Qhov txawv ntawm inductor thiab zoo tib yam inductor | TAU TXAIS

Cov phooj ywg uas nkag siab inductors paub tias muaj ob hom inductors hauv kev faib cov inductors: shielded inductors thiab unshielded inductors. Hauv tsab xov xwm dhau los, peb kuj tau hais txog ob hom inductors no, tab sis tsis tau muab piv rau ua ke. Niaj hnub no, inductor tuam ntxhab tuaj nrog koj kom nkag siab qhov txawv ntawm shielded inductors thiab unshielded inductors.

Qhov sib txawv ntawm shielded inductors thiab unshielded inductors

Koj puas xav tias tag nrho cov inductors nyob ib puag ncig yog shielded inductors? Ib tug shielded inductor yog ib tug inductor nyob ib ncig ntawm lub magnetic core. Tsis yog txhua tus inductors nyob ib puag ncig los ntawm cov cores yog shielded inductors, xws li GNL inductors, uas tseem nyob ib puag ncig los ntawm cores tab sis tsis thaiv. Nws yog ib qho tseem ceeb kom paub qhov txawv shielded thiab unshielded inductors sab nraud los txiav txim seb lub inductor nyob ib puag ncig los ntawm cov hlau nplaum. Attack tus nqi ntawm inductance

Feem ntau hais lus, unshielded inductance enameled hlau yog nthuav tawm sab nraud yam tsis muaj ntaub thaiv npog npog; Shielding inductor nrog sib nqus shielding, zoo EMI tsis kam, txo cov electromagnetic cuam tshuam ntawm inductor mus rau lub ntiaj teb sab nraud, txo qhov cuam tshuam ntawm electromagnetic teb generated los ntawm Circuit Court rau lwm yam khoom.

Qhov tseeb, muaj qhov sib txawv loj ntawm shielded inductance thiab unshielded inductance yog tias shielded inductance yog kaw sib nqus Circuit Court, thaum lub unshielded inductance yog qhib magnetic circuit. Lub npe hu ua kaw sib nqus Circuit Court txhais tau hais tias tag nrho cov hlau nplaum kaw Circuit Court yog tsim los ntawm cov khoom sib nqus, thaum qhib magnetic Circuit Court txhais tau hais tias muaj qhov pom tseeb ntawm huab cua sib txawv hauv cov khoom sib nqus. Tapping tus nqi Inductor Co

Tsis tsuas yog lawv txawv, tab sis kuj muaj qee qhov sib xws. Lawv lub ntim feem ntau me me, qhov saum npoo yog yooj yim los lo, haum rau cov khoom siv tsis siv neeg, raws li qhov sib txawv ntawm cov neeg siv khoom los tsim cov qauv sib txawv rau cov neeg siv khoom xaiv. Hais txog hais lus, lub unshielded inductor tau zoo dua vuam tsis kam thiab tshav kub tsis kam, haum rau dav vuam thiab reflow vuam, nrog tus nqi qis.

Integrated inductor thiab hom inductor sib txawv

Lub precision ntawm kev sib xyaw inductor yog me ntsis siab dua li ntawm cov inductor zoo tib yam. Feem ntau, kev sib xyaw inductors tsuas yog 20% ​​raug, thaum peb lwm cov inductors yog 10% tseeb. Txawm tias qee qhov inductors muaj qhov raug zoo dua, xws li 5%, piv nrog 20% ​​rau kev sib xyaw inductors. Txij li thaum lub precision ntawm kev sib xyaw inductor tsis zoo, vim li cas thiaj muaj kev lag luam loj dua?

Qhov no yog vim kev sib xyaw inductors muaj qhov zoo ntawm cov nqi inductance. Nws muaj qhov nqaim ntawm qhov ntsuas qhov ntsuas. Feem ntau, nws tus nqi inductance tsawg dua 100uH, thiab qee hom kev sib xyaw inductors tuaj yeem ncav cuag tus nqi inductance tsawg dua 1uH. Tapping tus nqi inductor hais

Peb paub tias kev sib xyaw inductance thiab cov inductance zoo tib yam hauv cov lej, qhov sib txawv ntawm kev sib xyaw inductor tam sim no loj dua, yog tias lawv cov lej nkag siab yog 10 er, qhov sib xyaw ua ke tam sim no tuaj yeem ua tau ntau, qhov nruab nrab inductor tam sim no me, yog li qee qhov cov khoom ntawm cov kev xav tau ntawm tus lej tsis siab, tab sis nyob rau hauv cov ntaub ntawv ntawm cov tam sim no loj, daim ntawv thov ntawm kev sib xyaw inductance ntau dua, xws li khoos phis tawj thiab lwm yam.

Qhov no yog kev taw qhia ntawm inductors, yog tias koj xav paub ntau ntxiv txog thaj inductors, thov hu rau peb cov neeg muag khoom inductor.
