ARG05DTC2502 产品概述

一、产品简介

ARG05DTC2502 是 Viking(光颉)推出的一款高稳定性薄膜表面贴装电阻,封装为 0805(约 2.0 mm × 1.25 mm),阻值 25 kΩ,额定功率 125 mW,精度 ±0.5%。采用先进的薄膜工艺制造,针对需要高线性、低温漂与高可靠性的精密电子场合进行了优化,尤其适用于医疗设备与测试/测量设备等对元件一致性和长期稳定性要求高的行业。

二、主要特性

  • 先进薄膜技术,具有良好的线性与低噪声特性。
  • 精度高:±0.5% 宽松度控制,适合精密分压与信号处理电路。
  • 低温度系数:±25 ppm/℃,在温度变化场合保持阻值稳定。
  • 额定功率:125 mW(表面贴装 0805 封装),小型化并可实现自动化贴装。
  • 工作电压:最高 150 V,适合中等电压应用。
  • 宽工作温度范围:-55℃ 至 +155℃,能够满足绝大多数工业与医疗环境。
  • 封装为 SMD/0805,兼容自动贴装与回流焊工艺,便于大规模生产与组装。

三、电气参数(关键参数)

  • 阻值:25 kΩ
  • 阻值公差:±0.5%
  • 功率额定值:125 mW(0805 封装)
  • 最高工作电压:150 V
  • 温度系数(TCR):±25 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 可提供的阻值范围(系列):从 ohm 级至 2.49 MΩ,便于在同一系列中选型配套

四、环境与可靠性

ARG05DTC2502 设计用于对长期稳定性与温度变化敏感的应用场景。薄膜工艺在抗湿热、抗氧化及长期漂移方面优于普通碳膜电阻,常见可靠性特点包括:

  • 抗热冲击与回流焊适应性好(推荐严格按建议的回流曲线进行,避免超出规范的高温与长时间浸泡)。
  • 长期阻值漂移小,适合精密测量与校准电路。
  • 在 -55℃~+155℃ 大温度范围内仍保持较小的阻值变化(受 TCR 限制)。
    (注:实际可靠性数据及资格认证请参阅厂方测试报告或与销售工程师确认。)

五、封装与安装建议

  • 封装:0805(公制 2012)——占板面积小,适合高密度布板。
  • 推荐贴装工艺:与其它 SMD 器件相同,采用自动贴装(SMT)与回流焊工艺以保证批量一致性。
  • 焊接注意事项:避免过高的回流峰值温度与过长保温时间;建议参考 Viking 提供的回流曲线与焊接工艺规范。
  • 机械应力:在 PCB 设计与夹具固定时避免对元件施加过大的弯曲或剪切力,以免引起导电膜开裂或引线脱落。

六、典型应用场景

  • 医疗设备:生理信号放大、传感器前端、精密分压与参考网络等需要高稳定性的电路。
  • 测试与测量设备:校准电路、阻抗网络、精密输入衰减与滤波器中对阻值稳定性要求较高的节点。
  • 工业自动化与控制:传感器接口、阻值基准与精密采样回路。
  • 其他需要低温漂、高可靠性的电子系统。

七、选型与订购建议

  • 若电路对温漂与长期稳定性有更高要求,可在同系列中选择更低 TCR 或更紧公差的型号(如有供应)。
  • 对于高电压与高功率工况,请确认最大工作电压(150 V)与在实际工作温度下的功率降额要求,必要时选用更大封装或更高功率等级的器件。
  • 订购时请注明完整型号 ARG05DTC2502、数量、包装形式(卷带/盘装等)及任何特定烧录或筛选要求。
  • 如需可追溯的可靠性/认证资料(如医疗类认证)或定制阻值和公差,建议与 Viking(光颉)或其授权代理联系索取详细技术资料与样片测试支持。

总结:ARG05DTC2502 以其薄膜工艺、低 TCR、高精度与宽温度适应性,适合要求稳定性和可靠性的精密应用场合,尤其在医疗与测试/测量设备中具有良好适配性。若需更详细的电气与环境试验数据、回流焊曲线或样品评估建议联系供应商获取完整技术资料。

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
