Kev sib txuas thiab qhov sib txawv ntawm inductance thiab magnetic hlaws

1. Lub inductor yog lub zog cia khoom, thiab cov hlaws sib nqus yog lub zog hloov pauv (siv) cov khoom siv;

2. Inductors feem ntau yog siv hauv cov khoom siv hluav taws xob lim hluav taws xob, thiab cov hlaws sib nqus feem ntau yog siv rau hauv cov teeb liab loops rau EMC countermeasures;

3. Cov hlaws hlau nplaum feem ntau yog siv los cuam tshuam cov hluav taws xob hluav taws xob hluav taws xob, thaum inductors siv rau hauv qhov kev hwm no kom tsom mus rau kev cuam tshuam kev cuam tshuam. Ob leeg tuaj yeem siv los daws cov teeb meem EMC thiab EMI; ob txoj kev ntawm EMI, uas yog: hluav taws xob thiab conduction, sib txawv Txoj kev siv cov txheej txheem sib txawv, cov qub siv cov hlaws sib nqus thiab tom kawg siv inductance;

4, cov hlaws sib nqus yog siv los nqus cov teeb liab ultra-high zaus, zoo li qee qhov RF circuits, PLL, oscillating circuits, nrog rau ultra-high zaus nco circuits (DDRSDRAM, RAMBUS, thiab lwm yam) yuav tsum tau ntxiv cov hlaws sib nqus hauv cov khoom siv hluav taws xob, thiab cov inductance yog ib yam Lub zog cia tivthaiv yog siv nyob rau hauv ib tug LC oscillating Circuit Court, ib tug low-frequency lim Circuit Court, thiab lwm yam., thiab nws daim ntawv thov ntau zaus tsis tshua muaj tshaj 50 MHz;

5, lub inductor feem ntau yog siv rau kev sib txuam hauv Circuit Court thiab cov teeb liab kev tswj kom zoo, kev sib txuas dav dav thiab cov khoom siv hluav taws xob sib txuas. Sib nqus hlaws yog siv qhov chaw analog av thiab cov av digital ua ke. Sib nqus hlaws kuj siv rau cov kab teeb liab.

Qhov luaj li cas ntawm cov hlaws sib nqus (uas yuav tsum yog raws nraim cov yam ntxwv nkhaus ntawm cov hlaws sib nqus) nyob ntawm qhov zaus ntawm qhov cuam tshuam tsis zoo uas yuav tsum tau nqus los ntawm cov hlaws sib nqus. Cov hlaws sib nqus yog cov khoom siv hluav taws xob ntau zaus, tsis tshua muaj DC tsis kam thiab ua haujlwm siab. Vim hais tias chav tsev ntawm cov hlaws yog nominally raws li impedance nws tsim ntawm ib tug tej zaus, chav tsev ntawm impedance kuj yog ohms. Ib tug yam ntxwv nkhaus ntawm zaus thiab impedance feem ntau yog txuas nrog rau cov ntaub ntawv ntawm cov hlaws magnetic. Feem ntau, tus qauv yog 100MHz. Piv txwv li, 2012B601 txhais tau hais tias impedance ntawm cov hlau nplaum yog 600 ohms ntawm 100 MHz.
