0201WMJ022JTEE 产品概述

一、产品简介

0201WMJ022JTEE 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,阻值 2.2Ω,公差 ±5%,额定功率 1/20W(50mW),封装规格 0201。该器件适用于对占板面积和高度要求极低的高密度印制电路板(PCB),为微功率低阻值应用提供稳定的阻性元件。

二、主要参数

  • 电阻类型:厚膜电阻
  • 阻值:2.2Ω
  • 精度:±5% (J)
  • 额定功率:50mW(1/20W)
  • 最高工作电压:25V
  • 温度系数(TCR):±400 ppm/°C
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0201(超小型贴片封装)

三、性能特点

  • 极小体积:0201 封装适合超高密度布局,能有效节省 PCB 空间。
  • 小功率损耗:50mW 额定功率适配低能耗电路,适合信号级与微功率回路。
  • 宽温度范围:-55℃ 到 +155℃ 的工作温度满足工业级温度耐受需求。
  • 温漂适中:±400 ppm/°C 的温度系数在厚膜低阻产品中属常见水平,适用于对精密温漂要求不高的场合。
  • 兼容表面贴装:设计用于常规贴装和回流焊工艺(请参考具体回流曲线与焊接工艺规范)。

四、典型应用

  • 移动设备与可穿戴设备中的去耦或分流元件
  • 低电流检测与电流限制(需注意功率及测量精度限制)
  • 高频通信终端的阻尼与匹配网络
  • IoT 传感与控制模块中的空间受限电路
  • 各类消费电子与微型化控制板上作为通用阻性元件

五、装配与注意事项

  • 由于 0201 封装尺寸极小,建议使用高精度贴片机与合适的吸嘴以保证贴装精度。
  • 建议严格控制焊膏印刷量,避免锡膏过量导致立碑或焊接缺陷;遵循器件及工艺的回流温度曲线。
  • 使用测量与测试时需考虑接触电阻与测量夹具影响,推荐四端/开尔文测量方法以提高低阻测量准确性。
  • 避免超过 25V 的工作电压及长期在额定温度极限附近运行,以防功率降额或寿命缩短。

六、可靠性与环境适应

该系列电阻在常规的环境与振动应力下具有良好的可靠性表现,适配商业至工业温度等级。为延长使用寿命,应避免长期大功率消耗与过温工作。存储时应避免潮湿、强腐蚀性气体与剧烈机械冲击。

七、订购信息与替代建议

型号:0201WMJ022JTEE;品牌:UNI-ROYAL(厚声)。如需更高精度或更低温漂的方案,可考虑更高精度(1%)或金属膜/薄膜低阻方案;如需更大功率或耐脉冲能力,可选用更大封装或专用电流检测电阻。购买与样品获取请联系授权经销商或供应链渠道,并明确包装方式(卷带/带卷)与出货数量。

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
