AR05FTC1002 贴片薄膜电阻产品概述

AR05FTC1002是Viking(光颉) 推出的一款0805封装精密贴片薄膜电阻,针对工业级宽温、高阻值精度需求设计,广泛适用于信号调理、阻抗匹配等场景,是普通厚膜电阻的升级替代方案。

一、产品基本定位与标识

该电阻属于薄膜电阻类别,采用真空镀膜工艺形成均匀电阻膜层,相比厚膜电阻具备更高精度和更低温度漂移。型号核心标识对应:

  • “AR05”:0805封装(英制尺寸0.08″×0.05″,公制约2.0mm×1.25mm);
  • “FTC”:薄膜电阻(Film Type);
  • “1002”:阻值编码(前三位100×10²=10kΩ)。

二、核心电气性能参数

1. 阻值与精度

额定阻值为10kΩ,精度等级达**±1%**,可满足运算放大器反馈网络、精密分压电路等对阻值匹配误差≤1%的场景需求。

2. 功率与电压规格

  • 额定功率:100mW(25℃连续工作上限);
  • 工作电压:100V(短期过压限制),需注意:连续工作电压需结合功率计算——由(P=U^2/R)得(U=\sqrt{0.1W×10kΩ}≈31.6V),实际连续电压应不超过32V,避免过功率损坏。

3. 温度系数(TCR)

温度系数为**±25ppm/℃**,表示每变化1℃,阻值漂移量为额定阻值的25×10⁻⁶。以-55℃~+155℃温差210℃计算,阻值最大漂移仅0.525%,远优于普通厚膜电阻(通常±100ppm/℃以上)。

4. 工作温度范围

覆盖**-55℃~+155℃**,符合工业级宽温标准,可在极端低温(北方户外设备)或高温(靠近热源模块)环境下稳定工作。

三、封装与物理特性

采用0805表面贴装封装,具备三大优势:

  • 体积紧凑:仅2.0mm×1.25mm×0.5mm(典型厚度),大幅节省PCB布局空间,适配高密度电路;
  • 工艺兼容:支持回流焊、波峰焊等自动化贴装,生产效率高;
  • 基片可靠:高导热陶瓷基片可快速散发热量,降低电阻自身温度,提升长期稳定性。

四、典型应用场景

  1. 精密模拟电路:运算放大器反馈/偏置网络、传感器信号调理电路;
  2. 工业控制模块:PLC输入输出电路、电机驱动电流检测电阻;
  3. 通信设备:射频/中频阻抗匹配网络、电源监测电路;
  4. 消费电子:高端音频设备音调控制、智能家电传感器接口;
  5. 汽车电子辅助电路:非高温区域车身控制模块(BCM)信号调理。

五、可靠性与品质保障

Viking光颉针对该电阻做了多重可靠性设计:

  • 薄膜工艺稳定性:真空镀膜膜层均匀,长期阻值漂移≤0.1%/1000小时;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无卤;
  • 可靠性测试:通过温度循环(-55℃~+155℃,500次)、湿度测试(85℃/85%RH,1000小时)、功率负载测试(100%额定功率,1000小时),满足IEC 61041国际标准。

六、使用注意事项

  1. 功率降额:建议实际工作功率不超过额定功率的70%(70mW),避免过热导致阻值漂移;
  2. 焊接工艺:回流焊峰值温度≤260℃(时间≤10秒),波峰焊温度≤245℃(时间≤5秒),防止基片开裂;
  3. 静电防护:薄膜电阻对ESD敏感,生产/测试需佩戴防静电手环,使用防静电包装;
  4. 电压限制:连续工作电压≤32V,短期脉冲电压≤100V,禁止长期超额定功率。

综上,AR05FTC1002以高精密、宽温稳定、小体积的特点,成为工业级精密电路的可靠选择,覆盖多领域应用需求。

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
