Lub precision tsis kam alloy MANGANIN yog tshwj xeeb tshaj yog cov yam ntxwv ntawm qhov kub tsis tshua muaj coefficient ntawm 20 thiab 50 ° C nrog cov duab parabolic ntawm R (T) nkhaus, lub sij hawm ntev stability ntawm hluav taws xob tsis kam, tsis tshua muaj thermal EMF piv rau tooj liab thiab cov khoom ua haujlwm zoo.
Txawm li cas los xij, ntau dua thermal loads hauv qhov chaw uas tsis yog oxidizing tuaj yeem ua tau. Thaum siv rau precision resistors nrog siab tshaj qhov yuav tsum tau, cov resistors yuav tsum tau ua tib zoo stabilized thiab daim ntawv thov kub yuav tsum tsis txhob ntau tshaj 60 ° C. Tshaj qhov siab tshaj plaws ua haujlwm kub hauv huab cua tuaj yeem ua rau muaj kev tiv thaiv drift tsim los ntawm cov txheej txheem oxidizing.Yog li, kev ruaj ntseg ntev tuaj yeem cuam tshuam tsis zoo. Yog li ntawd, lub resistivity nrog rau qhov kub coefficient ntawm hluav taws xob kuj yuav hloov me ntsis. Nws kuj yog siv los ua cov khoom siv uas tsis tshua muaj nqi rau cov nyiaj solder rau cov hlau tawv tawv.
