AC automotive qib tuab zaj duab xis resistor tsim los ntawm pawg Yageo yog tsim rau ultra- ruaj khov, qis- suab nrov ua haujlwm hauv cov khoom siv hluav taws xob precision. Nws yog AEC-Q200-tsim nyog automotive-qib tuab zaj duab xis SMD nti resistor- lub ntsiab robust, nqi-zoo tshuaj rau tsis-precision automotive circuits uas yuav tsum tau muaj kev ntseeg siab nyob rau hauv hnyav ib puag ncig, nrog screen-printed cermet tuab zaj duab xis, halogen-free kev tsim kho, thiab tag nrho ua raws li automotive qauv. Nws ua rau qhov sib txawv ntawm cov yeeb yaj kiab dav dav dav (RC) thiab ultra-precision nyias zaj duab xis (RT) rau cov tshuab tsheb uas xav tau kev ua haujlwm ntev tshaj qhov tseeb. BEC sawv cev thiab muag Yageo's AC series ntawm resistors.

Yam ntxwv
Substrate: 96% alumina (Al₂O₃) rau rigidity thiab thermal tsis kam.
Resistive Layer: Screen-printed cermet tuab zaj duab xis (10-25μm) nrog laser trimming rau lub hom phiaj kam rau ua.
Kev txiav tawm: Ag-Pd sab hauv electrodes → Ni underlayer → matte Sn txheej txheej (Pb-dawb, RoHS-raws li), txo qis kev tiv thaiv thiab tin whiskering.
Overcoat: Halogen-dawb iav-epoxy hybrid rau ya raws / kev tiv thaiv tshuab.
Marking: Laser-printed qhov tseem ceeb (0603+); 0201/0402 unmarked vim chaw.
100% AOI & Pulse Load Screening: Tshem tawm qhov ua tsis tiav thaum ntxov rau kev ua haujlwm ntawm qib tsheb.
Automotive Reliability & Ua raws cai
AEC-Q200 Tsim Nyog: Validated rau thermal cycling (-55℃rau +155 degree, 1000 cycles), av noo (85℃/ 85% RH, 1000h), vibration (30g, 10–2000Hz), thiab poob siab (100g, 0.5ms) nrog ± 1% ua haujlwm tsawg dua.
Moisture Sensitivity Level (MSL) 1: Tsis muaj kev txwv hauv pem teb tom qab qhib (tsis xav tau ci).
Environmental Compliance: RoHS/REACH-raws li, halogen-dawb, Pb-dawb; J-STD-020D solder tshaj (260℃ncov, 30s max saum 217 degree).
Lub neej ua haujlwm: 8000h ntawm lub zog ntsuas rau lub sijhawm ntev ntawm lub tsheb ua haujlwm.

FAQ
Q1: Dab tsi kam rau ua thiab TCR qhov tseem ceeb muaj rau AC series?
A1: Kev kam rau siab thiab TCR (Tsuas Coefficient of Resistance) yog sib npaug rau cov nqi tsheb / kev ua haujlwm sib tw- tsis muaj ultra- nruj precision specs (cov no yog tshwj tseg rau RT nyias zaj duab xis series). Cov kev xaiv kam rau ua yog raws li hauv qab no:
± 5%.
± 1%: Nruab nrab-precision (infotainment, HVAC tswj, BMS auxiliary circuits).
± 0.1% / ± 0.5%: nruj- kam rau ua qhov sib txawv (kev txiav txim tshwj xeeb nkaus xwb- rau cov khoom siv hluav taws xob uas xav tau me ntsis siab dua).
Q2: Puas yog AC series SMD tuab zaj duab xis resistors tsau lossis hloov pauv tau?
A2: Lawv yog cov resistors ruaj khov - lawv cov nqi tiv thaiv tau teeb tsa thaum tsim khoom (laser-trimmed) thiab tsis tuaj yeem hloov kho hauv - Circuit Court. Hloov pauv SMD resistors (trimmers / potentiometers) yog cov khoom sib cais rau calibration / tuning.
Q3: AEC-Q200 kev tsim nyog yog dab tsi, thiab qhov kev xeem AC series dhau?
A3: AEC-Q200 yog lub ntiaj teb automotive hluav taws xob tiv thaiv kev ntseeg tau tus qauv rau cov khoom siv tsis zoo (resistors, capacitors, inductors). Yageo's AC series yog 100% AEC-Q200 Rev. C tsim nyog, thiab tag nrho cov ntau lawm tau dhau los ntawm cov nram qab no nruj automotive kev ntsuam xyuas nrog tsawg dua los yog sib npaug rau ± 1% kev hloov pauv (Yageo's official spec).
