Viking(光颉)AR05BTCW5003是一款工业级精密表面贴装薄膜电阻,针对对阻值精度、温区稳定性要求严苛的场景设计,兼顾小体积集成与可靠性。其核心优势可总结为:
标称阻值500kΩ,精度±0.1%(即实际阻值偏差≤500Ω),远优于普通碳膜电阻(±1%~±5%)。该精度可直接用于精密分压、参考电压生成等场景,无需额外校准。
±25ppm/℃,指每变化1℃,阻值漂移为500kΩ×25×10⁻⁶=12.5Ω。在环境温度变化40℃时,漂移仅500Ω(与精度阈值一致);即使在-55℃~+155℃极端温区,漂移约2.6kΩ,仍能保持电路基本稳定。
-55℃~+155℃,符合工业级温区标准,支持户外设备、汽车子系统(如发动机舱周边)等低温启动、高温持续工作场景。
英制尺寸0.08″×0.05″(公制2.0mm×1.2mm),体积小巧,适配便携式设备、小型化模块的高密度布局,同时降低电路重量与成本。
采用镍铬合金薄膜沉积工艺,相比厚膜电阻:
通过温度循环(-55℃~+155℃,500次)、湿度老化(85℃/85%RH,1000小时)、耐电压(1.5×150V,1分钟)等测试,符合IEC 61000工业标准,确保恶劣环境下性能不衰减。
AR05BTCW5003通过平衡精度、稳定性与体积,成为精密电子系统的高性价比选择,尤其适合对温区、可靠性要求严苛的工业与医疗场景。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
