Cov yeeb yaj kiab hlau ruaj khov uas tsim los ntawm BEC yog ib hom khoom siv hluav taws xob passive nrog qhov ruaj khov, tsis yog - kho tus nqi kho tau, tsim los ntawm kev tso cov yeeb yaj kiab nyias nyias ntawm cov hlau (lossis hlau alloy) mus rau ib qho insulating ceramic substrate. Nws yog qhov tseeb - tsom ntsoov rau qhov sib txawv ntawm qhov sib txawv, muab qhov tseeb zoo dua, kev ruaj ntseg, thiab lub suab qis dua li cov pa roj carbon zaj duab xis / carbon muaj pes tsawg leeg resistors- ua rau nws yog ib qho tseem ceeb hauv cov neeg siv khoom, kev lag luam, thiab tsheb hluav taws xob rau cov teeb liab- txoj kev, kev tsis ncaj ncees, thiab nruab nrab - fais fab circuits.

Yam ntxwv
Substrate:High -purity 96% alumina (Al₂O₃) ceramic (insulating, thermally conductive, thiab mechanically rigid) kom dissipate tshav kub thiab tiv thaiv warping nyob rau hauv thermal stress.
Resistive Txheej:A μm- nplai nyias zaj duab xis (1–5μm) ntawm npib tsib xee-chromium (NiCr) alloy (feem ntau) - lossis tin -oxide / tantalum-nitride rau kev siv tshwj xeeb - tso ntawm sputtering / evaporation (xyuas cov zaj duab xis tuab kom zoo ib yam).
Laser txiav:Lub helical zawj yog laser-txiav rau hauv zaj duab xis los txiav kev ua haujlwm rau lub hom phiaj kam rau ua (ib kauj ruam tseem ceeb tshaj plaws rau kev ua tiav siab precision).
Kev txiav txim siab:Hlau kawg caps (tooj liab / npib tsib xee) nrog Pb-dawb solderable hu (SMD) lossis axial lead xov hlau (THT); nickel barrier txheej tiv thaiv corrosion / tin whiskering (tseem ceeb rau ntev -kev ntseeg tau ntev).
Txheej tiv thaiv:Halogen- iav dawb- epoxy / epoxy overcoat uas tiv thaiv zaj duab xis los ntawm ya raws, plua plav, tshuaj lom neeg, thiab kev puas tsuaj; laser- luam tawm cov cim kev tiv thaiv / kam rau ua (ntawm cov pob loj dua) raug siv ntawm no.

FAQ
Q1: Dab tsi kam rau ua thiab TCR qhov tseem ceeb muaj rau cov yeeb yaj kiab hlau ruaj ruaj?
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: Dab tsi yog qhov kev ua haujlwm kub ntawm cov yeeb yaj kiab hlau ruaj khov resistors?
A2: Zoo tag nrho cov kev lag luam / tsheb- qib hlau zaj duab xis resistors muaj qhov dav ntawm kev khiav hauj lwm kub ntawm -55℃rau +155℃- haum rau huab cua kub caij tsheb kauj vab hauv ib puag ncig hnyav (xws li, tsheb cav bays, kev lag luam enclosures, khoom siv sab nraum zoov telecom). Cov neeg siv khoom qib sib txawv yuav muaj qhov nqaim me ntsis (-40℃rau +125 degree), tab sis tseem muaj zog dua li cov pa roj carbon monoxide ruaj khov.
