ARG05FTC4991 产品概述

一、产品简介

ARG05FTC4991 是 Viking(光颉)系列的贴片薄膜电阻,采用0805(2012公制,约2.0 × 1.25 mm)封装,阻值 4.99 kΩ,精度 ±1%,额定功率 125 mW。此款薄膜电阻以低温度系数和良好的长期稳定性为主要卖点,适合对阻值精度与温漂有较高要求的小体积表面贴装电路。

二、主要参数

  • 电阻类型:薄膜电阻(Metal Film)
  • 阻值:4.99 kΩ
  • 精度:±1%(B级)
  • 额定功率:125 mW(室温基准)
  • 最高工作电压:150 V
  • 温度系数(TCR):±25 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0805(SMD)
  • 品牌:Viking(光颉)

三、性能与特点

  • 高稳定性:薄膜工艺保证了良好的长期阻值稳定性和低噪声特性,适合精密测量与信号链应用。
  • 低温漂:±25 ppm/℃ 的低 TCR 在温度变化环境中能维持较小的阻值漂移,利于高精度电路设计。
  • 小型化:0805 封装兼顾体积和功率承载,适合集成度较高的现代 PCB 布局。
  • 宽温区工作:可在工业级温度范围内运行,适合工业与通信类设备。
  • 兼容 SMT 工艺:适合回流焊贴装,便于高速贴装与规模化生产。

四、典型应用

  • 精密电阻网络与电压分压器
  • 传感器前端与信号调理电路
  • 工业控制、通信设备与仪器仪表
  • 消费电子与电源管理模块中对精度与稳定性有要求的场合

五、装配与使用建议

  • 回流焊兼容:可采用常规回流焊工艺进行贴装,建议按制造商焊接曲线和 PCB 热设计要求进行热降额考虑。
  • 功率降额:在高工作温度或受限散热条件下,应遵循热功率降额原则,避免长期在额定功率附近工作以延长寿命。
  • PCB 布局:为保证散热与测量精度,建议合理安排焊盘面积与热通道,避免邻近大热源。
  • 测试与选型:对关键应用建议在目标环境中进行温度循环与老化测试,验证长期漂移与可靠性。

六、存储与采购建议

  • 建议按防潮包装储存,避免长时间暴露于高湿环境;如为卷带供货,请在保质期内使用完毕。
  • 如需 RoHS、REACH、或更多可靠性测试报告(如寿命、耐焊接性),请向供应商或代理商索取相关文件。
  • 推荐订购信息示例:ARG05FTC4991 — Viking(光颉) 0805 薄膜电阻 4.99 kΩ ±1% 125 mW(卷带包装)。

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
