AR03FTDX3503N 为 Viking(光颉) 系列贴片薄膜电阻,阻值 350kΩ,公差 ±1%,封装 0603(约 1.6 mm × 0.8 mm)。额定功率 100 mW,温度系数(TCR)典型 ±50 ppm/℃,工作温度范围为 -55℃ 至 +155℃。该元件以薄膜工艺制成,适用于对温漂、稳定性和噪声有较高要求的小型化电路设计。
薄膜工艺使得 AR03FTDX3503N 在低噪声和低温漂方面明显优于常规厚膜电阻。1% 的精度配合 ±50 ppm/℃ 的 TCR,适合做高稳定性的阻值参考或精密分压。由于 0603 尺寸限制,长时间连续承载接近额定功率时需关注散热与环境温度影响;在高温工况下建议按厂商热降额曲线进行功率降额以保证可靠性。
结语:AR03FTDX3503N 以其薄膜工艺、优良的温漂特性与 0603 小尺寸,适合精密、体积受限及宽温应用场景。在具体使用前,请参考厂家完整规格书和焊接指南以确保设计与可靠性满足要求。

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.
