Inductors tuaj ntau hom, thiab txhua tus ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob. Cov inductors muaj nyob rau hauv kev siv hluav taws xob siab, kev siv suab nrov, xov tooj cua zaus, teeb liab, thiab kev sib cais. Ntawm no yog saib cov hom inductors, thiab seb txhua tus feem ntau siv li cas.
kab hauv qab
Coupled inductors qhia txoj kev sib nqus thiab cuam tshuam ib leeg. Coupled inductors feem ntau yog siv los ua kev hloov pauv los nce lossis nqis qis qis lossis muab kev tawm tswv yim cais. Cov no kuj tseem siv rau hauv cov ntawv thov uas yuav tsum muaj kev sib nrig sib inductance.
Multilayer inductors
Multilayer inductors muaj txheej txheej ntawm coiled hlau uas raug mob nyob ib ncig ntawm lub hauv paus tseem ceeb. Ntxiv cov khaubncaws sab nraud povtseg ntawm coiled hlau rau ib qho inductor tsub kom qhov inductance, thiab nws tsub kom lub capacitance ntawm cov xov hlau. Cov inductors pauv tawm ntau dua inductance rau qhov qis tshaj plaws ua haujlwm zaus.
kab hauv qab
Inductors uas yog molded rau hauv yas los yog ceramic vaj tse yog hu ua molded inductors. Feem ntau, cov inductors no muaj cylindrical lossis bar daim ntawv thiab tuaj yeem pom nrog ntau hom kev xaiv winding.
YPower Inductors
Fais fab inductors muaj nyob rau hauv ntau hom qauv thiab qib zog. Cov inductors suav nrog txhua yam los ntawm qhov chaw mount inductors uas tuaj yeem tuav ob peb lub amps mus rau hauv lub qhov thiab chassis mount fais fab inductors uas tuaj yeem lis kaum mus rau pua pua amps.
Vim tias lub zog inductors raug rau cov tam sim no ntau, cov no yuav tsim cov hlau nplaum loj. Txhawm rau tiv thaiv cov hlau nplaum no los ntawm kev ua suab nrov hauv lwm qhov ntawm lub voj voog, cov hlau nplaum tiv thaiv inductors yuav tsum siv yog tias ua tau.
RF inductors
High-frequency inductors, tseem hu ua xov tooj cua zaus (RF) inductors, yog tsim los ua haujlwm ntawm cov zaus siab. Cov inductors feem ntau muaj qhov ua haujlwm siab dua thiab qis dua qhov ntsuas tam sim no. Feem ntau RF inductors muaj cov tub ntxhais huab cua es tsis yog ferrite lossis lwm yam khoom siv inductance-boosting core. Qhov no yog vim qhov nce hauv kev poob thaum cov ntaub ntawv tseem ceeb tau siv los txo qhov kev khiav hauj lwm zaus ntawm inductor.
Vim tias kev khiav hauj lwm zaus ntawm cov inductor, nws yog ib qho tseem ceeb kom txo tau tawm tsam ntau qhov chaw ntawm kev poob - txawm tias nws yog los ntawm cov nyhuv ntawm daim tawv nqaij, cov nyhuv sib thooj, los yog kab mob parasitic capacitance. Cov tawv nqaij thiab qhov sib thooj cuam tshuam ua rau muaj kev tiv thaiv ntawm ib qho inductor. Ob peb cov tswv yim txo cov kev poob no, suav nrog honeycomb thiab kab laug sab web coils kom txo tau cov kab mob cab. Tsis tas li ntawd, cov xov hlau litz feem ntau siv los txo cov nyhuv ntawm daim tawv nqaij.
Khob
Ib choke yog ib qho inductor uas thaiv cov mem tes siab thaum tso qis zaus pulses los ntawm. Lub npe yog los ntawm kev choking tawm los yog thaiv ntawm high-frequency signals. Muaj ob chav chokes:
- Lub zog thiab lub suab zaus chokes feem ntau muaj cov tub ntxhais hlau kom nce inductance thiab ua kom cov lim dej zoo dua.
- RF chokes siv hlau hmoov lossis ferrite hlaws dai ua ke nrog cov qauv winding nyuaj kom txo tau cov kab mob cab thiab ua haujlwm tau zoo ntawm ntau zaus. Ntau zaus chokes siv cov tsis sib nqus los yog cua cores.
Nto Mount Inductors
Lub laub rau cov khoom siv me me thiab ntau lub xov tooj ntawm tes tau coj mus rau qhov tawg hauv kev xaiv rau saum npoo mount inductors. Surface mount inductors feem ntau siv hauv DC-DC converters, EMI filtering, lub zog cia, thiab lwm yam kev siv. Qhov me me thiab hneev taw ua rau saum npoo mount inductors yog ib qho tseem ceeb hauv lub xov tooj ntawm tes thiab portable electronic designer's toolbox.
Nto mount inductors muaj nrog thiab tsis muaj kev tiv thaiv sib nqus, nrog lub peev xwm tam sim no ntau dua 10 amps, thiab nrog kev poob qis. Surface mount inductors feem ntau siv cov hlau los yog ferrite core lossis tshwj xeeb winding cov tswv yim los ua kom zoo dua qhov kev ua tau zoo ntawm inductor. Qhov no kuj tseem pab tswj tau qhov hneev taw me me thiab daim foos.
Type of Inductor Cores
Cov khoom tseem ceeb ntawm inductor plays lub luag haujlwm loj hauv kev ua haujlwm ntawm inductor. Cov khoom tseem ceeb ncaj qha cuam tshuam rau qhov inductance ntawm inductor. Nws txiav txim siab qhov ua haujlwm siab tshaj plaws, nrog rau lub peev xwm tam sim no ntawm inductor.
- Air cores muaj ntau zaus ua haujlwm vim tsis muaj qhov poob tab sis muaj qhov qis dua.
- Iron cores muaj qhov tsis muaj zog nrog siab inductance. Core poob, eddy tam sim no, sib nqus saturation, thiab hysteresis txwv kev khiav hauj lwm zaus thiab tam sim no.
- Ferrite cores muaj cov khoom siv tsis zoo ceramic rau kev ua haujlwm ntau dua. Sib nqus saturation txwv lub peev xwm tam sim no.
- Toroidal cores yog cov cores zoo li donuts uas txo cov hluav taws xob EMI thiab muab siab inductance.
- Laminated cores muaj qhov siab inductance nrog qis hysteresis thiab eddy tam sim no poob.
