Decoupling capacitors pab muab lub chaw them nqi tam sim hauv zos uas tiv thaiv qhov hluav taws xob los ntawm dipping thiab txoj kev bypass uas dampens ringing. Lub suab nrov ntawm PDS kuj tseem nyob hauv zos damped, pab hauv cheeb tsam hauv cheeb tsam tsis cuam tshuam los ntawm ripple ntawm lub dav hlau fais fab uas tuaj yeem cuam tshuam rau lub voj voog.

Lub hom phiaj ntawm kev siv lub tshuab hluav taws xob decoupling yog dab tsi?

Yog hais tias qhov input voltage poob, ces lub decoupling capacitor yuav yog muaj peev xwm muab lub zog txaus rau IC kom qhov voltage ruaj khov. Yog tias qhov hluav taws xob nce ntxiv, tom qab ntawd lub decoupling capacitor yuav tuaj yeem nqus lub zog ntau dhau los sim ntws mus rau IC, uas rov ua kom qhov hluav taws xob ruaj khov.

Lub hom phiaj ntawm kev siv cov khoom siv hluav taws xob hauv PCB yog dab tsi?

Lub decoupling ua haujlwm raws li a reservoir thiab ua nyob rau hauv ob txoj hauv kev kom stabilize qhov voltage. Thaum qhov voltage nce siab tshaj tus nqi ntsuas, lub decoupling capacitor absorbs cov nqi ntau dhau. Lub caij no, lub decoupling capacitor tso tawm cov nqi thaum lub zog poob kom ntseeg tau tias cov khoom ruaj khov.

Qhov twg yog decoupling capacitor siv?

Decoupling capacitors yog siv txhawm rau lim tawm qhov hluav taws xob tawm hluav taws xob thiab dhau los ntawm tsuas yog DC tivthaiv ntawm lub teeb liab. Lub tswv yim yog siv lub capacitor nyob rau hauv xws li ib txoj kev uas nws shunts, los yog absorbs lub suab nrov ua lub DC teeb liab kom du li sai tau.

Lub hom phiaj yog dab tsikev txiav txim?

Decoupling (Bypass) Capacitors

Ib lub decoupling capacitor txoj haujlwm yog txhawm rau txhawm rau lub suab nrov nrov hauv cov khoom siv hluav taws xob. Lawv siv cov hluav taws xob me me, uas tuaj yeem ua rau muaj kev phom sij rau ICs ilv, tawm ntawm qhov hluav taws xob.
