0201WMJ0242TEE 产品概述

一、产品简介

0201WMJ0242TEE 为 UNI-ROYAL(厚声)出品的一款贴片厚膜电阻,属超小型0201封装,阻值为 2.4 kΩ,公差 ±5%,额定功率 50 mW。该器件以小体积、高封装密度为优势,适合空间受限的便携与高密度电路板设计。工作温度范围宽 (-55℃ 至 +155℃),适用于严苛环境下的基本限功耗应用。

二、主要技术参数

  • 阻值:2.4 kΩ
  • 精度:±5% (J级)
  • 额定功率:50 mW(室温,PCB散热条件下)
  • 额定工作电压:标称 25 V(产品规格表项)
  • 温度系数(TCR):±200 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0201(公称尺寸约 0.6 mm × 0.3 mm,具体以厂方数据为准)
  • 品牌:UNI-ROYAL(厚声)

三、电气特性说明与注意事项

  • 电压与功率限制:虽然规格列出“工作电压 25 V”,但在实际应用中需以功率极限来限制跨压。由 P = V^2 / R,可计算连续工作时允许的最大电压约为 Vmax = sqrt(P·R) ≈ sqrt(0.05×2400) ≈ 10.95 V。因此长时间施加超过 ~11 V 的电压会导致过载发热,可能烧毁元件。建议按较严格的限制选择使用电压。
  • 温漂影响:TCR 为 ±200 ppm/℃,以 25℃ 为基准,温度升高 70℃ 时,阻值变化约为 0.014(即 1.4%),相当于约 33.6 Ω 的偏移,需在精密电路中考虑温度漂移带来的误差累积。
  • 功率热沉:0201 封装自身热容与散热能力有限,实际可承受功率与 PCB 板材、铜箔面积和环境温度相关,推荐留有合理的铜箔散热区并遵循功率降额曲线。

四、典型应用场景

  • 移动终端、穿戴设备、IoT 芯片外围的阻值网络(拉/下拉、电压分压)
  • 高频/高密度 PCB 上的常规限流、偏置与信号阻抗匹配(非高精度场合)
  • 消费类电子产品中对体积要求极高且功率需求低的电路设计

五、封装与装配建议

  • 0201 为超小封装,贴装时建议使用细间距取放设备与精密贴片机,避免机械应力与过大焊膏量导致桥连或漂移。
  • 推荐按厂方回流焊温度曲线进行焊接,控制峰值温度及时间以免影响内部厚膜层。
  • 清洗与助焊剂残留需注意,避免长期侵蚀焊盘或导致电阻漂移。包装形式常见为卷带(Tape & Reel),便于贴片机使用。

六、可靠性与温度行为

  • 宽温范围(-55℃~+155℃)使其能在工业级环境中工作,但长期高温下需进行功率降额。
  • 在振动、热循环和机械冲击等可靠性设计中,0201 因体积小、焊接点相对脆弱,应在 PCB 设计和工艺控制上给予额外注意,以降低开路风险。

七、小结

0201WMJ0242TEE 是一款适合超高密度布线、低功率需求场合的厚膜贴片电阻,具有小体积、宽温区与常规精度的优势。设计使用时需重点关注功率与电压的匹配(实际连续电压以约 11 V 为安全上限)、温漂影响以及装配工艺控制。选型时若需更高精度或更大功率,请考虑替代封装或更高规格的电阻产品。若需详细机械图或回流焊曲线,请向 UNI-ROYAL 厂方索取完整规格书。

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
