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 inductors saman Dutsen Inductor mai ƙarfi.Yana yana da halaye na miniaturization, high quality, high makamashi ajiya da kuma low juriya.An fi amfani dashi 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;An yi 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 fim na bakin ciki 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 kan Layer guda ɗaya, kuma rarrabawar filin maganadisu yana da hankali, wanda zai iya tabbatar da cewa sigogi na na'ura bayan hawa 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 girma fiye da sauran inductor guntu, ƙarami, kuma mai sauƙin shigarwa a kan madaidaicin.An yi amfani da shi azaman ƙaramin abin maganadisu don sarrafa wutar lantarki.
Halayen inductor guntu mai rauni na waya sune nau'ikan 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 ingantaccen inductance 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.
