0201WMJ0202TEE 厚膜贴片电阻产品概述

一、产品基本属性

0201WMJ0202TEE是厚声电子(UNI-ROYAL) 推出的通用型厚膜贴片电阻,型号命名对应核心参数:

  • "0201":英制封装尺寸(0.02英寸×0.01英寸,公制0.6mm×0.3mm);
  • "202":阻值代码(前两位有效数20+第三位10²次方,即20×10²=2000Ω=2kΩ);
  • "TEE":工艺与精度标识(厚膜烧结工艺、±5%精度)。

该产品定位为小功率高密度贴装电阻,适配消费电子、可穿戴设备等小型化场景,是主流通用电路的常用元件。

二、核心性能参数详解

关键参数满足多数通用电路需求,具体如下:

  1. 阻值与精度:标称阻值2kΩ,精度±5%(通用级,适用于对误差要求不苛刻的电路,如分压、限流);
  2. 功率特性:额定功率50mW(0.05W),实际使用需降额(推荐≤35mW,延长寿命);
  3. 电压限制:最大工作电压25V(需同时满足功率约束,实际最大安全电压为√(P×R)=10V);
  4. 温度系数(TC):±200ppm/℃,即温度每变化1℃,阻值变化±0.4Ω,稳定性覆盖工业级环境;
  5. 工作温度范围:-55℃~+155℃,支持低温存储、高温工作(如车载辅助电路、工业传感器)。

三、封装与工艺特性

3.1 封装尺寸

0201是目前最小的贴片电阻封装之一,公制尺寸为0.6mm(长)×0.3mm(宽)×0.23mm(厚),体积仅为0402封装的1/4,可大幅提升PCB贴装密度,适配智能手环、蓝牙耳机等小型设备。

3.2 厚膜工艺优势

采用氧化铝陶瓷基底+钌系氧化物厚膜层+环氧树脂保护层的结构:

  • 陶瓷基底耐高温(155℃长期稳定)、机械强度可靠;
  • 厚膜层烧结附着力强,长期漂移≤0.3%(125℃/1000h);
  • 保护层抗潮湿、防划伤,提升环境适应性。

四、典型应用场景

因小体积、低功耗、宽温特性,广泛应用于:

  1. 消费电子:智能手机/平板的音频滤波电路(如耳机接口限流)、电源管理模块(低功耗DC-DC反馈电阻);
  2. 可穿戴设备:智能手环的心率传感器分压电阻、蓝牙模块的射频匹配电阻;
  3. 工业控制:小型PLC的IO接口限流电阻、温度传感器的上拉电阻;
  4. 汽车电子(辅助场景):车载USB过流保护电阻、胎压监测辅助电路;
  5. 通信设备:小型基站的射频前端辅助电阻、光纤收发器的低功耗控制电阻。

五、可靠性与环境适应性

通过多项工业级测试,性能稳定:

  1. 温度循环:-55℃(30min)→+155℃(30min)循环100次,阻值变化≤±0.5%;
  2. 湿度测试:85℃/85%RH存储1000h,阻值变化≤±1%;
  3. 焊接可靠性:适配回流焊(峰值240250℃,时间3060s),无虚焊、脱落;
  4. 机械应力:承受1000次25mm曲率弯曲,阻值变化≤±0.2%;
  5. 长期稳定性:125℃存储1000h,漂移≤±0.3%,满足设备长期工作需求。

六、选型与使用注意事项

  1. 功率降额:实际功率需≤35mW(70%额定值),避免高温老化;
  2. 电压匹配:需同时满足V≤25V和P≤I²R,实际安全电压为10V(需根据电路电流计算);
  3. 贴装工艺:需高精度贴片机(贴装精度≤±0.05mm),避免偏移导致焊接不良;
  4. 存储条件:常温干燥环境(25±5℃,湿度≤60%),开封后1个月内使用,防止吸潮;
  5. 替代选型:若需±1%精度,换同封装金属膜电阻;若需更大功率(62.5mW),换0402封装型号。

该产品以高性价比、稳定性能成为通用电路的优选元件,适配多领域小型化设计需求。

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
