faus resistors feem ntau yog siv nyob rau hauv rooj plaub uas lub rooj tsavxwm tsis tuaj yeem nteg tawm lossis lub teeb liab txhim kho, thiab qhov kev tiv thaiv dav dav ntawm qhov tseeb yog tsawg dua ± 10 feem pua. faus resistors muaj tsib qhov zoo.
1. Qhov zoo ntawm high-density / high-speed kis tau tus mob Circuit Court tsim.
Txhim kho qhov impedance txuam ntawm kab.
Shortening txoj kev ntawm cov teeb liab kis tau tus mob thiab txo cov kab mob parasitic inductance.
Tshem tawm ntawm inductive reactance generated nyob rau hauv nto mount los yog cartridge txheej txheem.
Txo cov teeb liab crosstalk, suab nrov thiab electromagnetic cuam tshuam.
2. Qhov zoo ntawm kev hloov qhov chaw tso tawm resistors.
Kev txo qis ntawm cov khoom siv passive thiab nce qhov ntom ntom ntawm cov khoom siv ua haujlwm tso.
Kev txhim kho ntawm board thaiv muaj peev xwm vim qhov txo qis ntawm cov hlau lead-los ntawm qhov.
Vim tias qhov taw tes soldering raug txo, yog li qhov kev ruaj ntseg ntawm cov khoom siv hluav taws xob tom qab kev sib dhos tau zoo tuaj.
3. Lub faus resistor tom qab kev koom ua ke muaj qhov zoo hauv kev ruaj ntseg.
Qhov poob ntawm faus resistors tom qab txias thiab cua sov cycles yog tsawg heev, txog 50 × 10-6, thaum poob ntawm lwm yam discrete resistive Cheebtsam yog 100 mus rau 300 × 10-6.
Nce hauv kev tiv thaiv ntawm li 2 feem pua tom qab cia ntawm 110 degree rau 10,000h.
Kev ntsuas kev ruaj ntseg hauv ntau qhov ntau zaus, tsawg dua 20GHz.
4. Tus nqi resistor ntawm ntau yam kev qhia tshwj xeeb tuaj yeem ua ke los ntawm kev hloov kho nws daim ntawv zoo, thiab nws tuaj yeem ua tau zoo nrog cov interline inductance.
5. Hauv kev tsim cov khoom siv rau cov khoom siv hluav taws xob siab discrete, cov cuab yeej siv hluav taws xob faus tuaj yeem txo cov txheej txheem thiab qhov loj ntawm PCB, thiab txo qhov zoo thiab tsim cov nqi ntawm PCB board.
Cov ntaub ntawv pov thawj resistor
Tam sim no, cov khoom siv hluav taws xob ntau dua yog Ni-P khoom, thiab cov ntsiab lus P dav dav yog li 10 feem pua. Lub resistivity ntawm cov khoom tuaj yeem hloov kho los ntawm kev kho cov thicknesses sib txawv ntawm cov khoom siv Ni-P thiab cov ntsiab lus P.
