0402WGF9101TCE 产品概述

一、产品简介

0402WGF9101TCE 是 UNI-ROYAL(厚声)品牌的一款厚膜贴片电阻,封装为 0402(约 1.0 mm × 0.5 mm),阻值 9.1 kΩ,精度 ±1%,额定功率 62.5 mW(常称 1/16W),工作电压额定 50 V,温度系数(TCR)±100 ppm/°C,工作温度范围 -55°C 至 +155°C。此型号面向对尺寸与成本敏感的低功耗与信号回路,兼顾常规商业与工业类应用。

二、主要技术参数

  • 电阻类型:厚膜电阻(Thick film)
  • 阻值:9.1 kΩ
  • 精度:±1%
  • 额定功率:62.5 mW(典型额定在 70°C 环境)
  • 最大工作电压:50 V(器件额定极限)
  • 温度系数:±100 ppm/°C
  • 工作温度范围:-55°C ~ +155°C
  • 封装:0402(约 1.0 × 0.5 mm)
  • 品牌:UNI-ROYAL(厚声)
  • 包装:支持卷带(Tape & Reel),适合自动贴片生产

三、性能特点与设计要点

  • 小尺寸:0402 尺寸可显著节省 PCB 面积,适合高密度 SMT 设计。
  • 成本效益高:厚膜工艺在中等精度(±1%)和常规稳定性下成本较低,适合大批量通用电路。
  • 温漂适中:±100 ppm/°C 的 TCR 对于一般模拟与数字电路足够;举例说明,若环境温度变化 50°C,电阻值大约变化 0.5%(100 ppm/°C × 50°C = 5000 ppm = 0.5%)。
  • 功率与电压注意事项:额定功率 62.5 mW 意味着在阻值 9.1 kΩ 条件下,基于功率限制的最大安全直流电压约为 sqrt(P·R) ≈ 23.8 V;器件标称最大工作电压 50 V 为电压绝对限制,但在任何情况下都不得使器件功耗超过 62.5 mW,否则会导致过热或失效。

四、典型应用场景

  • 低功耗信号通路:分压器、上拉/下拉电阻、偏置网络
  • 便携与消费电子:传感器接口、MCU 外围电路
  • 工业与仪器:不是高精密测量但需要小体积的电阻应用
  • 通信与物联网终端:空间受限的阻值网络

五、封装与贴装建议

  • 0402 尺寸对焊接与贴装精度要求较高,建议使用精确的 PCB land pattern(焊盘)和适当的阻焊间隙以利于焊膏印刷与回流焊过程。
  • 与回流焊兼容:适用于常见的无铅回流工艺(请依据供应商具体回流曲线控制峰值温度与时间)。
  • 机械应力避免:0402 尺寸对 PCB 弯曲与波峰/手工焊接应力敏感,设计时应保证器件附近与板边、固定孔等可能产生应力的位置有足够间距。
  • 自动贴装:建议采用卷带包装并配合适当的取放参数,以保证贴装良率。

六、可靠性与环境适应

  • 工作温度 -55°C 至 +155°C,适用于大多数工业级温度要求;高温下应按厂商给出的功率降额曲线进行设计。
  • 常见的可靠性试验(如焊接可靠性、温湿循环、恒定电流老化)通常适用于厚膜电阻的质量评估,应用前建议做针对具体应用的验证测试。
  • 储存与处理:避免在高湿、高温、受污染环境长期储存;贴装前应避免直接接触阻焊剂或强腐蚀性清洗剂。

七、选型与采购建议

  • 若系统对温漂或噪声有更严格要求,可考虑薄膜或金属膜/金属氧化物类高精度电阻;若注重成本与常规性能,0402WGF9101TCE 是合理选择。
  • 批量采购时确认卷带包装规格(卷轴长度、每盘数量)与可追溯的批次信息,以利 SMT 生产连续性。
  • 对关键应用建议向供应商索取完整的规格书、环境与可靠性测试报告,以及典型的回流焊工艺参数。

八、注意事项

  • 切勿只按最大工作电压判断安全性,必须同时满足功率限制(例如在本型号上持续施加 50 V 会使器件功耗远超额定值,从而损坏器件)。
  • 在高频或高精度测量场合,厚膜电阻的噪声与热稳性应提前评估。
  • 设计时考虑功率降额(derating)和散热条件,避免长期在峰值条件下工作以延长可靠性寿命。

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.
