4D02WGJ0472TCE 产品概述

一、产品简介

4D02WGJ0472TCE 是 UNI-ROYAL(厚声)出品的一款贴片排阻网络,封装尺寸 2.0 × 1.0 mm(对应 0402 单体尺寸等级),8 引脚、4 支电阻(8P4R)。每只电阻标称阻值 4.7 kΩ,公差 ±5%,单个元件额定功率 62.5 mW,温度系数(TCR)为 ±200 ppm/℃。该器件适合对体积、重量和焊接一致性有较高要求的高密度 PCB 设计。

二、主要特性

  • 阻值:4.7 kΩ(4 阵列)
  • 精度:±5%(常规工业级精度)
  • 单个功率:62.5 mW(请按 PCB 热阻和环境温度适当降额使用)
  • 温度系数:±200 ppm/℃
  • 引脚/通道数:8 引脚、4 路电阻(共用或独立端口,布局为 8P4R)
  • 封装:SMD,外形 2 × 1 mm(0402 等效阵列封装)
  • 品牌:UNI-ROYAL(厚声)

三、典型应用场景

  • 数字电路的下拉/上拉电阻组(例如微处理器或 FPGA 的多信号线)
  • 多路信号的统一匹配与偏置电路(如按键矩阵、行列拉高/拉低)
  • 低功耗传感器网络中分立阻值需求场合
  • 空间受限的便携设备、智能终端、消费电子与工业控制板的阻值阵列替代分立器件

四、PCB 设计与焊接建议

  • 推荐焊盘布局按照供应商建议的 2.0 × 1.0 mm 封装尺寸设计,并在焊盘两端留足热容与沉铜面积以利焊接质量。
  • 由于单体功率仅 62.5 mW,应避免在靠近大功耗器件或受限散热区域直接并排密集放置,必要时增加散热铜箔或散热通孔。
  • 常规无铅回流建议:遵循元件和焊料厂商的回流温度曲线(典型峰值 240–260℃),避免多次高温循环。具体回流曲线以厂家资料为准。
  • 清洗时注意使用与封装兼容的清洗剂,避免化学物质侵蚀标识或粘结材料。

五、可靠性与使用注意

  • 温度系数 ±200 ppm/℃ 表明随环境温度变化阻值会发生线性漂移,设计时需考虑温漂影响,关键精度场合应选更低 TCR 的类型。
  • 建议对工作电流进行降额设计:在长期运行或高环境温下,尽量使实际功耗远低于 62.5 mW(例如建议在 50% 以下工作点以提高寿命)。
  • 若电路涉及高压或高绝缘要求,请在选型前确认该器件的最大工作电压、绝缘电阻及电气隔离规范,必要时联系厂商索取完整数据表与可靠性测试结果。
  • 机械应力(如直接弯折、强力刮擦)可能引起焊点或封装损伤,贴装过程中请按回流工艺与贴装机设定操作。

六、验收与测试提示

  • 进货验收可采用万用表或阻值测量仪对每通道阻值与并联/开路状态进行抽检,注意在测量时避免并联电路干扰。
  • 做温度漂移测试可在额定温度范围内测量阻值变化,验证 TCR 是否在 ±200 ppm/℃ 规范内。
  • 出货与维修时保留样品以便进行故障追踪与材料分析。

七、采购与技术支持

为确保最终应用可靠性,采购时请索取完整数据手册(Datasheet)、回流焊接曲线、焊盘建议图和环境/可靠性测试报告。对于特殊应用(高压、高精度或关键安全场合),建议与 UNI-ROYAL 技术支持确认器件的完整电气与环境规格。

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
