0603WAF2492T5E 产品概述

一、产品简介

0603WAF2492T5E 是 UNI-ROYAL(厚声)系列的厚膜贴片电阻,阻值 24.9kΩ,精度 ±1%,额定功率 100mW,标准 0603 封装(约 0.06" × 0.03",约 1.6mm × 0.8mm)。该型号适用于空间受限的表面贴装电路,兼顾体积和性能,常用于消费类电子、通讯设备、测量仪表及传感器接口等场合。

二、主要参数与特性

  • 电阻类型:厚膜电阻
  • 阻值:24.9kΩ
  • 精度:±1%(等级较高,适合精密阻值要求场合)
  • 额定功率:100mW(典型室温条件下)
  • 最高工作电压:75V(器件最大标称工作电压)
  • 温度系数(TCR):±100 ppm/℃(约 0.01%/℃,温度变化对阻值的影响可控)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0603(贴片)
  • 品牌:UNI-ROYAL(厚声)

三、电气性能说明

  • 温度系数 ±100 ppm/℃ 表示每升高 1℃,阻值约变化 0.01%,例如温度上升 80℃ 时阻值变化约 0.8%,需在精度预算中考虑温漂影响。
  • 功率与电压关系:在额定功率 0.1W 条件下,理论最大允许电压约 V = sqrt(P·R) ≈ sqrt(0.1×24900) ≈ 49.9V。尽管器件标称工作电压为 75V,但在实际连续工作时应以功率限制(约 49.9V)为准以避免过热。
  • 在高温环境下,器件需按厂商数据进行功率降额处理(详见厂方热功率降额曲线)。

四、封装与焊接建议

  • 0603 体积小,焊接时应控制热循环,推荐遵守 J-STD-020 回流焊规范,峰值温度一般不超过 260℃,并控制加热时间以避免过热。
  • 推荐采用自动贴片与回流工艺,焊盘设计请参考厂商推荐样式以保证焊接可靠性与阻值稳定。
  • 避免在焊接或后处理时对元件施加机械挤压或强烈弯曲,贴装后若需清洗,建议使用对厚膜电阻安全的清洗剂并缩短浸泡时间。

五、典型应用

  • 精密分压、电压检测与基准回路
  • 信号链偏置与拉升/拉低电阻(pull-up/pull-down)
  • 增益设定与反馈网络(运放、ADC 前端)
  • 消费电子、移动设备、通讯设备、仪器仪表及工业控制电路

六、可靠性与储存

  • 工作温度范围宽(-55℃ ~ +155℃),适用工业级应用环境。
  • 储存时避免潮湿、高温及强酸碱环境,建议原包装储存于干燥、常温条件下;长时间存放后如需回流焊接,宜按回流曲线进行预热以排除吸湿风险。
  • 对于关键长期可靠性需求(如航天、医疗等),建议依据具体应用做额外的温度循环与湿热测试验证。

七、订购与注意事项

  • 型号:0603WAF2492T5E,品牌 UNI-ROYAL(厚声)。
  • 常见包装形式为卷带(Tape & Reel),便于 SMT 自动化生产;具体卷盘尺寸与数量请参照供货单或与供应商确认。
  • 选型时请综合考虑阻值精度、温漂、功率与工作电压的匹配,若电路中存在较高瞬态电压或长时间大功率耗散场景,应选择更高功率或更高额定电压的器件以提高可靠性。

如需该型号的详细数据表(包括降额曲线、焊盘建议和可靠性测试数据),可向供应商索取原厂 Datasheet 以便设计验证与量产使用。

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
