ARG06DTC4701是Viking(光颉)推出的1206封装薄膜贴片电阻,核心参数如下表所示,覆盖工业级电路的基础性能要求:
参数项 规格值 备注 电阻类型 金属薄膜电阻 采用NiCr薄膜沉积工艺 标称阻值 4.7kΩ(编码:4701) 4700Ω,激光微调实现精度 精度等级 ±0.5% 高于常规贴片电阻(±1%~±5%) 额定功率 250mW(0.25W) 持续工作功率 最大工作电压 200V 峰值电压限制 温度系数(TCR) ±25ppm/℃ 温度漂移极小 工作温度范围 -55℃ ~ +155℃ 工业级宽温标准 封装尺寸 1206(英制) 约3.2mm×1.6mm,适配SMT 环保标准 RoHS compliant 无铅无卤ARG06DTC4701采用1206标准贴片封装,尺寸紧凑(3.2mm×1.6mm),可直接适配主流SMT(表面贴装技术)生产线,实现高效自动化焊接;同时体积小巧,能有效节省电路板空间,适合高密度集成设计。
该电阻采用镍铬(NiCr)金属薄膜工艺:
相比厚膜电阻,薄膜工艺的阻值均匀性更好、温度系数更低;相比碳膜电阻,高频特性更优(适合射频电路)、稳定性更强(长期使用阻值漂移小)。
±0.5%的精度等级可满足信号调理、反馈电路等对阻值敏感的场景,避免因阻值偏差导致的电路输出误差(例如:电源反馈电阻的精度直接影响输出电压稳定性)。
±25ppm/℃的温度系数意味着:环境温度每变化1℃,阻值仅变化0.0025%。即使在-55℃~+155℃的宽温范围内,阻值稳定性仍能保持在可接受区间,适合工业、汽车等温度波动大的场景。
覆盖工业级温度标准(-55℃~+155℃),无需额外散热或温度补偿设计,可在低温严寒、高温湿热环境下持续稳定工作。
250mW额定功率与200V最大工作电压,可满足多数低压小功率电路需求(如传感器信号放大、电源滤波、射频匹配等),无需并联/串联电阻即可覆盖常规功率场景。
ARG06DTC4701因高精度、宽温、小体积等特性,广泛应用于以下领域:
Viking(光颉)是全球知名被动元器件制造商,专注电阻研发20余年,ARG系列薄膜电阻为成熟产品线。ARG06DTC4701经过严格可靠性测试:
每批次产品均出具出厂检测报告,阻值偏差、温度系数等指标符合规格书要求,可直接用于量产电路,无需额外筛选。
ARG06DTC4701凭借稳定的性能与高性价比,成为工业、通信、消费电子等领域的常规选型电阻。

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.
