Phapang lipakeng tsa li-inductors tsa lifaha tsa makenete le li-inductors tsa chip multilayer

1. Magnetic bead inductors le SMT laminated inductors?

Li-inductors ke lisebelisoa tsa ho boloka matla 'me lifaha tsa makenete ke lisebelisoa tsa ho fetola matla (tšebeliso). Li-inductors tsa laminated tsa SMT li sebelisoa haholo ho hatella tšitiso e etsoang ho li-circuits tsa phepelo ea motlakase. Lifaha tsa makenete li sebelisoa haholo lipotolohong tsa matšoao, haholo bakeng sa EMI. Lifaha tsa makenete li sebelisoa ho monya matšoao a UHF. Ka mohlala, li-circuits tse ling tsa maqhubu a seea-le-moea, li-loops tse notletsoeng ka mekhahlelo, li-circuits tsa oscillator le li-circuits tsa memori tsa ultra-high (DDR, SDRAM, RAMBUS, joalo-joalo) kaofela li hloka ho kenya lifaha tsa makenete karolong ea ho kenya matla. SMD inductor ke mofuta oa matla a ho boloka matla, a sebelisoang ho LC oscillator circuit, medium and low frequency filter circuit, joalo-joalo. Marang-rang a ts'ebeliso ea eona ha a fete 50MHz ka seoelo.

2. Melemo ea li-inductors tsa magnetic bead ka litšobotsi tsa potoloho ke efe?
Li-inductors tsa "magnetic beads inductors" li sebelisoa ho monya mats'oao a maqhubu a phahameng haholo, joalo ka li-circuits tse ling tsa radio frequency, loops tse notletsoeng ka mekhahlelo, li-circuits tsa oscillator, ho kenyeletsoa li-circuits tsa memori tse phahameng haholo (DDR SDRAM, RAMBUS, jj.) Mofuta ona oa polokelo ea matla. e sebelisoa ho LC oscillation circuit, medium and low frequency filter circuit, 'me palo ea maqhubu a ts'ebeliso ea eona ha se hangata e fetang 50MHZ e fosahetseng. Khokahano ea fatše hangata e sebelisa inductor, khokahanyo ea matla e boetse e sebelisa inductor, 'me sefaha sa makenete se sebelisoa moleng oa matšoao? Empa ha e le hantle, lifaha tsa makenete le tsona li lokela ho khona ho monya tšitiso ea maqhubu a holimo, na ha ho joalo? 'Me inductance ea inductance ka mor'a hore resonance e phahameng ea maqhubu a se ke a bapala karolo….
Magnetic Bead Inductance
3. The chip inductance e molemo hakae ho feta magnetic bead inductance?

1. Laminated inductance:

E boetse e na le tšireletso e ntle ea makenete, boima bo phahameng ba sintering, le matla a matle a mochini, ha a bapisoa le inductance ea moea: boholo bo nyane, bo loketseng ho miniaturization ea potoloho, potoloho ea makenete e koetsoeng, e ke ke ea kena-kenana le likarolo tse potolohileng, 'me e ke ke ea ameha. ka likarolo tse pota-potileng E loketse ho kenngoa ha likarolo tse phahameng; mohaho o kopantsoeng oa laminated o na le ts'epo e phahameng, ho hanyetsa mocheso o motle, solderability e ntle, le sebopeho se tloaelehileng, se loketseng bakeng sa tlhahiso ea lihlahisoa tsa holim'a metsi. Phoso ke hore sekhahla se tšoanelehang se tlase, litšenyehelo li phahame, inductance e nyane, 'me boleng ba Q bo nyane. Ka kakaretso, inductor ea multilayer e ke ke ea bona mohala, mochine oa li-multilayer o na le mocheso o motle oa mocheso, 'me boleng ba ESR bo nyenyane. Lifaha tsa makenete tsa inductor li bokae? U ka ikopanya le rona mabapi le litlhaloso tseo u li ratang!

2. Melemo ea SMD laminated inductors e fapane le li-inductors tse ling:
A. Nyenyane.
B. Ho ba le solderability e ntle haholo le ho hanyetsa solder, ho loketse bakeng sa ho phalla ha metsi le ho hlahisa lihlahisoa.
C. Potoloho e koetsoeng, ha ho na tšitiso e kopanetsoeng, e loketseng bakeng sa ho kenya lisebelisoa tse phahameng.
D. Ponahalo e sa tsitsang, e emeng bakeng sa ho kenya patch e iketsang.
