AR03BTCX2003是Viking(光颉)推出的高精度薄膜贴片电阻,针对对阻值稳定性、精度要求苛刻的场景设计。核心参数清晰明确:
薄膜电阻采用真空溅射工艺形成电阻层,相比厚膜电阻,阻值一致性更好、长期漂移更小,是AR03BTCX2003高精度特性的核心支撑。
该电阻采用0603封装(英制尺寸,对应公制1608),尺寸约1.6mm×0.8mm×0.5mm,属于小型化贴片封装,可满足高密度PCB设计需求(如智能手机、智能手表等便携设备的模块集成)。
焊盘设计符合IPC-J-STD-001标准,无铅表面处理(通常为Sn/Pb或纯Sn),兼容回流焊、波峰焊等常规贴片工艺,焊接良率高;同时符合RoHS 6、REACH环保指令,无有害物质残留,适配全球市场要求。
±0.1%的精度意味着200kΩ电阻的实际阻值偏差仅±200Ω,可直接用于无需额外校准的精密场景:例如示波器的垂直衰减电阻、医疗监护仪的传感器信号放大电阻,避免因阻值偏差导致的信号失真或测量误差。
±25ppm/℃的TCR是其核心优势之一:温度每变化1℃,阻值仅变化0.0025%。以极端温差210℃(-55℃→+155℃)为例,阻值总变化仅0.525%,远低于普通厚膜电阻(±100ppm/℃以上,温差210℃变化2.1%)。这一特性使其在宽温环境下仍能保持稳定性能,如户外太阳能逆变器、车载传感器模块。
100mW功率在0603封装中属于“降额设计”(0603电阻最大额定功率通常为125mW),工作时发热低,可有效降低阻值漂移。Viking针对该产品的1000小时高温老化测试显示,阻值漂移≤0.1%,满足量产设备的长期一致性要求。
-55℃+155℃的宽温范围,覆盖了**工业级(-40℃+85℃)和汽车级(-55℃~+150℃)** 部分应用场景:
无需额外降额使用(在额定温区和功率下),可简化电路设计,降低成本。
Viking(光颉)是全球薄膜电阻领域的核心供应商,专注被动元件研发20余年,AR03BTCX2003通过了工业级可靠性认证(如IEC 61000-4-2静电放电测试),部分批次符合AEC-Q200汽车级标准。量产过程中采用100%阻值测试,确保每颗电阻均满足参数要求,可稳定供应汽车、工业、医疗等领域的批量订单。

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.
