NTC qhov ntsuas kub tsis zoo coefficient thermistor ua haujlwm
NTC yog qhov luv luv ntawm Tsis Txaus Kev Ntsuas Kub, uas txhais tau tias muaj qhov ntsuas kub tsis zoo. Nws hais txog cov khoom siv semiconductor lossis cov khoom siv sib xyaw nrog qhov ntsuas kub tsis zoo loj. Cov tshuaj tiv thaiv NTC thermistor yog qhov ntsuas kub tsis pom zoo coefficient thermistor. Nws yog ua los ntawm cov hlau oxide xws li manganese, cobalt, npib tsib xee thiab tooj liab, thiab yog tsim los ntawm cov txheej txheem ceramic. Cov ntaub ntawv hlau oxide tag nrho muaj cov yam ntxwv semiconductor vim tias lawv zoo sib xws hauv kev siv hluav taws xob rau cov khoom siv semiconductor xws li germanium thiab silicon. Thaum lub ntsuas kub tsawg, cov naj npawb ntawm cov tsheb thauj khoom (hluav taws xob thiab lub qhov) ntawm cov khoom siv oxide no yog qhov me me, yog li tus nqi tsis kam ntawm qhov ntawd yog qhov siab; raws li qhov ntsuas kub nce ntxiv, tus naj npawb ntawm cov nqa khoom nce ntxiv, yog li tus nqi tsis kam tsawg dua. Tus NTC cov khoom siv hluav taws xob sib txawv los ntawm 100 txog 1000000 ohms ntawm chav tsev kub thiab muaj qhov ntsuas kub ntawm qhov ntsuas kub ntawm -2% rau -6.5%. NTC thermistor NTC thermistor dav siv nyob rau hauv ntsuas kub, ntsuas kub, ntsuas kub thiab lwm yam.
