waukulu wopangira ma inductors amtundu wa plug-in ndi "kuzungulira", ndiye kuti, kondakitala amavulazidwa pachimake cha maginito kuti apange coil inductive (yomwe imadziwikanso kuti coil yopanda kanthu).

Inductor iyi imadziwika ndi mitundu yosiyanasiyana ya inductance, kulondola kwakukulu kwa mtengo wa inductance, mphamvu yayikulu, kutayika pang'ono, kupanga kosavuta, kachitidwe kakang'ono kopanga, komanso kukwanira kwazinthu zopangira. Zoyipa zake ndi kutsika kwapang'onopang'ono kwa kupanga zokha, mtengo wokwera kwambiri, komanso kuvutikira kwa miniaturization ndi kupepuka.

China Electronics Industry Association ikuyerekeza kuti msika wapadziko lonse lapansi udzakula ndi 7.5% pachaka m'zaka zingapo zikubwerazi, China ndiyogula kwambiri zida zopangira zida. Ndi kusintha kofulumira kwaukadaulo waku China wolumikizirana komanso kumanga kwakukulu kwa intaneti ya Zinthu, mizinda yanzeru ndi mafakitale ena ofananira, msika waku China chip inductor udzakula mwachangu kuposa kukula kwapadziko lonse lapansi. Ngati kukula ndi 10%, kukula kwa msika wamakampani a chip inductor kupitilira yuan biliyoni 18. Malinga ndi deta, kukula kwa msika wa inductor padziko lonse lapansi mu 2019 kunali yuan 48.64 biliyoni, kukwera ndi 0.1% chaka ndi chaka kuchokera ku 48.16 biliyoni mu 2018; Mu 2020, chifukwa chakukhudzidwa kwa COVID-19 yapadziko lonse lapansi, kukula kwa msika wama inductors kudzatsika mpaka 44.54 biliyoni. Kukula kwa msika waku China inductor kukuwonetsa kukula. Mu 2019, kukula kwa msika wa inductor waku China kunali pafupifupi RMB 16.04 biliyoni, kuchuluka kwa 13% poyerekeza ndi RMB 14.19 biliyoni mu 2018. mu 2019.

Zikuyembekezeka kuti kufunikira kwa msika kwa ma inductors kudzakulirakulira, ndipo msika wapakhomo udzakhala wokulirapo. Mu 2019, China idatumiza ma inductors 73.378 biliyoni ndikutumiza kunja 178.983 biliyoni, kuchulukitsa 2.4 kuchuluka kwa kunja.

Mu 2019, mtengo wogulitsa kunja kwa ma inductors aku China unali US $ 2.898 biliyoni ndipo mtengo wake unali US $ 2.752 biliyoni.

Makampani opanga zamagetsi ku China asintha kwambiri kuchoka pakupanga magawo otsika mtengo, OEM yamitundu yakunja mpaka kulowa kwa maulalo apamwamba owonjezera, ndipo zogulitsa zapakhomo zakhala zotsogola padziko lonse lapansi. Pakalipano, kupanga mafoni a ku China kumapanga 70% kapena 80% ya dziko lonse lapansi, ndipo mabizinesi aku China akulamulira magawo apakati ndi amtsogolo a makampani opanga zamagetsi padziko lonse lapansi, msonkhano ndi magawo ena, Choncho, mogwirizana ndi mafakitale a "galimoto ngati foni yaikulu ya m'manja” ndi maziko kuti ogula zamagetsi makampani unyolo mabizinezi atumiza m'munda wa magalimoto anzeru, chiyembekezo cha unyolo zoweta ogula zamagetsi makampani m'tsogolo ndi ofunika tikuyembekezera.

Kuwonjezeka kwa chiwerengero cha 5G ma frequency band foni yam'manja kwalimbikitsa kwambiri kugwiritsa ntchito ma unit unit inductors. Ma inductors apamwamba kwambiri padziko lonse lapansi akuyang'anizana ndi kusiyana kwakukulu kwa mphamvu komanso kupezeka kolimba. Mwachidule, kusinthidwa kwa mafoni a m'manja a 5G kunayambitsa njira yosinthira. Kufunika kwa inductance kunapitilira kuwonjezeka. Mliriwu unapangitsa kuti zimphona zina za inductance zichoke. Zosankha zapakhomo zinatsegula malo.
