ARG05FTC4700 产品概述

一、主要参数

  • 型号:ARG05FTC4700(Viking / 光颉)
  • 电阻类型:薄膜贴片电阻(Thin Film SMD)
  • 阻值:470 Ω
  • 精度:±1%
  • 功率额定:125 mW(室温)
  • 额定工作电压:150 V(器件耐介电/绝缘参数)
  • 温度系数(TCR):±25 ppm/℃
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 封装:0805(2012公制,约2.0 mm × 1.25 mm)

二、性能与优势

ARG05FTC4700 采用薄膜工艺制成,较厚膜(碳膜、厚膜)电阻具有更低噪声、更小的温漂和更好的长期稳定性。±1% 的精度配合 ±25 ppm/℃ 的低温度系数,适用于需要中高精度和温度稳定性的电路设计。0805 小尺寸封装兼顾了PCB 布局密度与可焊性,适合自动化贴装与回流工艺。

三、电气与热特性说明

需注意额定功率与额定工作电压的关系:器件标称工作电压 150 V 表示元件的介电或耐压限制,而稳态允许的最大电压应受功率限制。稳态最大允许电压可由 Vmax = sqrt(P×R) 计算,代入 P=0.125 W、R=470 Ω,可得约 7.66 V。长期使用时请以功率限制为准,避免仅依据耐压值直接跨接高电压导致过热失效。

四、典型应用

  • 精密电阻分压、基准电路、传感前端(放大器输入)
  • 仪表、数据采集与测量设备中的信号处理电路
  • 通信设备与消费电子中要求稳定阻值的回路
  • 工业控制与测试设备(非车规或需额外认证的汽车应用除外)

五、封装、安装与可靠性

0805 封装适配主流贴片工艺,推荐使用工业级回流焊工艺。薄膜电阻具有良好的抗湿热性能与抗热循环能力,但仍需注意焊接峰值温度、焊膏类型及回流曲线,以免因过热或机械应力造成阻值漂移或裂纹。常见包装为卷带(Tape & Reel),便于自动贴装与生产线使用。制造商通常保证符合 RoHS 要求,客户可根据需要索取详细可靠性测试报告(如稳态负载寿命、湿热循环、温度冲击等)。

六、订购信息与使用注意事项

  • 订购编号:ARG05FTC4700,品牌 Viking(光颉)。
  • 选型时请核对批次和规格表,若用于关键或极端工况(高温、高湿、汽车电子等),建议向供应商确认是否具备相应认证或进行额外筛选。
  • 使用建议:布局时为提高散热和稳定性可避免在高功率密集区叠层放置,焊接后建议进行必要的电气测试验证阻值满足±1% 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
