AR03FTC2001是Viking(光颉)推出的0603封装精密薄膜贴片电阻,核心参数针对性强,具体如下:
该产品围绕精密性、稳定性、小型化三大核心设计,具体表现为:
采用薄膜工艺制备电阻体,相比厚膜电阻,阻值一致性更好、噪声更低,且温度系数更优——±25ppm/℃意味着温度每变化1℃,阻值偏差不超过0.0025%,宽温下仍能保持稳定性能。
±1%的精度等级,可避免因阻值误差导致的信号失真或电路性能下降,适配传感器信号调理、音频前置放大等精密场景。
-55℃+155℃的温度范围,超出常规工业级(-40℃+85℃),可适应高温环境(如汽车发动机舱、工业窑炉监测)或低温场景(如极地设备、户外通信基站)。
0603封装体积小巧,适合高密度PCB设计(如智能手机主板、小型PLC模块),能有效节省电路空间,提升产品集成度。
结合参数特性,AR03FTC2001可广泛应用于以下领域:
该产品的可靠性设计针对实际应用挑战,具体表现为:
以温度变化210℃(-55℃→+155℃)为例,阻值最大偏差为210℃×25ppm/℃=±0.525%,仍在±1%精度范围内,确保宽温下电路性能无明显波动。
0603封装符合贴片焊接标准,支持回流焊、波峰焊工艺,焊接可靠性高;且产品符合RoHS环保要求,无铅无镉,适配绿色制造。
实际使用需同时满足:①耗散功率≤62.5mW;②工作电压≤50V。例如,当阻值2kΩ时,最大允许电压为≈11.18V(对应电流≈5.59μA),若电压超过50V,需严格限制电流(≤1.25mA),避免绝缘损坏。
AR03FTC2001是一款高性价比精密薄膜贴片电阻,以±1%精度、±25ppm/℃温度系数、宽温范围和小型化封装为核心优势,可满足精密信号处理、工业控制、消费电子等多领域需求,是设计小型化、高稳定性电路的理想选择。

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.
