0402WGF470KTCE 贴片厚膜电阻产品概述

一、核心参数总览

0402WGF470KTCE是UNI-ROYAL(厚声)推出的小型化贴片厚膜电阻,核心参数清晰适配常规电子电路需求:

  • 阻值:4.7Ω(标称值,精度±1%)
  • 精度等级:±1%(工业常用精度,满足多数电路匹配需求)
  • 额定功率:62.5mW(0402封装常规功率规格,适配低功耗场景)
  • 封装形式:0402(英制尺寸,对应公制1005,体积仅1.0mm×0.5mm)
  • 温度系数:±200ppm/℃(宽温范围内阻值稳定性良好)
  • 工作温度:-55℃~+155℃(覆盖工业级及部分汽车级环境)
  • 最大工作电压:50V(中低压电路安全范围)
  • 电阻类型:厚膜电阻(厚膜印刷工艺,成本与性能平衡优异)

二、产品特性解析

该电阻的设计特性贴合多场景需求,核心优势体现在:

  1. 宽温可靠性:±200ppm/℃的温度系数可满足极端温度波动(如155℃时阻值漂移约2.6%,虽略超标称精度,但宽温下性能仍稳定),适配工业现场低温启动或高温运行。
  2. 小型化高密度:0402封装大幅降低PCB布局面积,适合智能手机、智能穿戴等对尺寸敏感的设备,可提升电路集成度。
  3. 成本与性能平衡:厚膜工艺相较于薄膜电阻成本更低,同时±1%精度、62.5mW功率覆盖80%以上常规电路需求,无需过度设计。
  4. 中低压兼容:50V最大工作电压适配3.3V/5V电源电路、信号调理链路,无需额外降额设计。

三、典型应用场景

结合参数特性,该电阻主要适用于以下领域:

  • 消费电子:智能手机、平板电脑的电源滤波、音频信号分压网络,满足小型化与低功耗需求。
  • 工业控制:传感器信号采集链路(温度/压力传感器调理)、PLC输入输出限流电阻,宽温范围适配工业现场环境。
  • 物联网终端:BLE/ZigBee无线模块偏置电路、PMU反馈电阻,62.5mW功率匹配终端低功耗设计。
  • 汽车电子辅助电路:车载信息娱乐系统信号处理(非安全关键件),覆盖-40℃~+85℃车载温度波动。

四、品牌与品质保障

UNI-ROYAL(厚声)作为国内被动元器件龙头厂商,该产品具备可靠品质:

  • 工艺一致性:自动化厚膜印刷+烧结工艺,批量产品参数离散性小,符合IPC-A-610组装标准。
  • 环保合规:符合RoHS 2.0、REACH法规,无铅无卤设计,适配绿色电子趋势。
  • 可靠性验证:通过高低温循环、湿热老化、振动冲击测试,典型MTBF超10万小时,满足长期使用需求。

五、选型与使用注意事项

为确保电路性能,使用时需注意:

  1. 功率降额:实际功率建议≤额定值的70%(≤43.75mW),避免过热导致阻值漂移。
  2. 焊接工艺:需采用回流焊(峰值温度240℃260℃,回流时间3060秒),避免手工焊接虚焊。
  3. 温度系数考量:极端温度场景下(如-55℃/155℃),需验证阻值变化对精密电路的影响。
  4. 电压限制:严禁超50V工作电压,避免绝缘层击穿短路。

该产品以高性价比、宽温稳定的特性,成为消费电子、工业控制等领域小型化电路的优选被动元件。

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
