AR03BTCX1001是Viking(光颉)电子推出的一款0603封装薄膜贴片电阻,属于小功率高精度电阻范畴,专为对阻值精度、温度稳定性要求较高的信号级电路设计,兼顾体积紧凑性与环境适应性,适用于工业、汽车、消费电子等多领域。
该电阻的关键参数直接决定了其应用场景,具体如下:
标称阻值为1kΩ,精度等级达**±0.1%**——这一精度远高于普通碳膜电阻(典型±5%),可满足精密分压、电流采样、基准电压搭建等对阻值准确性要求苛刻的电路需求,减少系统误差。
额定功率为100mW,与0603封装(尺寸1.6mm×0.8mm)的小体积设计适配,既满足信号级电路的功率承载需求,又避免了大体积电阻对PCB空间的占用,适合高密度布线场景。
温度系数(TCR)为**±25ppm/℃**,表示温度每变化1℃,阻值变化约0.0025%。以典型工作温差(如25℃→125℃)计算,阻值总变化量仅为0.25%,结合初始±0.1%精度,全温区阻值偏差可控制在±0.35%以内,稳定性显著优于普通电阻(如碳膜电阻TCR通常达±200ppm/℃以上)。
工作温度覆盖**-55℃+155℃**,满足工业级(-40℃+85℃)与汽车级(-40℃~+125℃)的环境要求,可在极端温度下(如户外低温、汽车发动机舱高温)稳定工作,无需额外散热或温度补偿。
0603封装属于贴片电阻的主流小封装之一,具备以下优势:
Viking(光颉)是全球知名的电阻制造商,在薄膜电阻领域拥有20余年技术积累:
结合性能参数,AR03BTCX1001的核心应用场景包括:
AR03BTCX1001的核心竞争力体现在以下四点:
该产品是信号级电路中替代普通电阻、提升系统精度与稳定性的理想选择,尤其适合对体积、精度、环境适应性有综合要求的场景。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
