0201WMF4122TEE厚膜贴片电阻产品概述

一、产品基本属性

0201WMF4122TEE是UNI-ROYAL(厚声) 推出的一款厚膜贴片电阻,属于小型化通用型电子元器件。该型号以0201封装为核心设计,针对高密度PCB布局场景优化,兼具性能稳定性与封装紧凑性,是消费电子、工业控制等领域的常规电阻选择。

二、关键性能参数解析

该电阻的核心参数经过标准化设计,适配多数应用场景需求,具体如下:

  • 阻值与精度:41.2kΩ(三位数字代码“4122”,即412×10²Ω),精度±1%,满足信号调理、分压电路等对阻值一致性的常规要求;
  • 功率等级:50mW(0.05W),为0201封装电阻的典型功率规格,适配低功耗电路;
  • 工作电压:25V(额定电压),实际功耗需满足 ( P=V^2/R \leq 50mW )(如25V下最大允许电流约0.6mA);
  • 温度系数(TCR):±200ppm/℃,表示每变化1℃阻值漂移±0.02%。以工作温度范围(-55℃~+155℃)为例,最大阻值变化约±4.2%,可适应宽温环境;
  • 工作温度范围:-55℃~+155℃,覆盖工业级与汽车级基础环境要求,极端温度下性能稳定。

三、封装与物理特性

该电阻采用0201封装(英制尺寸:0.02英寸×0.01英寸),公制尺寸为:

  • 长度:0.508mm±0.05mm;
  • 宽度:0.254mm±0.05mm;
  • 厚度:0.203mm±0.03mm;

封装结构基于氧化铝陶瓷基片,表面印刷钌系氧化物厚膜电阻浆料,端电极采用镍-铜-锡三层镀层,既保证焊接兼容性(适配回流焊、波峰焊),又提升了焊接附着力与抗腐蚀性。

四、典型应用场景

0201WMF4122TEE的小型化、宽温特性使其适用于以下场景:

  1. 消费电子与可穿戴设备:智能手机、蓝牙耳机、智能手环的传感器信号调理电路(分压、限流),0201封装可节省PCB空间;
  2. 工业控制模块:小型PLC、传感器节点的低功耗电路,宽温范围适应车间温度波动;
  3. 汽车电子辅助电路:车载显示屏背光控制、传感器信号处理模块,满足-40℃~+85℃的汽车级基础要求;
  4. 通信设备:小型路由器、无线模块的电源滤波、信号匹配电路,适配高密度布局需求。

五、品牌与可靠性保障

UNI-ROYAL(厚声)作为国内知名被动元器件厂商,该产品通过多项可靠性测试:

  • 符合RoHS 2.0、REACH环保标准,无铅焊接兼容;
  • 高温老化(155℃×1000小时)后阻值变化≤±0.5%;
  • 湿度测试(85℃/85%RH×1000小时)性能稳定;
  • 焊接可靠性符合IPC-J-STD-002标准,端电极附着力强,无脱落风险。

六、选型与使用注意事项

  1. 选型匹配:确认电路功率≤50mW,精度需求匹配(精密电路需更高精度则不适用);
  2. 焊接规范:回流焊峰值温度≤245℃(时间≤10秒),波峰焊温度≤260℃(时间≤5秒),避免过热损坏;
  3. 存储与使用:存储环境干燥(湿度≤60%)、常温(15℃~35℃),避免机械应力(如弯折PCB)导致开裂;
  4. 功率限制:严格控制实际功耗≤50mW,避免过载导致阻值漂移或损坏。

该产品以高性价比、稳定性能适配多领域小型化电路需求,是常规电阻选型的可靠选择。

Sourcing availability signal

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
