AR02BTC5102是Viking(光颉) 推出的0402封装高精度薄膜贴片电阻,属于该品牌针对小功率高精度场景的核心产品线。产品采用薄膜电阻技术,区别于普通碳膜、金属膜电阻,核心优势聚焦于高阻值精度、低温度漂移、宽工作温区,适配对电性能稳定性要求严苛的电子设计,是中高端模拟电路、工业控制等领域的常用元件。
标称阻值为51kΩ(编码“5102”,对应51×10²Ω),精度等级为**±0.1%**——属于薄膜电阻的高精度规格,可满足多数模拟电路对阻值一致性的要求,无需额外校准即可用于信号调理、反馈网络等场景,避免因精度偏差导致电路性能波动。
温度系数为**±25ppm/℃**,表示温度每变化1℃,阻值变化量为:
[ 51kΩ \times 25 \times 10^{-6} = 1.275Ω ]
该参数属于薄膜电阻的优质水平,可有效降低温变对电路的影响,尤其适合温度波动较大的工业环境。
覆盖**-55℃~+155℃**,满足工业级宽温需求,适配户外传感器、汽车发动机舱周边电路等极端环境应用。
英制代码对应公制尺寸1.0mm×0.5mm,体积小巧,适合高密度PCB布局(如智能手机主板、可穿戴设备、小型工业控制器);支持SMT自动化贴装,生产效率高,适配批量生产需求。
采用真空溅射/沉积工艺制备电阻膜,相比传统电阻技术具有三大优势:
AR02BTC5102凭借高精度、宽温稳定、小体积等特点,成为中高端电子设计中替代普通电阻的优选方案,广泛覆盖工业、医疗、消费电子等领域。

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.
