0201WMF1132TEE 产品概述

一、产品简介

0201WMF1132TEE 是 UNI-ROYAL(厚声)系列的厚膜贴片电阻,阻值为 11.3 kΩ,精度 ±1%,额定功率 1/20W(50 mW),适用于超小型、高密度印制电路板的表面贴装应用。该器件采用 0201 封装,体积极小,适合对空间和重量有严格限制的消费电子、移动设备、传感器模块及精密电子测量电路等场景。

二、主要技术参数

  • 电阻类型:厚膜电阻
  • 阻值:11.3 kΩ
  • 精度:±1%(B级)
  • 额定功率:50 mW(1/20W)
  • 工作电压:25 V
  • 温度系数(TCR):±200 ppm/°C
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0201(极小型贴片)
  • 品牌:UNI-ROYAL(厚声)
  • 标称型号:0201WMF1132TEE

三、产品特点

  • 体积小、适配高密度布局:0201 封装可显著节省 PCB 面积,便于移动设备与微型化模组设计。
  • 精度稳定:±1% 精度满足多数模拟和数字电路对阻值精度的要求。
  • 宽温度范围:-55 ℃ 至 +155 ℃,可适应工业级及更广泛的环境条件。
  • 合理的温漂性能:±200 ppm/°C 的温度系数适合一般温度敏感度中等的应用。
  • 低功耗设计:50 mW 的额定功率适合信号链、偏置网络及低功率电路。

四、典型应用场景

  • 移动终端与可穿戴设备:用于分压、偏置、滤波等需要节省 PCB 面积的电路。
  • 传感器与测量模块:在信号调理、参考电阻和输入匹配中应用。
  • 无线通信终端:用于射频模块的直流偏置与匹配(注意功率及频率相关的布局要求)。
  • 低功耗电子产品:适用于对功耗和空间均有严格控制的电路设计。

五、封装与装配建议

  • 焊接工艺:兼容常规的无铅回流焊工艺,建议按参考回流曲线进行工艺验证以避免过热引起的性能漂移或焊接缺陷。
  • PCB 布局:由于体积极小,焊盘设计需严格遵循供应商推荐尺寸,避免过大或过小的焊盘导致焊接不良。焊盘过大可能导致偏位或焊接裂纹;过小则可能影响焊点可靠性。
  • 热管理与功率裕量:0201 的散热能力有限,建议在设计时留有裕量,尽量将实际工作功耗控制在额定功率的 70% 以下,或根据实际环境温度适当降额使用,以提高长期可靠性。
  • 安装注意:器件尺寸微小,拾放与贴装需采用高精度贴片机;在手工焊接或返修时需使用显微设备并控制热量与时间,避免机械应力与过热。

六、可靠性与环境适应

  • 温度循环与机械疲劳:小体积器件对机械应力较敏感,建议在振动或冲击较强的场合做可靠性验证。
  • 温漂与长期稳定性:±200 ppm/℃ 的温度系数在多数工业与消费场景可接受;在高精度测量应⽤中需要考虑温度补偿或选用更低 TCR 的元件。
  • 贮存与防护:建议在干燥、无尘环境中存放,遵循元器件湿敏等级(MSL)要求,避免长时间潮湿暴露,贴片卷带开封后应按厂家建议尽快使用或回烘以防加湿影响返修。

七、选型与替代建议

  • 若电路对温漂、长期稳定性要求更高,可考虑金属膜或精密薄膜电阻替代。
  • 若需要更高功率能力或更高工作电压,应选择更大封装或更高额定功率的型号。
  • 在高频应用中,需综合考虑电阻自带的寄生电感、电容特性,必要时做仿真与测试验证。

八、购买与型号说明

型号 0201WMF1132TEE 中,“1132” 对应阻值编码(11.3 kΩ),0201 表示封装规格,“WMF” 表示厚膜贴片系列。选购时请确认包装形式(卷带)、湿敏等级及批次一致性,以便保证装配与可靠性。若有更严格的认证或特殊需求,请咨询 UNI-ROYAL(厚声)或经销商以获取详细数据手册与样品测试支持。

如需我提供该型号的 PCB 焊盘推荐尺寸、回流焊建议曲线或在特定应用(如传感器前端、阻抗匹配网络)中的使用示例,请告知具体电路与环境条件,我会给出针对性建议。

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
