0402WGJ0473TCE 产品概述

一、产品简介

0402WGJ0473TCE 是 UNI-ROYAL(厚声)系列的一款0402封装厚膜贴片电阻,标称阻值 47kΩ,精度 ±5%,额定功率 62.5mW。该器件以小尺寸、高密度贴装为目标,适用于需节省 PCB 面积和实现高元件密度的各类电子产品。厚膜工艺兼顾成本与可靠性,是通用型设计中常用的阻值选择之一。

二、主要技术参数

  • 型号:0402WGJ0473TCE
  • 品牌:UNI-ROYAL(厚声)
  • 阻值:47kΩ(473)
  • 精度:±5%(J)
  • 额定功率:62.5 mW(室温标称)
  • 最高工作电压:50 V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0402(约 1.0 mm × 0.5 mm,厚度依生产批次略有差异)
  • 工艺类型:厚膜电阻

三、产品特点

  • 小体积:0402 封装适合高密度表贴线路,节省 PCB 空间,利于轻薄化设计。
  • 成本效益高:厚膜工艺制造成本低,适合中低精度、大批量应用。
  • 稳定性良好:在常温及一般工业温度范围内具备可接受的电阻稳定性和一致性。
  • 通用性强:阻值与精度组合适用于分压、限流、偏置等多种电路功能。
  • 装配兼容:兼容常规表贴工艺与回流焊流程,便于 SMT 生产。

四、典型应用场景

  • 消费类电子:手机配件、耳机、可穿戴设备等需要高密度贴装的电路。
  • 工业与仪表:信号处理、偏置与分压电路(在功耗受限的场合)。
  • 通讯设备:射频前端的偏置电阻(依据功率与频率需求选型)。
  • 家电与控制类产品:检测、控制与滤波电路中的通用电阻元件。

五、设计与使用建议

  • 功率余量:0402 的额定功率仅 62.5 mW,建议在布局与电路设计中保留足够功率余量,避免长期满功率运行导致热应力累积。若电阻长期承受接近额定功率,应选用更大封装或并联/串联组合降额使用。
  • 温度与散热:在高温或高密度元件集中区域,应考虑热源布局,必要时通过加大 PCB 铜箔面积改善散热。
  • 焊接工艺:兼容常规无铅回流焊工艺;建议依据厂商推荐的回流曲线进行焊接,以保证可靠焊点与电阻性能。
  • 测试与测量:测量阻值时建议在电路断电条件下进行,必要时采用四线法提高测量精度;注意测量电流热效应对小阻值元件的影响(本件阻值较大,影响较小)。
  • 环境适配:工作温度范围宽(-55 ℃ 至 +155 ℃),适合多数工业与民用环境,但在极端腐蚀或化学气氛中应关注表面钝化与封装保护需求。

六、包装、存储与可靠性

  • 包装方式通常为卷带(reel)以适配自动贴装机;使用前建议按生产批次核对外观与阻值。
  • 存储条件建议干燥、常温并避免阳光直射,长期存放应防潮并遵循厂商建议的存储期限。
  • 可靠性:厚膜电阻在常规电子产品应用中表现稳定,能满足一般的温度循环、机械振动与印制电路板装配要求。对关键或高可靠性场合,建议参照厂商的详细可靠性试验报告与认证指标进行评估。

总结:0402WGJ0473TCE 是一款面向高密度 PCB 设计的通用型厚膜贴片电阻,47kΩ/±5% 的阻值组合适合多种信号与偏置电路。选型时应重点考虑功率余量与热管理,合理的设计与焊接工艺可确保其在目标应用中的长期可靠性。若需更详细的回流曲线、可靠性测试数据或供货信息,建议联系 UNI-ROYAL(厚声)或授权经销商获取产品技术资料。

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.
