0201WMJ0621TEE 产品概述

一、产品简介

0201WMJ0621TEE 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,阻值为 620Ω,精度 ±5%,额定功率 50mW,额定工作电压 25V。该器件采用超小型 0201 封装,适用于对体积、重量要求严格的高密度表面贴装电路板(SMT)。工作温度范围宽,-55℃ 到 +155℃,能满足工业级及消费类电子产品的常见温度环境需求。

二、主要技术参数

  • 电阻类型:厚膜电阻
  • 阻值:620Ω
  • 精度:±5%(E24)
  • 额定功率:50mW
  • 额定工作电压:25V
  • 温度系数(TCR):±200ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0201(超小型表面贴装)
  • 品牌:UNI-ROYAL(厚声)

三、特点与优势

  • 超小体积:0201 封装适配高密度贴片工艺,节省 PCB 面积,便于智能手机、可穿戴设备等微型化产品设计。
  • 良好的一致性与可制造性:厚膜工艺成熟,焊接与焊后可靠性稳定,适合大批量自动化贴装生产。
  • 宽温区适应性:-55℃ 至 +155℃ 的工作温度范围,适合复杂环境和工业级应用。
  • 成本效益高:相较于薄膜电阻,厚膜电阻在中高阻值和常规精度条件下具备更佳的成本优势。
  • 通用电性能:50mW 功耗与 25V 工作电压适合多数低功耗信号链和分压、限流等场合。

四、典型应用场景

  • 移动设备与可穿戴电子(有限 PCB 面积的电源分压、信号匹配)
  • 消费电子(遥控器、耳机、便携式设备)
  • 工业控制和传感器前端(信号调理、分流保护)
  • 通信设备(滤波、偏置电路)
  • 其他要求高密度贴装与低功耗的电子模块

五、封装与外观

0201 封装为超小型矩形贴片,适配常规 SMT 贴片机及回流焊工艺。外观通常为两端电极、中心主体为厚膜电阻膜层,表面覆保护釉,满足常规目视检查与自动光学检测(AOI)要求。具体尺寸请参照厂商尺寸图与 PCB 封装库。

六、使用与焊接建议

  • 推荐采用标准回流焊工艺,遵循 J-STD-020 热循环规范,峰值温度通常不超过 260℃。
  • 通过合理的 PCB 板面铜箔设计与热隔离,避免局部过热导致功耗集中;小封装器件散热能力有限,使用时需考虑功率降额。
  • 尽量减少在器件端施加机械应力,避免在波峰焊或手工焊接过程中对芯片施加过大压力。
  • 对于高可靠性场合,建议进行焊后清洁并避免残留腐蚀性溶剂。

七、储存与可靠性

  • 常温干燥环境下密封保存,避免潮湿、强腐蚀性气体与剧烈振动。
  • 建议在原包装内、静电保护措施到位的条件下保存,长期储存前可参考厂商的保质期建议。
  • 厚膜电阻在常规工作条件下具有良好的寿命与稳定性,但在超额定功率或超温环境下需注意性能漂移与失效风险。

八、订购信息与注意事项

  • 型号:0201WMJ0621TEE(UNI-ROYAL)
  • 选型时请确认阻值与公差是否满足电路容限,若需更高精度或更低 TCR,请咨询替代型号或薄膜系列。
  • 常规出货形式为盘带(适配自动贴片机器),大批量采购可洽谈交期与质保。
  • 如需详细的尺寸图、回流曲线、可靠性测试报告(如湿热、温度循环、机械冲击等),请向供应商索取数据手册与样品进行评估。

如需将该型号纳入设计库(封装库、3D 模型)或需要更详细的电气与热特性曲线,我可协助整理并提供设计建议。

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
