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

1. Inductors yog lub zog cia khoom, thaum cov hlaws sib nqus yog lub zog hloov pauv (siv) cov khoom siv; [1]
2. Inductors feem ntau yog siv nyob rau hauv lub hwj chim filtering circuits, thaum sib nqus hlaws yog feem ntau siv nyob rau hauv lub teeb liab circuits rau EMC countermeasures;
3. Cov hlaws hlau nplaum feem ntau yog siv los tiv thaiv electromagnetic tawg cuam tshuam, thaum inductance tsom rau kev cuam tshuam kev cuam tshuam. Ob leeg tuaj yeem siv los daws teeb meem EMC thiab EMI; Ob txoj hauv kev ntawm EMI, uas yog hluav taws xob thiab kev coj ua, txais yuav txoj hauv kev sib txawv rau txoj kev sib txawv. Cov qub siv cov hlaws sib nqus, thaum kawg siv inductance;
4. Cov hlaws sib nqus yog siv los nqus cov teeb liab ultra-high zaus, xws li qee qhov RF circuits, PLLs, oscillation circuits, thiab circuits uas muaj ultra-high zaus nco (DDRSDRAM, RAMBUS, thiab lwm yam) uas yuav tsum tau sib nqus hlaws dai ntxiv rau hauv zog input. Inductors yog lub zog cia khoom siv hauv LC oscillation circuits, nruab nrab thiab qis zaus lim circuits, thiab lawv daim ntawv thov ntau zaus tsis tshua muaj tshaj 50 MHz;
5. Inductance feem ntau yog siv rau kev sib txuam hauv Circuit Court thiab teeb liab kev tswj kom zoo, nrog rau kev sib txuas dav dav thiab cov khoom siv hluav taws xob sib txuas. Siv cov hlaws sib nqus nyob qhov twg analog thiab digital hauv av ua ke. Sib nqus hlaws kuj siv rau cov kab teeb liab.
Qhov loj ntawm cov hlaws sib nqus (tshwj xeeb, nws cov yam ntxwv nkhaus) nyob ntawm qhov zaus ntawm kev cuam tshuam yoj uas yuav tsum tau nqus los ntawm cov hlaws sib nqus. Cov hlaws sib nqus yog tsim los tiv thaiv cov kab mob siab, nrog rau DC tsis kam thiab kev ua haujlwm siab. Vim hais tias chav tsev ntawm magnetic hlaws yog nominal raws li impedance nws generates ntawm ib tug tej zaus, thiab chav tsev ntawm impedance kuj yog ohms. Cov ntaub ntawv ntawm cov hlaws sib nqus feem ntau muaj cov yam ntxwv nkhaus ntawm zaus thiab impedance. Feem ntau, tus qauv yog 100MHz, xws li 2012B601, uas txhais tau hais tias impedance ntawm cov hlau nplaum yog 600 ohms ntawm 100MHz.
