AR03FTC1004是光颉(Viking) 推出的0603封装薄膜贴片电阻,针对小功率、高精度电路场景设计,核心参数如下:
该产品基于薄膜电阻工艺,阻值稳定性优于厚膜电阻,适合对精度和长期可靠性有要求的场景。
高精度与低温度漂移
±1%的阻值精度可满足大多数信号调理、分压电路的需求;±25ppm/℃的温度系数意味着,当环境温度从-55℃变化至+155℃(温差210℃)时,阻值最大变化量仅为:
1MΩ × 25ppm/℃ × 210℃ = 5.25Ω(约±0.0005%),可忽略温度波动对电路信号的影响。
小功率与宽电压兼容
62.5mW额定功率适配低功耗电路(如电池供电设备),同时50V最大工作电压覆盖了多数工业控制、汽车电子的信号电压范围(需注意:实际使用需同时满足功率≤62.5mW和电压≤50V,优先以电压限制为准,因V=50V时功率仅2.5mW,远低于额定功率)。
宽温工作可靠性
-55℃+155℃的工作温度范围,覆盖了汽车发动机舱(-40℃+125℃)、工业现场(-20℃~+85℃)等极端环境,无需额外降额设计即可稳定工作。
0603封装具备以下优势:
AR03FTC1004因体积小、精度高、宽温可靠,广泛应用于:
该产品兼顾精度、体积与可靠性,是小功率高精度电路的优选元件。

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.
