BIG imauza aliyense: Ma chip inductors, omwe amadziwikanso kuti ma inductors amphamvu, ma inductors apamwamba kwambiri komanso ma inductors okwera kwambiri. Ili ndi mawonekedwe a miniaturization, apamwamba kwambiri, kusungirako mphamvu zambiri komanso kukana kochepa. Pali mitundu iwiri ya magetsi chip inductors: okhala ndi chivundikiro cha maginito komanso opanda chivundikiro cha maginito, makamaka opangidwa ndi maginito pachimake ndi waya wamkuwa. Imagwira makamaka ntchito yosefera ndi kusuntha mozungulira.
Nthawi zambiri, ma inductors mumayendedwe apakompyuta ndi ma coil apakati kapena ma coil okhala ndi maginito, omwe amatha kungodutsa mafunde ang'onoang'ono ndikupirira ma voltages otsika; ndi ma inductors amagetsi alinso ndi ma coils a air-core ndi maginito cores. Chofunikira chachikulu ndi Mawaya a Thick amatha kupirira makumi a ma amperes, mazana, masauzande, kapena makumi masauzande a ma amperes.
Ma chip inductors amakhala ndi mitundu 4, yomwe ndi chilonda cha waya, laminated, lolukidwa komanso lopyapyala la chip inductors. 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 ndi ukadaulo wosindikiza wa multilayer 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.
Mtundu wokhotakhota: Umadziwika ndi mitundu yosiyanasiyana ya inductance (mH～H), kulondola kwakukulu kwa inductance, kutayika kochepa (ndiko, Q yayikulu), yayikulu yololeka, cholowa champhamvu, chosavuta, chotsika mtengo, ndi zina zambiri, koma ndizosakwanira Zimaletsedwa mu miniaturization yowonjezera. 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.
Mtundu wa laminated: Ili ndi chitetezo chabwino cha maginito, kachulukidwe kakang'ono ka sintered, komanso mphamvu zamakina. Zoyipa zake ndi zotsika mtengo, mtengo wokwera, inductance yaying'ono, komanso mtengo wotsika wa Q. Poyerekeza ndi waya chilonda chip inductors, ili ndi ubwino wambiri: kukula kwazing'ono, zomwe zimathandiza kuti miniaturization ya dera, yotsekedwa maginito, sichidzasokoneza zigawo zozungulira, ndipo sichidzasokonezedwa ndi zigawo zoyandikana nazo, zomwe zimapindulitsa zigawo Zapamwamba. - kachulukidwe unsembe; kamangidwe kaphatikizidwe, kudalirika kwakukulu; zabwino kutentha kukana ndi solderability; mawonekedwe okhazikika, oyenera kupanga zodziwikiratu padziko lapansi.
Mtundu wa chip filimu: Ili 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.
Mtundu woluka: Mawonekedwe ake ndikuti inductance pa voliyumu iliyonse pa 1MHz ndi yayikulu kuposa ma chip inductors ena, yaying'ono kukula kwake, komanso yosavuta kuyiyika pagawo lapansi. Amagwiritsidwa ntchito ngati gawo laling'ono la maginito pakukonza mphamvu.
Ma inductors a SMD makamaka amakhala ndi mitundu iyi pamwambapa. Ngati mukufuna kudziwa zambiri zamalonda okhudzana ndi ma chip inductors, chonde pitilizani kulabadira zosintha zatsambali, kapena funsani kukambirana ndi kugula.
