ARG03FTC3161 产品概述

一、产品简介

ARG03FTC3161 是 Viking(光颉)品牌的一款高稳定性贴片薄膜电阻,封装为 0603(公制约 1.6 mm × 0.8 mm),标称阻值 3.16 kΩ,公差 ±1%,功率等级 100 mW,额定工作电压 75 V,温度系数(TCR)典型值为 ±25 ppm/℃,工作温度范围 -55 ℃ 至 +155 ℃。该系列以薄膜工艺制造,兼具低噪声、高精度与良好长期稳定性,适用于要求精确阻值和温度稳定性的电子电路。

二、主要特性

  • 阻值:3.16 kΩ(3160 Ω),适用于精密分压、偏置与反馈网络。
  • 精度:±1%,适合精密测量与控制场合。
  • 功率:100 mW(封装限制),适用于低功耗电路。
  • 额定工作电压:75 V(制造商标称值);实际应用时应以功率限制为准(见注意事项)。
  • 温度系数:±25 ppm/℃,保证在温度变化下阻值稳定性优异。
  • 工作温度:-55 ℃~+155 ℃,适应工业级温区。
  • 工艺:薄膜电阻,具有低噪声、低漂移和良好的可重复性。
  • 封装:0603 表面贴装,适用于高密度 PCB 设计与自动回流贴装工艺。
  • 环保:符合 RoHS 要求(如需认证证书,请向供应商索取)。

三、性能与注意事项

  1. 功率与电压关系:标称功率为 100 mW,但在不同阻值下,电压-功率关系需满足 P = V^2 / R。对 3.16 kΩ 电阻,按功率限值计算得到的最大直流电压约为 17.8 V(sqrt(0.1 W × 3,160 Ω) ≈ 17.8 V)。因此在实际电路设计中,应以更严格的限制(即较小的 V)为准,避免仅依据额定工作电压而使器件过载。
  2. 温度降额:在高温环境下器件需进行功率降额处理。常见的降额曲线为在 +70 ℃ 后开始线性降额,至最高工作温度(+155 ℃)降至 0 W。具体降额规则应参考厂方数据表。
  3. 焊接工艺:建议采用符合 IPC 标准的无铅回流焊工艺,峰值温度一般不超过 260 ℃,且热循环应符合元器件耐焊接规范。
  4. 机械与环境耐受性:薄膜电阻对湿热、温度循环、振动和冲击具有良好可靠性,但建议遵照厂方提供的可靠性试验报告进行苛刻环境下的应用评估。

四、典型应用场景

  • 精密模拟电路:高精度电阻网络、放大器反馈、阻抗匹配。
  • 测量与传感接口:传感器偏置、滤波和电桥电路(如桥式测量)。
  • 通信与控制设备:精密分压、参考网络、微控制器外围电阻。
  • 工业与汽车电子(在符合温度与震动要求下):要求长期稳定性的电路节点。

五、封装与 PCB 设计建议

  • 封装尺寸(典型):0603 封装体积约 1.6 mm × 0.8 mm,厚度依制程不同约 0.35–0.55 mm。请以实际样片为准。
  • 贴装建议:推荐采用与 IPC 标准相符的焊盘和焊膏印刷尺寸,确保焊点均匀、焊接可靠。推荐在 PCB 设计中参考厂方推荐的 land pattern 或 IPC-SM-782 指南。
  • 放置与回流:为减小热应力,建议在回流焊过程中合理安排相邻器件的焊接顺序并控制峰值温度与时间。

六、选型与采购注意

  • 样片与批次一致性:薄膜电阻具有良好的复制性,但批次间仍存在微小差异。关键应用建议先行样件确认并保留批次记录。
  • 包装与数量:常见为带卷(tape & reel)包装,便于 SMT 自动化贴装。具体卷盘数量、出货形式与最低起订量请咨询供应商或授权分销商。
  • 技术支持:如需完整数据表(含尺寸图、降额曲线、可靠性测试结果)、认证文档或定制化阻值/公差范围,建议联系 Viking(光颉)或指定代理商获取详尽资料。

总结:ARG03FTC3161 以薄膜工艺提供高精度、低噪声与良好温度稳定性的 0603 贴片电阻,适用于对阻值稳定性与长期可靠性有较高要求的精密电子应用。设计时需留意功率-电压限制与温度降额,以确保长期可靠运行。

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
