0201WMF4704TEE 厚膜贴片电阻产品概述

一、产品核心身份与基础属性

0201WMF4704TEE是UNI-ROYAL(厚声) 推出的一款厚膜贴片电阻,型号命名对应明确参数:

  • 「0201」:英制封装尺寸(0.02英寸×0.01英寸,公制0.6mm×0.3mm),为目前最小规格贴片电阻之一;
  • 「WMF」:厚声厚膜电阻系列标识,代表厚膜印刷+烧结工艺;
  • 「4704」:阻值编码(470×10⁴Ω=4.7MΩ);
  • 「TEE」:精度(±1%)、温度系数(±200ppm/℃)的参数组合编码。

该产品定位为小体积高精度通用电阻,适配高密度贴装与宽温环境下的信号电路。

二、关键电气性能参数解析

2.1 阻值与精度

阻值标称4.7MΩ,精度±1%——实际阻值范围为4.653MΩ~4.747MΩ,无需额外校准即可满足工业、消费电子对信号电路的精度要求(如传感器接口、运算放大器偏置)。

2.2 功率与电压匹配

  • 额定功率50mW:环境温度25℃、无强制散热时的连续工作功耗上限;若环境温度升高需降额(参考厚声官方曲线:100℃时降额至25mW,155℃时降额至12mW),避免电阻过热失效。
  • 工作电压25V:电阻两端可承受的最大直流/交流电压;需注意功率-电压匹配(P=U²/R):4.7MΩ电阻在25V时功耗约52mW,接近额定值,实际应用需预留10%~20%余量(如控制电压≤23V)。

2.3 温度系数与稳定性

温度系数**±200ppm/℃**——每变化1℃,阻值相对变化百万分之200。以工作温度范围(-55℃~+155℃)计算,温度变化最大210℃,阻值最大波动为±4.2%(结合±1%精度,总波动范围约±5.2%),可满足工业级设备对宽温稳定性的基本需求。

三、环境适应性与可靠性

3.1 宽温工作范围

-55℃~+155℃覆盖了:

  • 工业现场(-40℃~+85℃);
  • 部分便携设备高温场景(如户外智能终端);
  • 小型医疗设备(血糖仪、血氧仪的电池供电模块)。

无需额外散热或温度补偿,可长期稳定工作。

3.2 封装与抗干扰性

0201封装体积极小(约0.6mm×0.3mm×0.23mm),适配手机、智能手环等高密度PCB设计;厚膜工艺使电阻具有较好的抗脉冲能力(比薄膜电阻高2~3倍),可承受短暂过压/过流冲击(如电路瞬态尖峰),降低失效风险。

3.3 长期可靠性

厚声采用成熟的厚膜印刷+烧结工艺,电阻膜层均匀性好:

  • 1000小时高温负载(155℃+额定功率)下,阻值漂移≤0.5%;
  • 批量一致性达±0.5%(阻值公差、温度系数统计),减少电路调试成本。

四、典型应用场景

  1. 信号调理电路:运算放大器偏置电阻、传感器信号分压网络(如压力传感器、温度传感器接口),高阻值减少信号路径干扰;
  2. 便携电子设备:手机电源管理模块、智能穿戴射频前端,0201封装适配小尺寸PCB;
  3. 工业控制模块:PLC输入输出接口、电机驱动辅助电路,宽温范围适应现场温度波动;
  4. 小型医疗设备:血糖仪、血氧仪信号处理单元,低功耗(50mW)符合电池供电需求。

五、品牌与选型优势

UNI-ROYAL(厚声)作为国内电阻行业龙头,0201WMF4704TEE具有以下优势:

  • 成本效益:厚膜工艺比薄膜电阻成本低30%~40%,适合中低端通用场景;
  • 供货稳定:月产能达千万级,可满足家电、消费电子大规模量产需求;
  • 定制灵活:支持小批量定制(如阻值微调、包装方式),适配小众应用。

注意:该产品未标注汽车级认证(AEC-Q200),若用于车载场景需确认厚声汽车级衍生型号。

综上,0201WMF4704TEE是一款性价比突出的小体积高精度厚膜电阻,适合对尺寸、精度、宽温有要求的通用信号电路设计。

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
