0201WMF3093TEE 产品概述

一、产品简介

0201WMF3093TEE 是 UNI-ROYAL(厚声)系列的厚膜贴片电阻,阻值 309kΩ,精度 ±1%,额定功率 1/20W(50mW),工作电压 25V,温度系数(TCR)±200ppm/℃,工作温度范围 -55℃ 至 +155℃。该器件采用超小型 0201 封装,适配高密度贴片电路板与微型化电子产品的设计需求,兼顾体积、精度与可靠性。

二、主要性能与规格

  • 电阻类型:厚膜电阻
  • 标称阻值:309kΩ
  • 精度(容差):±1%
  • 额定功率:50mW(1/20W,基于标准环境条件)
  • 工作电压:25V(最大连续工作电压)
  • 温度系数(TCR):±200ppm/℃(代表每摄氏度电阻值的相对变化)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0201(超小贴片,尺寸约 0.6mm × 0.3mm,具体尺寸以厂家资料为准)
  • 品牌:UNI-ROYAL(厚声)

三、电气性能计算与使用建议

  • 电压与电流限制:器件标称工作电压为 25V,因此在该电压下最大连续电流约为 I = V / R = 25V / 309kΩ ≈ 80.9 μA。虽然按功率计算的电流上限(由 P = I^2·R 得到)约为 402 μA,但实际应用应以工作电压限值为准,超过 25V 将可能引起表面击穿或长时间失效。
  • 功率与散热:0201 封装的尺寸极小,热容量和散热能力有限。即使额定功率为 50mW,也建议对功率进行适当降额(derating),尤其在高环境温度或密集布线情况下,应参考制造商的热特性曲线并留有裕量。
  • 温漂(TCR)影响:±200ppm/℃ 等于 ±0.02%/℃。举例:若工作温度从 25℃ 上升 100℃(到 125℃),阻值的可能变化约为 100 × 0.02% = 2%。在对温漂敏感的精密电路中需考虑这一变化并通过匹配或温度补偿设计来处理。
  • 脉冲与冲击:对于脉冲功率或瞬态高压,需特别评估能否超过额定功率或工作电压;若存在短时大电流或高压脉冲,建议选择更大功率或更高工作电压等级的器件。

四、封装与焊接建议

  • 封装适配:0201 超小封装适用于高密度 PCB 设计,但对贴装设备精度、锡膏印刷及回流温度控制要求较高。
  • 焊接工艺:兼容常规回流焊(包含无铅工艺),建议使用制造商推荐的回流曲线以避免过热或冷却过快引起的应力。避免多次高温回流及超出规范的手工焊接。
  • 贴装注意事项:在贴装和回流过程中注意静电防护(ESD),并使用经校正的点胶/点印/贴片程序保证焊接一致性。0201 的微小足迹对锡膏量和印刷精度非常敏感,应优化焊盘设计及焊接流程。

五、典型应用场景

  • 移动终端、可穿戴设备等微型化电子产品中用于分压、偏置与阻抗匹配。
  • 物联网模块、传感器前端与低功率模拟电路,适合对体积有严格要求的设计。
  • 工业与消费类电子的高密度 PCB 中作为通用电阻件使用(在满足电压与功耗限制下)。

六、可靠性与存储

  • 环境耐受:工作温度范围宽(-55℃ 至 +155℃),适应工业级温度循环与长期使用,但在极端温度或高湿环境中仍应遵循厂家可靠性测试结果。
  • 存储与搬运:保持干燥、避光、防潮、防静电。长期储存前建议放置在密封干燥包装中,开卷后尽快使用以防潮湿影响焊接性。
  • 质保与测试:建议在量产前对样品进行焊接、温度循环与电气测试以确认在目标应用工况下的稳定性。

七、选型与采购建议

0201WMF3093TEE 以其超小封装与 ±1% 的较高精度适合空间受限、对精度有一定要求的低功耗电路。选型时需确认最大工作电压、环境温度和允许的功率裕度以避免失效;在批量采购前建议索取器件的完整数据手册(datasheet)和可靠性报告,并与供应商确认包装形式(卷带规格)、交期与质量保证条款。

总结:0201WMF3093TEE 提供小体积与良好精度的平衡,适用于高密度、低功耗的应用场景。正确的热管理、回流焊控制与电气限值遵守是保障长期稳定性的关键。若需更详细的热特性、包装尺寸或回流曲线,请联系供应商索取原厂资料。

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.
