AR05BTC4002 薄膜贴片电阻产品概述

一、产品核心定位与封装规格

AR05BTC4002是Viking(光颉)推出的工业级精密薄膜贴片电阻,针对对阻值精度、温度稳定性要求严苛的场景设计。采用行业通用的0805封装(英制尺寸,对应公制2012,即2.0mm×1.2mm),适配自动化表面贴装工艺,支持高密度PCB布局,可满足小型化电子设备的设计需求。

二、电气性能参数详解

该产品核心电气参数覆盖高精密、低漂移、宽适应的特点,具体如下:

  • 阻值与精度:标称阻值40kΩ(电阻标识“4002”对应“40×10²Ω”),精度±0.1%——可直接用于精密电路的基准分压、分流环节,避免误差累积影响系统性能(如数字仪表的采样精度)。
  • 功率与电压:额定功率100mW,最大工作电压100V——在低功耗信号调理、中等电平电路中无需额外降额设计,稳定支持常规模拟/数字电路的信号传输。
  • 温度系数(TCR):±25ppm/℃——温度每变化1℃,阻值变化量仅为25×10⁻⁶×40kΩ=1Ω,在宽温范围内阻值漂移极小,是极端环境下电路稳定的关键保障。

三、环境适应性与可靠性

  1. 宽温工作范围:支持-55℃+155℃环境温度,覆盖工业级(-40℃+85℃)、汽车级(部分高温场景)甚至户外恶劣工况,可用于车载电子、工业自动化等对温度敏感的领域。
  2. 薄膜工艺优势:采用镍铬合金薄膜技术(Viking核心工艺),相比碳膜、金属氧化膜电阻,具有低噪声、无电感效应、长期稳定性高的特点,适合高频电路(如射频前端)和精密测量场景。
  3. 可靠性认证:符合RoHS、REACH环保标准,耐回流焊温度冲击(峰值260℃下性能无衰减),抗潮湿、抗硫化(部分批次特性),可满足5年以上长期运行需求。

四、典型应用场景

该产品因高精密、宽温稳定的特性,广泛应用于中高端电子设备:

  1. 精密测量仪器:数字万用表、示波器的校准电路,利用±0.1%精度实现准确的信号采样与显示;
  2. 通信设备:基站射频前端的信号调理、滤波器匹配网络,低噪声薄膜电阻减少信号失真;
  3. 工业自动化:PLC模拟量输入模块、温度传感器放大电路,宽温范围适配车间/户外工况;
  4. 医疗电子:监护仪、输液泵的生理信号调理电路,高稳定性保证检测结果的准确性;
  5. 汽车电子:车载导航、车身控制模块的低功耗电路,适配汽车-40℃~+125℃的工作环境。

五、品牌与选型价值

Viking(光颉)作为全球知名被动元件厂商,其薄膜电阻在一致性、可靠性上处于行业前列:

  • 生产采用激光微调技术,批量产品阻值偏差控制在±0.1%以内,无需额外筛选;
  • 提供完整的可靠性测试报告(如温度循环、湿热老化),满足客户ISO/TS16949、IEC等认证需求;
  • 供货周期稳定,支持小批量定制(如特殊TCR要求),适配不同客户的研发与生产节奏。

综上,AR05BTC4002是一款兼顾精密性、稳定性与环境适应性的薄膜贴片电阻,是替代普通电阻、提升电路性能的优选方案,可满足中高端电子设备的严苛设计要求。

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
