0201WMF2802TEE 贴片厚膜电阻产品概述

一、产品核心身份与定位

0201WMF2802TEE是UNI-ROYAL(厚声) 推出的一款0201封装厚膜贴片电阻,属于中小功率精密电阻范畴。型号各部分含义明确:

  • “0201”对应英制封装尺寸(0.02in×0.01in,公制0.5mm×0.25mm);
  • “WMF”为厚声厚膜电阻系列标识;
  • “2802”代表阻值28kΩ(前三位“280”为有效数字,第四位“2”表示×10²);
  • “TEE”关联精度、温度系数等性能参数定义。

该产品针对高密度PCB设计需求,兼顾精度、功率与成本,适用于多类电子设备的信号调理、偏置电路等场景。

二、关键性能参数深度解析

核心参数围绕“精准稳定、小功率适配”设计,具体如下:

  1. 阻值与精度:标称阻值28kΩ,精度±1%——满足一般精密电路对阻值偏差的要求,无需额外校准即可用于信号放大、滤波等需稳定阻抗的场景;
  2. 功率与电压:额定功率50mW,最大工作电压25V——实际工作需同时满足两项约束(经计算:25V下功耗≈22.3mW,远低于额定功率,余量充足);
  3. 温度系数:±200ppm/℃——温度每变化1℃,阻值变化±0.02%;极端温度(-55℃~+155℃)下最大偏差约±4%,覆盖多数场景温度波动;
  4. 宽温范围:-55℃~+155℃——适配户外、车载等温度变化大的环境,无需额外散热或补偿。

三、封装与工艺特性

  1. 0201超小封装:作为最小贴片电阻封装之一,尺寸仅0.5mm×0.25mm,可显著缩小PCB布局面积,适配智能手机、智能穿戴、小型通信模块等体积严苛的产品;
  2. 厚膜工艺优势:采用丝网印刷+高温烧结工艺,相比薄膜电阻成本更低,且厚膜层与陶瓷基板结合牢固,抗冲击、振动性能更优,适合批量生产与工业级应用;
  3. 贴装兼容性:符合SMD标准,支持常规回流焊、波峰焊工艺,适配自动化组装线,生产效率高。

四、典型应用场景

该电阻的参数特性使其覆盖多领域:

  1. 消费电子:智能手机音频调理(耳机放大器偏置)、智能穿戴传感器滤波;
  2. 工业控制:小型PLC信号放大、传感器输出调理(如温度/压力传感器);
  3. 汽车电子:车载显示屏背光控制、胎压监测传感器信号处理(需确认AEC-Q200认证,厚声部分产品可满足);
  4. 通信设备:5G小模块偏置电路、路由器射频匹配电阻;
  5. 医疗设备:家用血糖仪、血压计检测电路(精度与宽温满足可靠性要求)。

五、可靠性与品质保障

UNI-ROYAL厚声作为国内电阻制造龙头,该产品具备:

  1. 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,适配绿色设计;
  2. 一致性优异:批量生产中阻值、温度系数控制严格,适合大规模组装;
  3. 可靠性验证:经过高低温循环、振动、冲击测试,典型MTBF(平均无故障时间)可达数万小时,满足工业级寿命要求。

六、总结

0201WMF2802TEE是一款高性价比的0201封装厚膜精密电阻,平衡了小体积、精准度与可靠性,广泛适配消费、工业、汽车等领域的中小功率电路设计,是高密度PCB方案的优选元件之一。

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
