0402WGF4303TCE 厚膜贴片电阻产品概述

一、产品核心身份与定位

该电阻为UNI-ROYAL(厚声)推出的0402封装厚膜贴片电阻,型号0402WGF4303TCE,属于小功率高精度高阻值系列。其设计聚焦“小型化+高可靠性”,适配高密度电路布局需求,兼顾成本与性能,可覆盖消费电子、工业控制等多领域应用。

二、关键电气性能参数

这款电阻的核心电气参数清晰可落地,能满足多数电路的基础需求:

  • 阻值与精度:430kΩ(对应贴片代码“4303”,前两位“43”为有效数字,第三位“3”表示10³倍,即43×10³=430kΩ),精度±1%——无需额外校准即可适配信号调理、分压等场景;
  • 功率与电压:额定功率62.5mW(0402封装典型小功率规格),工作电压50V;使用时需遵循降额原则(如环境温度>100℃时,实际功率建议不超额定值的80%),避免热失效;
  • 温度系数:±100ppm/℃——温度每变化1℃,阻值变化约0.01%,宽温下性能稳定,不会因温度波动导致电路漂移。

三、封装与工艺特性

  • 封装尺寸:0402英制封装(公制约1.0mm×0.5mm×0.5mm),体积仅为常规插件电阻的1/10左右,适合PCB板高密度布局,可有效缩小产品整体尺寸;
  • 制造工艺:采用厚膜工艺(丝网印刷电阻浆料于氧化铝陶瓷基底,经1000℃以上高温烧结而成)——该工艺成本低、一致性好,电阻膜附着力强,抗机械应力能力优于薄膜电阻,适合批量生产;
  • 贴装适配性:贴片式设计,兼容自动化贴装设备(如富士、西门子贴片机),生产效率提升3倍以上,减少人工成本,适合大规模量产。

四、环境适应性表现

该电阻的工作温度范围为**-55℃至+155℃**,覆盖大部分工业场景的极端温度需求:

  • 低温端:可应对东北、俄罗斯等低温地区的户外传感器、车载电子(冬季低温);
  • 高温端:能在工业烤箱(≤155℃)、高温环境监测设备中稳定工作,无需额外散热;
  • 耐温稳定性:厚膜电阻膜在宽温下阻值漂移<0.5%(-55~155℃全温区),符合工业级器件的可靠性要求。

五、典型应用场景

基于“小体积+高精度+宽温适应”的特点,该电阻可落地以下场景:

  1. 消费电子:智能手环、蓝牙耳机的信号调理电路(分压、限流),小型智能家居设备的控制模块;
  2. 工业控制:PLC输入输出模块的分压网络,传感器信号放大电路的偏置电阻,小型电机驱动电路的限流;
  3. 通信设备:小型基站、路由器的射频前端偏置电路,光纤收发器的信号衰减调节;
  4. 汽车电子:车载显示屏的背光控制电路,车门传感器的信号处理(-55~155℃可覆盖大部分车载工况);
  5. 医疗设备:小型血糖仪、血压计的信号采集电路,低功耗诊断仪器的电阻网络。

六、品牌与可靠性说明

UNI-ROYAL(厚声)是国内电阻制造领域的老牌厂商,产品符合RoHS、REACH等环保标准,无铅无镉,满足欧盟出口要求;
该电阻经过1000小时老化测试与批量一致性筛选,阻值偏差、温度系数等参数离散度<0.2%,长期使用中性能衰减<1%(10年寿命),可保证量产项目的稳定性。

综上,0402WGF4303TCE是一款“小而精”的厚膜贴片电阻,平衡了成本、性能与可靠性,适合对体积敏感、精度要求适中的电路设计。

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
