0201WMF1272TEE 产品概述

一、产品简介

0201WMF1272TEE 是 UNI-ROYAL(厚声)推出的一款厚膜贴片电阻,阻值为 12.7 kΩ,精度 ±1%,额定功率 50 mW,额定工作电压 25 V,温度系数(TCR)为 ±200 ppm/℃,工作温度范围为 -55℃ 至 +155℃,封装为极小型 0201。该器件专为高密度电路板与精密模拟应用设计,兼顾体积最小化与稳定的电气性能。

二、主要特点

  • 精确阻值与高精度:12.7 kΩ ±1% 满足多数精密分压、偏置与滤波网络的需求。
  • 小型化封装:0201 封装(典型尺寸约 0.6 mm × 0.3 mm),有利于高密度布局与微型化产品设计。
  • 电热性能可靠:额定功率 50 mW,额定工作电压 25 V,满足低功耗信号链与便携设备应用。
  • 宽温工作范围:-55℃~+155℃,适应工业级环境温度要求。
  • 工艺与兼容性:厚膜工艺具有良好的批量一致性与成本优势,适配常规无铅回流焊工艺。

三、电气与热学说明

  • 功率与电压:额定功率 50 mW,对应的理论最大允许电压可由 V = sqrt(P·R) 计算,约为 25.2 V,与本型号标称工作电压 25 V 相匹配。实际使用时建议留有裕量,避免长期在极限值下工作。
  • 温度系数:±200 ppm/℃,说明温度每变化 100℃ 时阻值变化大约 2%,在精密测量或温度敏感电路中应考虑温度漂移影响。
  • 温度降额:随环境温度升高,器件可承受的功率需线性降额,请在热设计时参考供应商的功率降额曲线并适当增加散热铜箔面积以改善热耗散。

四、应用场景

  • 高密度消费电子(智能手表、可穿戴设备、手机模组)中的偏置与分压电路。
  • 精密模拟前端、ADC 输入匹配与滤波网络(在允许的热漂与噪声水平内)。
  • 物联网终端、便携式仪器中要求小体积与稳定阻值的场合。
  • 高密度电源管理与数模混合电路的阻值配置(非大电流取样)。

五、封装与装配建议

  • 0201 为超小型封装,焊接与贴装需使用精密贴片设备与合适的回流曲线。该器件适用无铅回流工艺,但具体回流温度曲线请参照制造商建议。
  • 由于 0201 体积小,焊盘与 PCB 铜箔面积会直接影响热耗散与功率能力。需要时可在 PCB 设计中适当扩大焊盘或增加背面铜层以改善热传导。
  • 0201 尺寸过小,器件本身无可见标识,推荐在物料管理与贴装程序中采用严格的料带管理与追溯措施。

六、可靠性与注意事项

  • 本型号适用宽温工业环境,但若用于汽车级或极端冲击/振动环境,请向供应商确认是否通过 AEC-Q200 或其它相关认证。
  • 长期在最高额定电压或高环境温度下工作会加速漂移,应在设计中预留裕度以保证长期稳定性。
  • 对于低噪声或低温漂应用,如需更优的 TCR 或更高稳定性,建议选用金属膜或薄膜电阻系列产品。

七、选型与采购建议

在选型时,确认实际电路中的最大交流/脉冲电压幅值、环境温度范围与长期可靠性要求。0201WMF1272TEE 适合需要极致体积控制且电压、功率处于器件额定范围内的设计。若需样品或批量采购,请注明型号 0201WMF1272TEE、阻值 12.7 kΩ、精度 1%,并向 UNI-ROYAL 指定分销渠道索取完整数据手册与功率降额曲线,以便进行最终的热与可靠性验证。

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
