0402WGF5232TCE 产品概述

一、产品简介

0402WGF5232TCE 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,阻值 52.3 kΩ,精度 ±1%,额定功率 62.5 mW,工作电压上限 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃~+155℃。封装为国际标准 0402(公制约 1005),适用于空间受限的高密度贴片电路板。

二、主要参数(摘要)

  • 电阻类型:厚膜贴片电阻
  • 阻值:52.3 kΩ
  • 精度等级:±1%(J)
  • 额定功率:62.5 mW(室温条件下)
  • 最大工作电压:50 V
  • 温度系数:±100 ppm/℃
  • 工作温度:-55℃ ~ +155℃
  • 封装:0402(1005)
  • 品牌:UNI-ROYAL(厚声)

三、产品特点与优势

  • 小型化封装(0402)适合高密度、轻薄型设备设计,节省 PCB 面积。
  • ±1% 精度可满足多数模拟电路与分压、偏置网络的精确度要求。
  • ±100 ppm/℃ 的 TCR 表现,在温度变化下具有稳定的阻值漂移控制,适用于一般精度的信号与测量电路。
  • 厚膜工艺成本效益高,耐焊性和量产一致性良好,适合批量贴装生产。
  • 额定功率与工作电压配合合理,适用于低功耗信号路径与偏置网络。

四、典型应用场景

  • 移动终端、可穿戴设备等空间受限的消费电子产品。
  • 模拟前端电路中的分压器、偏置电阻、反馈网络。
  • 传感器接口、微控制器 I/O 的上拉/下拉电阻。
  • 通信设备与仪器中需小体积、稳定电阻的场合。

五、PCB 设计与焊接建议

  • 封装对称焊盘设计有助于降低“立碑效应”(tombstoning),建议采用厂商或IPC推荐的 0402 焊盘布局。
  • 尽量保持焊盘尺寸和焊膏量的一致,减少铜箔散热差异,避免因局部过热导致阻值漂移或可靠性问题。
  • 对于长期连续功耗,建议遵循功率余量原则(留有安全余量),并参照厂商功率-温度降额曲线进行热设计;避免长期在额定功率附近工作。
  • 推荐采用标准回流焊工艺,遵守元器件最高温度和时间限制以保证可靠性。

六、选型与使用注意事项

  • 若电路对温漂要求更高(例如精密测量或高精密分压),可考虑更低 TCR(ppm/℃)或金属膜/薄膜电阻替代。
  • 电压降不得超过 50 V,实际使用建议留有裕量以提高可靠性。
  • 厚膜电阻在低频噪声与长期稳定性上通常优于廉价表面处理,但不及高端薄膜器件,选型时需权衡成本与性能。
  • 避免在机械应力集中的区域直接焊接或进行过度弯曲,以免损伤电阻体或引脚焊点。

七、包装与订购信息

  • 常见为卷盘(Tape & Reel)包装,便于自动贴片机(SMT)生产线使用;具体包装规格请参考厂商出货单或与供应商确认。
  • 订购时请以完整型号 0402WGF5232TCE 或咨询UNI-ROYAL 授权经销商以获取最新的库存与质量保障信息。

如需更详细的电气特性曲线(如功率-温度降额曲线、寿命试验数据、焊接耐受曲线)或 PCB 封装推荐,请提供用途说明或索取厂商完整数据表以便进一步优化设计。

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
