0201WMJ0562TEE 产品概述

一、主要特性

0201WMJ0562TEE 是 UNI-ROYAL(厚声)推出的一款超小型贴片厚膜电阻,规格为 5.6kΩ ±5%,功率额定 50mW,最大工作电压 25V,温度系数(TCR)±200ppm/℃,工作温度范围 -55℃ 至 +155℃。封装为 0201(超小型 SMD),适合对占板面积和重量有严格限制的现代电子产品。

二、电气参数与实用计算

  • 阻值:5.6kΩ ±5%(初始精度为 ±5%)
  • 额定功率:50mW(请参考厂方温度降额曲线)
  • 最大工作电压:25V(器件击穿极限),但同时需满足功率限制
  • TCR:±200ppm/℃(温度变化影响阻值,非高精度类型) 实用计算:
  • 允许最大电流(由功率决定):Imax = sqrt(P/R) ≈ sqrt(0.05/5600) ≈ 3.0mA
  • 在功率限制下允许的最大两端电压:Vmax(P) = sqrt(P·R) ≈ 16.7V 注意:理论最大电压 25V 与由功率得出的约 16.7V 需同时满足,实际应用以更严格的一项为准,并考虑热降额与脉冲条件。

三、温度与阻值漂移

TCR ±200ppm/℃ 表明温度上升会引起阻值随之变化,例如从 25℃ 升高到 125℃(ΔT=100℃)时,阻值可能变化约 2%(200ppm×100℃ = 20000ppm = 2%)。与初始 ±5% 公差叠加,长期或高温运行下的阻值偏差需在电路设计中预留余量。

四、应用场景

  • 移动设备、可穿戴及微型传感终端中的分压、上拉/下拉与偏置电路
  • 低电流信号路径、模拟前端的阻网络(非高精度参考)
  • 板上空间受限且对功耗、热量敏感的消费电子产品 该器件适合低功率、低电流场合,不建议用于高电流或高精度阻值要求的场合。

五、封装与装配注意事项

0201 超小封装适合自动化贴装与回流焊工艺,但对贴装精度、焊膏印刷与回流曲线要求较高。器件尺寸较小,通常不做表面标记,采购与库房管理需用料号和条码识别。建议采用 tape‑and‑reel 包装以提高贴装效率;回流工艺请参照厂方推荐温度曲线,并注意清洗残留焊剂以避免长期可靠性问题。

六、可靠性与热管理建议

  • 工作环境温度与板上热源会影响额定功率,应参考厂方的温度降额曲线进行设计,必要时降低实际耗散功率或增大铜箔散热面积。
  • 由于额定功率仅 50mW,建议在连续功率应用中留有足够裕量,避免接近额定值长期运行。
  • 对冲击、振动及焊接应力具有一般工业级可靠性,适合宽温应用(-55℃~+155℃)。

七、选型与替代建议

若需更高精度或更低 TCR,可考虑金属膜或薄膜精密电阻;若需更大功率,应选择更大封装或专用功率电阻。0201WMJ0562TEE 适用于体积受限且为一般公差、一般稳定性需求的低功耗场合,是成本与体积优化的常用选型。

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
