Waa maxay SMD inductors? Maxaa loo isticmaalaa? Badankooda hubaal si fiican looma fahmin. Tifaftiraha BIG ee soo socda ayaa ku siin doona hordhac faahfaahsan:
Inductors-ka SMD oogada sare waxay ku dhejiyaan inductors awood sare leh. Waxay leedahay sifooyinka miniaturization, tayada sare leh, kaydinta tamarta sare iyo iska caabin hoose. Inta badan waxaa loo isticmaalaa looxyada bandhiga kombuyuutarka, kombuyuutarrada buug-yaraha, barnaamijyada xusuusta garaaca wadnaha, iyo beddelayaasha DC-DC.
Waxaa jira 4 nooc oo ah inductor chip: chip-filim khafiif ah, tolmo leh, boogo silig ah iyo inductors multilayer. Laba nooc oo ah nooca boogaha siliga ah iyo nooca dahaadhka ah ayaa caadi ahaan la isticmaalaa. Midda hore waa wax-soo-saarka yar-yar ee inductors-nabar-dhaqameedka; kan dambe waxaa lagu sameeyaa iyadoo la adeegsanayo tignoolajiyada daabacaadda lakabyada badan iyo tignoolajiyada wax soo saarka ee la dhejiyay. Mugga ayaa ka yar kan inductors chip-boogaha. Waa badeeco muhiim ah oo lagu horumariyo qaybaha wax-soo-saarka.
Inductors chip chip-ka khafiifka ah waxay leeyihiin sifooyin lagu ilaalinayo Q sare, saxsanaan sare, xasillooni sare iyo cabbir yar oo ku jira guutada soo noqnoqda ee microwave. Electrodes-ka gudaha ah waxay ku urursan yihiin lakab isku mid ah, iyo qaybinta magnetic field qaybinta, taas oo hubin karta in cabbirada qalabka ka dib marka la dhejiyo aysan wax badan isbeddelin, oo muujinaya sifooyinka wanaagsan ee soo noqnoqda ee ka sarreeya 100MHz.
Dabeecadda inductors-ka-xidhka-xidhka ah ayaa ah in inductance mugga unugga ee 1MHz uu ka weyn yahay inductors-ga kale, cabbirkoodu yar yahay, oo ay fududahay in lagu rakibo substrate-ka. Waxa loo istcimaalaa sidii qayb birlabeed yar oo ka shaqaynaysa tamarta
Tilmaamaha inductors chip-boog waa tiro balaadhan oo ah inductance (mH～H), saxnaanta inductance sare, khasaaro hoose (Q weyn), hadda weyn oo la ogolyahay, dhaxalka habka wax soo saarka oo xooggan, fududaan, iyo qiimo jaban, laakiin khasaaraha ayaa ah. in ay ku xaddidan tahay miniaturization dheeraad ah. Inductor nooca dabaysha ah ee dhoobada ah waxa uu ilaalin karaa inductance deggan iyo qiimaha Q si caddaalad ah u sarreeya sida soo noqnoqoshada sare, sidaas darteed waxay ku fadhidaa meel wareegga-soo noqnoqda sare.
Inductors-ka la dulsaaray waxay leeyihiin sifooyin gaashaanka birlabeedka oo wanaagsan, cufnaanta xad-dhaafka ah ee sarreeya, iyo xoog farsamo oo wanaagsan. Khasaarooyinku waa heerka baasas hooseeya, kharash badan, wax-qabad yar, iyo qiimaha Q hooseeya. Marka la barbar dhigo inductors chip boogta silig, isdul-saarku wuxuu leeyahay faa'iidooyin badan: cabbir yar, kaas oo ku habboon miniaturization wareegga, wareegga magnetic xiran, ma faragelin doono qaybaha ku xeeran, mana faragelin doono qaybaha deriska ah, taas oo faa'iido u leh qaybaha Sare -cufnaanta qalabka; qaabdhismeedka isku dhafan, isku halaynta sare; Iska caabbinta kulaylka wanaagsan iyo iibinta; qaab joogto ah, oo ku habboon wax soo saarka korka dusha otomaatigga ah.
