AR03FTC2552 产品概述

一、产品简介

AR03FTC2552 是 Viking(品牌名:光颉)出品的一款高精度薄膜贴片电阻,封装为 0603(1.6 mm × 0.8 mm)。阻值为 25.5 kΩ,公差 ±1%,额定功率 62.5 mW,额定工作电压标称 50 V,温度系数(TCR)为 ±25 ppm/℃,工作温度范围 -55℃ 至 +155℃。本型号以薄膜工艺实现低噪声、低漂移和优良的长期稳定性,适合精密测量与高可靠性电子系统。

二、主要性能参数

  • 阻值:25.5 kΩ
  • 精度:±1%
  • 封装:0603(1.6 mm × 0.8 mm,贴片)
  • 功率额定:62.5 mW(环境与散热条件相关)
  • 标称工作电压:50 V(见注意事项)
  • TCR:±25 ppm/℃(典型薄膜电阻性能)
  • 工作温度:-55℃ ~ +155℃
  • 工艺:薄膜,噪声低、温漂小、长期稳定性好
  • 品牌:Viking(光颉)

三、关键特点与优势

  • 高精度:±1% 公差适合要求较高阻值准确性的信号链与分压电路。
  • 低温漂:±25 ppm/℃ 的 TCR 带来更稳定的阻值随温度变化特性,适合温度敏感应用。
  • 低噪声与高稳定性:薄膜工艺优于碳膜/厚膜,在精密测量、滤波及传感器前端表现优异。
  • 宽温度范围:-55℃ 至 +155℃,可用于严苛环境与工业/航天类应用。
  • 贴片小型化:0603 封装利于高密度 PCB 布局与自动化贴装。

四、使用与注意事项

  • 电压/功率限制:虽然标称工作电压为 50 V,但电阻承受功率不能超过 62.5 mW。按 P = V^2 / R 计算,从功率极限得到的允许最大直流电压 Vmax ≈ sqrt(0.0625 × 25500) ≈ 39.9 V。因此在实际设计中应以不超过功率限制的电压为准(取较严格限制),避免因过压导致过热或失效。
  • 温度升高与功率降额:环境温度升高时电阻的允许耗散会下降,应参考厂商的降额曲线(datasheet)并预留余量,保证长期可靠。
  • 焊接兼容性:适用于业界通用的无铅回流焊工艺(建议按照元件及 PCB 的回流规范执行)。小封装在焊接时应控制热冲击与回流温度曲线以避免应力损伤。
  • 贴装与储存:0603 为微小封装,建议使用自动贴装机或细尖镊子操作,避免机械碰撞或拉伸。按标准湿度敏感性(MSL)与 ESD 要求储存与搬运。

五、典型应用场景

  • 精密分压器与参考电路
  • 模拟前端放大器和滤波网络
  • 测量仪器、数据采集模块
  • 工业控制与传感器接口
  • 航空、通信等高可靠性电子系统

六、质量与可靠性

Viking 薄膜系列在工艺控制、筛选与出厂测试方面有严格流程,常见质量项目包括阻值与公差检验、TCR 测试、耐久性(功率与温度循环)以及焊接可靠性测试。建议在关键产品设计中参考厂商完整 Datasheet 与可靠性报告,并在量产前完成样件验证。

七、订购与包装

  • 型号:AR03FTC2552
  • 品牌:Viking(光颉)
  • 封装:0603
  • 常见包装:卷带(Tape & Reel),具体包装数量与出货方式可按客户需求确认。
  • 建议在订购时同时获取完整 Datasheet 以便确认降额曲线、焊接参数与可靠性数据。

如需进一步的电气特性曲线、降额图、回流焊温度建议或样品支持,可提供 PCB 使用场景与工作条件,我可根据实际情况给出更具体的设计建议。

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
