Kodi chip inductor ndi chiyani?Kodi chimagwiritsidwa ntchito chiyani?Ambiri aiwo samamvetsetsa bwino.Mkonzi wa BIG wotsatira adzakupatsani chidziwitso chatsatanetsatane:

　　 Ma inductors a SMD pamwamba amakwera ma inductors amphamvu kwambiri.Ili ndi mawonekedwe a miniaturization, apamwamba kwambiri, kusungirako mphamvu zambiri komanso kukana kochepa.Amagwiritsidwa ntchito makamaka pama board owonetsera apakompyuta, makompyuta apakompyuta, mapulogalamu a pulse memory, ndi otembenuza DC-DC.

　　 Pali mitundu inayi ya ma chip inductors: chip-filimu yopyapyala, yoluka, chilonda chawaya ndi ma inductors ambiri.Mitundu iwiri yamtundu wa mabala a waya ndi mtundu wa laminated amagwiritsidwa ntchito kwambiri.Zakale ndizopangidwa ndi miniaturization ya miyambo yamabala opangira mawaya;chomalizacho chimapangidwa pogwiritsa ntchito ukadaulo wosindikizira wamitundu yambiri ndiukadaulo wopanga laminated.Voliyumu yake ndi yaying'ono kuposa ya ma waya-bala chip inductors.Ndilo chinthu chofunikira kwambiri chomwe chimapangidwa m'munda wa zigawo za inductive.

　　 Thin film chip chip inductors ali ndi mawonekedwe osunga ma Q apamwamba, kulondola kwambiri, kukhazikika kwapamwamba komanso kukula kochepa pama frequency a microwave.Ma elekitirodi amkati amakhazikika pagawo lomwelo, ndipo kugawa kwa maginito kumakhazikika, komwe kumatha kuwonetsetsa kuti magawo a chipangizocho atakwera sasintha kwambiri, ndikuwonetsa mawonekedwe abwino pafupipafupi kuposa 100MHz.

　　Makhalidwe a chip inductors oluka ndikuti voliyumu inductance pa 1MHz ndi yayikulu kuposa ma chip inductors ena, yaying'ono kukula kwake, komanso yosavuta kuyiyika pagawo.Amagwiritsidwa ntchito ngati gawo laling'ono la maginito pakukonza mphamvu.

Makhalidwe a ma waya-bala chip inductors ndi osiyanasiyana inductance (mH～H), kulondola kwakukulu kwa inductance, kutayika kochepa (ndiko kuti, Q yayikulu), yayikulu yovomerezeka, cholowa champhamvu chopanga, kuphweka, komanso mtengo wotsika, koma Choyipa ndichakuti ndizochepa pakuwonjezera pang'ono.Ceramic-core wire-wound chip inductor imatha kukhala ndi inductance yokhazikika komanso mtengo wokwera kwambiri wa Q pama frequency apamwamba chotere, motero imakhala ndi malo ozungulira kwambiri.

　　 Ma inductors owumbika ali ndi zida zabwino zotchingira maginito, kachulukidwe kakang'ono ka sintering, komanso mphamvu zamakina.Zoyipa zake ndi zotsika mtengo, mtengo wokwera, inductance yaying'ono, komanso mtengo wotsika wa Q.Poyerekeza ndi waya chilonda chip inductors, stacking ali ndi ubwino wambiri: yaing'ono kukula, amene amathandiza kuti miniaturization wa dera, chatsekedwa maginito dera, sangasokoneze ozungulira zigawo zikuluzikulu, ndipo sadzakhala kusokonezedwa ndi zigawo zoyandikana, zomwe zimathandiza kuti zigawo zikuluzikulu High. - kachulukidwe unsembe wa zipangizo;kamangidwe kaphatikizidwe, kudalirika kwakukulu;zabwino kutentha kukana ndi solderability;mawonekedwe okhazikika, oyenera kupanga makina oyika pamwamba.
