0402WGF4751TCE 产品概述

一、产品简介

0402WGF4751TCE 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,阻值 4.75 kΩ,精度 ±1%,额定功率 62.5 mW(1/16W),最大工作电压 50 V。温度系数(TCR)为 ±100 ppm/℃,工作温度范围 -55℃~+155℃,适用于对体积与精度兼顾的通用电子设计。

二、主要规格

  • 电阻类型:厚膜电阻
  • 阻值:4.75 kΩ(标称)
  • 精度:±1%
  • 额定功率:62.5 mW(0402)
  • 最大工作电压:50 V
  • 温度系数:±100 ppm/℃
  • 工作温度:-55℃ ~ +155℃
  • 封装:0402(典型外形约 1.0 mm × 0.5 mm,厚度视厂商而定)

三、产品特点

  • 小封装、高密度:0402 体积小,适合高密度贴片电路板。
  • 精度稳定:±1% 阻值满足多数模拟、数字电路阻值控制需求。
  • 宽温工作:可在-55℃至+155℃范围内长期工作,适合工业级环境。
  • 良好可焊性:厚膜工艺成膜均匀,适配标准回流焊工艺。

四、典型应用

  • 移动与便携设备的分压、负载与旁路网络
  • 消费电子、仪器仪表中的滤波与偏置电路
  • 工业控制、车载电子(参考车规认证)
  • 精密模拟与采集前端的限流与阻抗配合

五、装配与使用建议

  • 焊接工艺:兼容回流焊,参考峰值温度 260℃(按焊膏与工艺规范设定)。
  • 功率与热管理:在高环境温度或密集布板时应进行功率降额,避免长期接近额定功率。具体降额曲线请参见厂商数据手册。
  • 测量建议:对精度要求较高的场合建议在常温稳定后使用四线或恒流法测量阻值。
  • 储存与搬运:干燥、常温保存,避免潮湿与机械冲击;采用盘带包装以便贴装。

六、可靠性与订购信息

  • 常见可靠性试验:焊接热、温度循环、湿热与机械强度测试,满足一般工业级要求(具体合规性以出厂检验报告为准)。
  • 包装与订购:0402 常见卷带(tape & reel)包装,订购时请注明完整料号 0402WGF4751TCE、数量及包装方式,以便确认交货与可追溯性。

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
