0402WGF5621TCE 厚膜贴片电阻产品概述

一、产品基本属性

0402WGF5621TCE是UNI-ROYAL(厚声)推出的厚膜贴片电阻,采用行业通用的0402封装(英制尺寸,对应公制1005,即1.0mm×0.5mm),针对小型化、高密度PCB设计优化。其核心电参数清晰明确:

  • 标称阻值:5.62kΩ(电阻代码“5621”,前三位有效数字562,第四位倍率10¹);
  • 精度等级:±1%,满足多数电路对阻值偏差的基础要求;
  • 额定功率:62.5mW(0.0625W),典型工作场景下功率余量充足;
  • 最大工作电压:50V,避免高压击穿风险;
  • 温度系数(TCR):±100ppm/℃,宽温范围内阻值漂移可控;
  • 工作温度范围:-55℃至+155℃,覆盖工业级环境温度需求。

二、技术特性与核心优势

该产品依托厚声成熟的厚膜印刷工艺,兼具小体积、高稳定、高可靠等特点:

  1. 宽温区阻值稳定性:-55℃~+155℃的工作范围适配工业、车载(部分场景)及户外设备,±100ppm/℃的TCR确保100℃温差下阻值偏差≤0.2%,避免电路性能波动;
  2. 高密度小型化设计:0402封装体积仅1.0mm×0.5mm,可大幅提升PCB布线密度,适配智能手机、智能穿戴等便携设备的空间限制;
  3. 厚膜工艺可靠性:电阻膜层采用“印刷+烧结”工艺,附着力强、抗机械冲击,长期使用无阻值漂移或开路风险,符合电子设备长寿命要求;
  4. 精准阻值控制:±1%精度可满足信号调理、电源分压、限流等电路的精准需求,无需额外校准;
  5. 环保与兼容性:符合RoHS、REACH标准,无铅无卤,适配全球市场环保要求,同时兼容主流焊接工艺(回流焊、波峰焊)。

三、典型应用场景

0402WGF5621TCE因参数适配性强,广泛应用于以下领域:

  1. 便携式电子设备:智能手机、智能手表、蓝牙耳机等产品的信号滤波、电源管理(如LDO输出分压)、传感器接口电路;
  2. 工业控制模块:PLC输入输出接口、小型传感器(温度/压力)信号调理电路,适应-55℃~+155℃的工业环境;
  3. 消费类智能家居:智能插座、温湿度传感器节点、小型家电(加湿器/智能灯)控制板基础电阻;
  4. 通信设备:小型基站、路由器、WiFi模块的射频前端匹配、电源滤波电路;
  5. 汽车电子辅助电路:车载USB充电模块、车内座椅传感器辅助电路(需确认具体场景温度要求)。

四、可靠性与质量保障

厚声作为国内知名电阻制造商,对该产品的质量管控严格:

  • 体系认证:生产过程通过ISO9001质量管理体系认证,产品一致性达标率≥99.5%;
  • 环保认证:符合RoHS 2.0、REACH SVHC要求,无有害物质残留;
  • 老化测试:出厂前经125℃高温老化24小时,筛选早期失效产品,确保长期稳定性;
  • ESD防护:电阻膜层及封装具备抗静电能力,符合IEC 61340静电防护标准。

五、使用注意事项

为确保产品性能与寿命,使用时需注意:

  1. 焊接工艺:回流焊峰值温度≤260℃(时间≤10秒),波峰焊温度≤250℃(时间≤5秒),避免热应力损坏;
  2. 静电防护:操作时佩戴静电手环/手套,使用静电防护工作台,防止ESD导致阻值突变;
  3. 功率降额:125℃以上工作时,按厚声降额曲线降低功率(如155℃时降额至50%);
  4. 储存条件:未开封产品储存在1535℃、湿度40%60%环境中,开封后1个月内使用完毕,避免潮湿氧化引脚。

总结

0402WGF5621TCE是一款高性价比厚膜贴片电阻,平衡了小体积、宽温稳定、精准阻值与可靠性,适配多数中低端至中端电子设备的基础电阻需求,是便携式、工业控制等领域的优选元件。

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
