Farqiga u dhexeeya inductors bead magnetic iyo chip multilayer inductors

1. Inductors bead magnetic iyo SMT laminated inductors?

Inductors waa aaladaha kaydinta tamarta iyo birta birlabku waa aaladaha beddelka tamarta (consumption). Inductors SMT laminated ayaa inta badan loo isticmaalaa si loo xakameeyo faragelinta la sameeyay ee wareegyada shaandhada sahayda korontada. Kuul magnetic inta badan waxaa loo isticmaalaa wareegyada calaamadaha, badiyaa loogu talagalay EMI. Kuul magnetic waxaa loo isticmaalaa in lagu nuugo calaamadaha UHF. Tusaale ahaan, qaar ka mid ah wareegyada soo noqnoqda raadiyaha, wareegyada wajiga xiran, wareegyada oscillator-ka iyo wareegyada xusuusta soo noqnoqda ee aadka u sarreeya (DDR, SDRAM, RAMBUS, iwm.) dhamaantood waxay u baahan yihiin inay ku daraan kuul birlab ah qaybta gelinta tamarta. Inductor SMD waa nooc ka mid ah walxaha kaydinta tamarta, kaas oo loo isticmaalo wareegga LC oscillator, wareegga shaandhada dhexdhexaadka ah iyo mid hooseeya, iwm

2. Waa maxay faa'iidooyinka inductors bead magnetic ee sifooyinka wareegga?
Inductors kuul magnetic waxaa loo isticmaalaa in lagu nuugo calaamadaha soo noqnoqda ultra-sare, sida qaar ka mid ah wareegyada soo noqnoqda raadiyaha, wejiga quful wareegyada, oscillator wareegyada, oo ay ku jiraan ultra-high soo noqnoqda xusuusta wareegyada (DDR SDRAM, RAMBUS, iwm) Noocan ah element kaydinta tamarta waxaa loo isticmaalaa wareegga oscillation LC, wareegga shaandhada dhexdhexaadka ah iyo mid hooseeya, iyo inta jeer ee codsigeeda marar dhif ah ayuu dhaafaa 50MHZ khaldan. Isku xirka dhulka guud ahaan wuxuu isticmaalaa inductor, xiriirka korontadu wuxuu sidoo kale isticmaalaa inductor, iyo bir birlab ah ayaa loo isticmaalaa xariiqda calaamadda? Laakiin dhab ahaantii, kuul magnetic waa inay sidoo kale awoodaan inay nuugaan faragelinta sare ee soo noqnoqda, sax? Iyo inductance of inductance ka dib resonance soo noqnoqda sare ma ciyaari karo door….
Inductance Bead Magnetic
3. Intee in le'eg ayaa ka-soo-baxa-inductance-ku ka fiican yahay inductance-ka bir-labeedka?

1. Inductance Laminated:

Waxa kale oo ay leedahay gaashaan magnetic wanaagsan, cufnaanta sintering sare, iyo xoog farsamo wanaagsan, marka la barbar dhigo inductance dabaylaha: size yar, kaas oo ku habboon miniaturization ee wareegga, wareegga magnetic xiran, ma faragelin doono qaybaha ku xeeran, oo aan la saameyn doono. by qaybaha ku xeeran Waxay ku habboon tahay rakibidda cufnaanta sare ee qaybaha; qaab dhismeedka isku dhafan ee laminated ayaa leh kalsooni sare, caabbinta kulaylka wanaagsan, alxanka wanaagsan, iyo qaabka caadiga ah, oo ku habboon wax soo saarka dusha sare ee tooska ah. Khasaaradu waa in heerka u qalma uu yar yahay, qiimuhuna uu sarreeyo, inductance-ku uu yar yahay, qiimaha Q uu yar yahay. Guud ahaan, inductor multilayer ma arki karo xariiqda, inductor multilayer wuxuu leeyahay kuleyl wanaagsan, iyo qiimaha ESR waa ka yar yahay. Waa imisa kuul magnetic induction? Waxaad nagagala tashan kartaa waxyaabaha aad xiisaynayso!

2. Faa'iidooyinka inductors-ka la-saaray ee SMD way ka duwan yihiin kuwa kale:
A. Cabbir yar.
B. Alxan aad u fiican iyo iska caabin alxan, oo ku habboon alxanka socodka iyo alxanka dib u qulqulka.
C. Wareegga xiran, ma jiro faragelin wadajir ah, oo ku habboon rakibidda cufnaanta sare.
D. Aan jiho ahayn, muuqaal habaysan oo toos ah dhejinta balastar.
