Kodi ma inductors a SMD ndi chiyani? Amagwiritsidwa 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 Q apamwamba, kulondola kwambiri, kukhazikika kwapamwamba komanso kukula kochepa mu bandi ya ma frequency a microwave. Ma maelekitirodi amkati amakhazikika pagawo lomwelo, ndipo kugawa kwa maginito kumakhazikika, komwe kungatsimikizire 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-wound chip inductors ndi mitundu yosiyanasiyana ya inductance (mH～H), kulondola kwambiri kwa inductance, kutayika kochepa (yaikulu Q), kuvomerezeka kwakukulu kwaposachedwa, cholowa champhamvu chopanga cholowa, kuphweka, komanso mtengo wotsika, koma Choyipa ndi kuti ndi zochepa mu miniaturization zina. Ceramic core winding type chip inductor imatha kukhala ndi inductance yokhazikika komanso mtengo wokwera kwambiri wa Q pama frequency oterowo, 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: kukula kakang'ono, 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.
