AR05BTCW2701产品概述

一、产品基本信息

AR05BTCW2701是台湾光颉(Viking)电子推出的精密贴片薄膜电阻,型号命名直接映射核心特性:

  • “AR”为光颉薄膜电阻系列标识;
  • “05”对应0805英制贴片封装;
  • “BTC”代表薄膜工艺+高精密级别;
  • “W2701”表示标称阻值2.7kΩ(270×10¹)。

作为光颉电阻产品线中的高性价比型号,该产品兼顾小体积、高稳定与宽温适应性,适用于对阻值精度和环境可靠性要求苛刻的电子场景。

二、核心电气参数详解

该型号围绕精密性与稳定性设计,关键参数可支撑多数中小功率精密电路需求:

  • 阻值与精度:标称2.7kΩ,精度±0.1%——属于“高精密电阻”范畴,可避免电路中基准电压、分压比、信号衰减的偏差,满足示波器、医疗设备等对测量精度的要求;
  • 功率与电压:额定功率125mW,最大工作电压150V——适配信号处理、低功耗控制模块等中小功率场景,电压上限覆盖常规直流/低频交流应用,无需额外降额;
  • 温度系数(TCR):±25ppm/℃——薄膜工艺使温度漂移远低于碳膜/金属膜电阻,环境温度变化100℃时,阻值漂移仅0.25%,结合±0.1%精度,宽温下仍保持稳定。

三、封装与物理特性

采用0805贴片封装(英制2.032mm×1.27mm,公制2012),符合国际通用标准:

  • 尺寸紧凑:适配智能手机、便携式测试仪器等小型化设备的高密度贴装,节省PCB空间;
  • 贴装兼容:支持自动化SMT生产线(回流焊、波峰焊),焊接工艺成熟,量产一致性好;
  • 结构可靠:陶瓷基底+真空镀膜(镍铬/钌系)+保护膜设计,耐磨损、抗潮湿、抗静电,延长使用寿命。

四、环境适应性与可靠性

该产品覆盖工业级宽温范围,可靠性突出:

  • 工作温度:-55℃+155℃——远超民用级(0℃70℃),可适应户外通信基站、工业控制箱、车载模块等极端环境;
  • 长期稳定:薄膜工艺避免金属膜电阻的阻值老化,1000小时高温负载测试后,阻值变化率≤0.05%,适合长期连续工作;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅焊接兼容,满足绿色电子设计要求。

五、典型应用场景

结合参数特性,AR05BTCW2701广泛用于以下领域:

  1. 精密测试仪器:示波器、万用表的基准电路、分压校准模块,确保测量精度;
  2. 通信设备:基站射频前端信号衰减网络、光纤收发器偏置电路,利用低噪声特性提升信号质量;
  3. 工业控制:PLC模块、传感器信号调理电路,适应车间高低温与湿度变化;
  4. 医疗电子:监护仪、血糖仪的信号放大/滤波电路,满足医疗设备的可靠性要求;
  5. 消费电子:高端音频解码器参考电压电路、智能手机电源管理模块,兼顾小体积与性能。

六、品牌与工艺优势

光颉(Viking)作为全球被动元件厂商,在薄膜电阻领域有20余年经验:

  • 工艺成熟:自主真空镀膜技术使批量产品精度偏差≤±0.05%,优于行业标准;
  • 品质管控:每批次全参数测试(阻值、TCR、功率负载、温度循环),不良率≤10ppm;
  • 供应链稳定:产能充足,可满足中小批量到大规模量产,交货周期短。

总结而言,AR05BTCW2701是一款“小体积、高精度、宽温稳定”的贴片薄膜电阻,以高性价比适配多种精密电子场景,是工程师优化电路性能与可靠性的理想选择。

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
