ARG05BTC4992 产品概述

一、产品简介

ARG05BTC4992 是 Viking(光颉) 系列高精度薄膜贴片电阻,封装为 0805(约 2.03 mm × 1.27 mm),标称阻值 49.9 kΩ,公差 ±0.1%,额定功率 125 mW,最高工作电压 150 V,温度系数(TCR)±25 ppm/℃,工作温度范围 -55℃ 至 +155℃。该器件以稳定性好、噪声低、长期漂移小为特点,适合对精度和温度稳定性有较高要求的电子系统。

二、主要技术参数

  • 阻值:49.9 kΩ
  • 精度:±0.1%
  • 功率:125 mW(额定)
  • 最高工作电压:150 V
  • 温度系数:±25 ppm/℃(典型)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0805(贴片)
  • 制程:薄膜电阻(低噪声,高稳定性)
  • 品牌:Viking(光颉)

三、核心特性与优势

  • 高精度:±0.1% 的阻值公差,可用于精密电路的精确分压与参考应用。
  • 良好温漂:±25 ppm/℃ 的低温度系数,保证在宽温度范围内阻值变化小,适合计量、传感器前端等对温漂敏感的场合。
  • 稳定可靠:薄膜工艺提供更低的长期漂移与更好的电气稳定性,寿命和重复性优于普通厚膜产品。
  • 低噪声:薄膜结构本征噪声低,适合放大器、滤波器等对噪声要求高的模拟电路。
  • 通用封装:0805 外形兼容主流 SMT 贴装工艺,便于自动化生产与流片制造。

四、典型应用场景

  • 精密电阻分压器与参考网络(ADC/DAC 输入、比较器参考)
  • 仪器仪表与测试测量设备(数据采集、恒流源、桥路)
  • 模拟信号处理(滤波、放大器偏置、增益设定)
  • 工业与汽车电子中需要高温稳定性的电路(注意热降额)
  • 医疗电子与通讯设备中对低噪声与高可靠性要求的场合

五、使用与焊接建议

  • 兼容常规回流焊工艺,建议遵循元件制造商提供的回流曲线,避免长时间高温暴露以减少漂移。
  • 在高温环境下应考虑功率降额:尽量避免在接近最高工作温度下长时间以额定功率工作,必要时在设计中预留裕量或通过散热/布局降低元件温升。
  • 贴装时注意 PCB 板面焊盘设计与回流温度控制,以确保焊点可靠性与电阻性能稳定。

六、可靠性与包装

  • 薄膜工艺在温度循环、湿热与机械冲击等项目上通常表现良好,但具体可靠性数据(如寿命测试、湿热等级、冲击/振动)请参照 Viking(光颉)出具的检验报告或向供应商索取。
  • 常见包装为卷带(Reel)形式,适用于贴片机自动上料;订购时请注明卷带宽度与单位卷径等要求。

七、选型与注意事项

  • 若电路中存在较高脉冲能量或瞬态电压,确认 150 V 的最高工作电压能否满足瞬态需求(必要时加保护元件或选择更高额定电压的电阻)。
  • 对温漂和长期稳定性有更严苛要求时,可与制造商确认更多批次一致性与热稳定试验数据。
  • 在设计高精度参考网络时,建议配合低漂移、电阻温度匹配良好的其他元件,并在布局上保证热源隔离与散热一致性。

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
