AR03FTDX3503N 产品概述

一、产品简介

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。

二、主要特性

  • 阻值:350 kΩ;公差:±1%;
  • 封装:0603(1608 metric),适配高密度表贴布局;
  • 功率额定:0.1 W(100 mW),适用于低功耗、精密信号通道;
  • 温度系数:±50 ppm/℃,温漂小、温度依赖性低;
  • 工作温度:-55℃ ~ +155℃,适应宽温范围应用;
  • 薄膜结构:低噪声、优秀的长时间稳定性与重复性。

三、典型应用

  • 精密模拟电路(电阻分压、偏置网络、增益设定);
  • 传感器信号调理、滤波器和采样电路;
  • 通信设备与测试测量仪器的阻值精确要求场合;
  • 工业控制与宽温环境下的电子产品(如需车规级认证,请咨询厂家)。

四、电气与可靠性说明

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。

五、焊接与使用建议

  • 兼容常见无铅回流焊工艺,推荐参考 J-STD-020 回流曲线进行焊接温度控制;避免超过器件所能承受的最高峰值温度;
  • 贴装时避免对元件施加过大机械应力(如强烈弯曲或挤压),以防端接破裂或内部损伤;
  • 常规清洗剂和温和溶剂一般可用,避免强酸强碱及含氟腐蚀性化学品长期接触;
  • 在高湿或腐蚀性环境下建议采取封装保护或特殊处理。

六、封装与订购信息

  • 标准包装形式为卷带(Tape & Reel),适合贴片机自动贴装;
  • 型号:AR03FTDX3503N;品牌:Viking(光颉);
  • 选型时请确认是否需要机加工、筛选或特殊老化/配对服务,如需批量、样品或认证资料,请联系供应商索取数据手册与可靠性试验报告。

七、选型注意事项

  • 若电路中存在高电压跨接或脉冲能量,应评估电压系数与最大工作电压,必要时选择更低阻值或更大封装的器件以降低自热;
  • 如需车规级稳定性或更小 TCR,可咨询厂方是否有 AEC-Q 等级或 TCR 更优的对应系列;
  • 对温度敏感或长期高可靠性应用,建议查看并依据厂方的功率降额曲线及寿命评估数据进行设计裕量。

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
