Cov hlau oxide zaj duab xis ruaj khov uas tsim los ntawm BEC yog ib hom khoom siv hluav taws xob tsis zoo uas tsis yog - tus nqi kho tau, tsim los ntawm kev tso cov yeeb yaj kiab nyias ntawm cov hlau oxide (xws li, tin oxide, ruthenium oxide) mus rau cov khoom siv hluav taws xob (ceramic substrate) - feem ntau ntawm thermal decomposition lossis sputtering. Nws yog rugged, siab -kev ua tau zoo sib txawv ntawm cov yeeb yaj kiab resistors, sib npaug zoo dua thermal stability, siab - kub siab, thiab lub zog tuav dua li cov qauv hlau zaj duab xis (NiCr) resistors, thaum tuav siab dua cov pa roj carbon -raws li resistors. Nws yog dav siv nyob rau hauv siab - kub, nruab nrab- lub zog, thiab hnyav- ib puag ncig circuits (kev lag luam, tsheb, hluav taws xob hluav taws xob) qhov kev ua haujlwm ruaj khov thiab kev ua haujlwm ruaj khov nyob rau hauv tshav kub yog qhov tseem ceeb.

Yam ntxwv
Substrate:High -purity 96%+ alumina (Al₂O₃) ceramic (thicker dua hlau zaj duab xis substrates) - muab superior thermal conductivity, hluav taws xob rwb thaiv tsev, thiab mechanical rigidity kom dissipate tshav kub thiab tiv thaiv warping nyob rau hauv thermal stress.
Resistive Txheej:Ib zaj duab xis nyias (2–10μm) ntawm cov hlau oxide alloy (cov khoom siv txhais tau tias) - feem ntau yog tin dioxide (SnO₂) (qib tus qauv) lossis ruthenium oxide (RuO₂) (siab- qib / qib tshwj xeeb), feem ntau sib xyaw nrog antimony oxide rau kev tiv thaiv tuning. Deposited ntawm thermal decomposition (feem ntau) los yog sputtering rau uniform film thickness.
Trimming:Lub helical zawj yog txiav rau hauv oxide zaj duab xis (laser trimming rau ± 1% qib precision, mechanical trimming rau ± 5% tus nqi- qib optimized) kom ntsuas qhov tseeb tus nqi kuj.
Kev txiav txim siab:Nickel- tooj liab hlau kawg lub kaus mom nrog cov nickel barrier txheej (tiv thaiv corrosion, tin whiskering, thiab oxidation) - haum nrog axial lead xov hlau (THT) (tseem ceeb tshaj plaws) los yog solderable matte tin contacts (SMD variants). Tsim los rau siab -kub soldering compatibility (260℃+).
Txheej tiv thaiv:Cov iav tawv los yog iav- epoxy txheej (vs. epoxy rau hlau zaj duab xis resistors) - tshav kub-resistant, chemically inert, thiab impermeable rau ya raws / plua plav. Shields oxide zaj duab xis los ntawm thermal shock, corrosion, thiab mechanical puas; laser- luam tawm cov cim kev tiv thaiv / kam rau ua (ntawm THT variants) raug siv ntawm no.

FAQ
Q1: Dab tsi kam rau ua thiab TCR qhov tseem ceeb muaj rau cov hlau oxide zaj duab xis ruaj khov resistors?
A1: Kev kam rau siab (precision) thiab TCR (Temperature Coefficient of Resistance, thermal stability) yog sib npaug rau cov kev xav tau sib txawv ntawm cov qauv tsim- cov nqi me me=siab dua precision / ruaj khov:
Tolerance Options:
± 0.01% / ± 0.05%: Ultra- precision (cov khoom siv kuaj, kuaj mob, kev siv hluav taws xob hauv dav hlau).
± 0.1%.
± 1%.
TCR Options
± 5 / ± 10 ppm / degree: Ultra- ruaj khov (siab- qhov kub thiab txias: automotive engine bays, industrial furnaces).
± 25 ppm / degree: Standard precision (feem ntau -telecom, xam, automotive infotainment).
± 50 / ± 100 ppm / degree: Nqi-kev ruaj ntseg zoo (tsawg-kub-variation circuits: cov khoom siv hluav taws xob, khoom siv hauv tsev).
Q2: Puas yog cov hlau oxide zaj duab xis resistor zoo ib yam li cov pa roj carbon monoxide resistor?
A2: Tsis yog-lawv muaj qhov sib txawv hauv kev ua tau zoo thiab kev tsim kho, nrog cov hlau oxide raws li cov rugged, siab dua - precision upgrade rau carbon zaj duab xis:
Carbon zaj duab xis: Tsawg tus nqi, ± 5% / ± 10% kam rau ua, tsis zoo thermal stability (± 150-600 ppm / degree), max temp +125 degree, suab nrov- rau tsis yog -precision, qis- tshav kub circuits (xws li, yooj yim teeb pom kev zoo, hloov).
Hlau oxide zaj duab xis resistors: Tus nqi nruab nrab, ± 1% / ± 5% kam rau ua, zoo dua thermal stability (± 100-300 ppm / degree), max temp +200℃+, low-rau- suab nrov nruab nrab-rau hnyav- ib puag ncig, nruab nrab ntawm kev siv hluav taws xob, piv txwv li hauv qab -hood).
Hlau oxide zaj duab xis tsau resistors tsis muaj cov pa roj carbon degradation, yog li lawv muaj kev ruaj ntseg ntev dua -lub sij hawm ruaj khov dua li cov roj carbon zaj duab xis resistors.
