AR03BTCX1500是Viking(光颉)电子推出的一款0603封装高精度薄膜贴片电阻,专为对阻值精度、温度稳定性要求严苛的电子电路设计,兼具小型化、低功耗等特点,广泛适配工业控制、通信设备、精密仪器等多领域应用。
该电阻属于光颉旗下精密薄膜电阻系列,采用成熟的真空沉积工艺制造,区别于厚膜电阻的印刷工艺,薄膜技术可实现更高阻值精度与更低温度系数。0603封装(英制尺寸,对应公制1608)为小型化设计,适合高密度PCB布局;100mW功率等级满足大多数低功耗电路需求,是平衡精度、体积与功耗的典型选型。
标准阻值为150Ω,精度等级达**±0.1%**——远高于普通碳膜电阻(通常±5%),可有效减少精密电路的系统误差,尤其适合需要精准分压、限流的场景(如万用表校准电路)。
温度系数为**±25ppm/℃**,意味着环境温度每变化1℃,阻值仅变化150Ω×25×10⁻⁶=3.75mΩ,远低于厚膜电阻(通常±100ppm/℃以上)。低TCR确保电阻在宽温范围内保持阻值稳定,避免温度波动导致电路性能漂移。
支持**-55℃+155℃**宽温工作,覆盖工业级(通常-40℃+85℃)与部分高温场景(如汽车发动机舱周边),满足恶劣环境下的长期稳定运行。
薄膜电阻通过真空沉积在陶瓷基底形成电阻层,相比厚膜电阻:
±0.1%精度+±25ppm/℃温系的组合,可解决两类典型问题:
0603封装是主流小型贴片电阻尺寸之一,适合5G基站、智能穿戴等对PCB空间要求严格的产品,可减少电路布局面积,降低整机体积与成本。
光颉作为专业电阻制造商,AR03BTCX1500通过多项可靠性测试:
这些测试确保产品在复杂环境下长期稳定工作,降低设备维护成本。
综上,AR03BTCX1500是一款高精度、低温漂、小型化的薄膜贴片电阻,凭借Viking的制造工艺与可靠性能,成为多领域精密电路设计的优选元件。

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.
