Raws li ib qho ntawm feem ntau cov cheeb tsam hauv cov hluav taws xob hluav taws xob, tsim tawm cov qauv kev tsim ncaj qha cuam tshuam rau lawv cov kev ua tau zoo thiab kev ntseeg tau. Los ntawm cov txheej txheem theem pib, tiv taus feem ntau muaj peb ntu: lub cev tiv taus, ua, thiab ntim khoom. Lub cev tiv thaiv yog cov tseem ceeb ua haujlwm txheej, ua tiav cov kev txwv tam sim no los ntawm cov khoom tsis kam ntawm cov ntaub ntawv tshwj xeeb. Cov ntaub ntawv nquag muaj suav nrog cov yeeb yaj kiab carbon, hlau zaj duab xis, fuab zaj duab xis, thiab xaim {{} txhab alloys. Qhov kev xaiv ntawm cov khoom sib txawv txiav txim siab cov khoom tseem ceeb xws li cov resistor qhov precision, lub zog muaj peev xwm, thiab kub coefficient.
Cov qauv coj tau muab faib ua ob hom tseem ceeb: axial thiab radial. Cov qub yog siv nyob rau hauv kev ua yeeb yam hauv kev plug - hauv cov tom kawg rau cov khoom lag luam zoo niaj hnub (SMT). Nyob rau hauv high - precision daim ntawv thov, hlau ua yauv hluav taws xob hluav taws xob tsis kam, ua kom ntev}}}}}}}} xyoo kev sib txuas tsis muaj peev xwm. Qhov kev xaiv ntawm cov khoom ntim yuav tsum sib piv cov cua sov dissipation efficiency thiab ib puag ncig compatibility. Piv txwv li, epoxy cob ntim ntim yog qhov haum rau cov chaw sib koom ua ke, thaum cov tub rog qib lossis cov khoom siv hlau kom tau raws li lub siab thiab xeb tsis kam ua rau huab cua.
Hauv kev ua lag luam kev lag luam thoob ntiaj teb, cov qauv kev ua kom tsim tawm hauv cov khoom siv txuas ntxiv mus tsav tsheb thev naus laus zis. Piv txwv li, tuab - zaj duab xis} Kev ua yeeb yaj kiab miniaturing, ntsib qhov chaw {{l} txuag tau ntawm cov neeg siv khoom hluav taws xob. Siab - fais fab wirewon distors, nrog lawv cov multi fayinged insulating insulating cov qauv pob txha pob txha pob txha pob txha pob txha Raws li lub ntiaj teb hluav taws xob tsim kev lag luam hloov kho, tsim kho cov qauv ntawm cov txheej txheem ntawm cov neeg siv cov kev sib tw ua haujlwm. Nkag siab txog cov ntsiab cai tseem ceeb pab cov neeg siv khoom lag luam txawv teb chaws xws li cov ntaub ntawv lag luam xws li cov khoom siv kho mob xws li cov khoom siv kho mob xws li cov khoom siv kho mob, uas muaj feem xyuam kev ruaj khov yog qhov tseem ceeb.
