Menene SMD inductors? Me ake amfani da su? Yawancinsu tabbas ba a fahimta sosai ba. Editan BIG mai zuwa zai ba ku cikakken gabatarwa:
SMD inductor surface Dutsen high-power inductors. Yana yana da halaye na miniaturization, high quality, high makamashi ajiya da kuma low juriya. Ana amfani da shi a allunan nunin kwamfuta, kwamfutocin littafin rubutu, shirye-shiryen ƙwaƙwalwar ajiyar bugun jini, da masu canza DC-DC.
Akwai nau'ikan inductor na guntu guda 4: guntun fim na bakin ciki, saƙa, raunin waya da inductor multilayer. Nau'in nau'i biyu na nau'in raunin waya da nau'in laminated ana amfani da su akai-akai. Na farko samfur ne na ƙaranci na inductor mai raɗaɗi na gargajiya; Ana yin na ƙarshe ta amfani da fasahar bugu da yawa da kuma fasahar samar da laminated. Ƙararren ƙarami ya fi na inductor guntu rauni na waya. Wani mahimmin samfur da aka haɓaka a fagen abubuwan haɓakawa.
Inductor guntu guntu na sirara-fim suna da halaye na kiyaye babban Q, babban daidaito, babban kwanciyar hankali da ƙaramin girma a cikin mitar mitar microwave. Na'urorin lantarki na ciki suna mayar da hankali a kan Layer guda ɗaya, kuma rarrabawar filin magnetic yana da hankali, wanda zai iya tabbatar da cewa sigogi na na'ura bayan hawan ba su canza da yawa ba, kuma suna nuna halaye masu kyau a sama da 100MHz.
Siffar inductor guntu saƙa ita ce inductance ƙarar naúrar a 1MHz ya fi sauran inductor guntu girma, ƙarami, kuma mai sauƙin girka akan ma'aunin. An yi amfani da shi azaman ƙaramin abin maganadisu don sarrafa wutar lantarki.
Halayen inductor guntu mai rauni na waya sune kewayon inductance (mH～H), daidaiton inductance mai girma, ƙarancin asara (babban Q), babban izini na yanzu, gadon tsarin masana'anta mai ƙarfi, sauƙi, da ƙarancin farashi, amma rashin amfani shine cewa yana da iyaka a cikin ƙarin miniaturization. Nau'in inductor na yumbu mai jujjuyawar nau'in guntu na iya kiyaye inductance mai tsayayye da ƙimar Q daidai gwargwado a irin wannan babban mitar, don haka ya mamaye wuri a cikin babban da'irar.
Inductor da aka tara suna da kyawawan kaddarorin garkuwar maganadisu, daɗaɗɗen ƙima, da ƙarfin injina mai kyau. Rashin lahani shine ƙarancin izinin wucewa, tsada mai tsada, ƙaramin inductance, da ƙarancin ƙimar Q. Idan aka kwatanta da waya rauni guntu inductors, stacking yana da yawa abũbuwan amfãni: kananan size, wanda shi ne conducive zuwa miniaturization na kewaye, rufe Magnetic kewaye, ba zai tsoma baki tare da kewaye aka gyara, kuma ba za a tsoma baki da makwabta aka gyara, wanda yake da amfani ga aka gyara High -yawancin shigarwa na na'urori; tsarin da aka haɗa, babban abin dogara; mai kyau zafi juriya da solderability; na yau da kullum siffar, dace da sarrafa kansa surface hawa samar.
