0402WGF3003TCE 产品概述

一、产品简介

0402WGF3003TCE 为 UNI-ROYAL(厚声)品牌的贴片厚膜固定电阻,阻值 300kΩ,精度 ±1%,封装为 0402(公制 1005)。该器件针对空间受限和高阻值电路设计,具有宽工作温度范围和稳健的工艺特性,适合工业级与消费类电子产品中的高阻抗偏置、测量与滤波回路。

二、主要参数

  • 电阻类型:厚膜电阻
  • 阻值:300kΩ(4 位编码 3003 表示 300 × 10^3 Ω)
  • 精度:±1%
  • 额定功率:62.5 mW
  • 阶段工作电压:最大 50 V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0402(约 1.0 × 0.5 mm)

三、性能特点

  • 高频率稳定性与电阻线性良好,适合精密偏置与分压场合
  • ±1% 精度满足一般精密电子应用需求
  • ±100 ppm/℃ 的温漂在厚膜工艺中属常见水平,可保持中等温度稳定性
  • 小体积封装适合高密度贴片组装,适配自动化回流焊工艺
  • 相较于金属膜电阻,厚膜电阻工艺成本低、可批量稳定供应

四、典型应用

  • 模拟电路中的偏置与上拉/下拉电阻(高阻值要求场合)
  • ADC/DAC 输入高阻源与采样网络
  • 传感器信号 conditioning、滤波与漏电流控制
  • 手持设备、便携仪器及工业控制模块中的高阻值网络

五、封装与焊接

0402 封装适用于标准 SMD 贴片与回流焊流程。建议遵循厂商焊接曲线与回流温度上限,避免超温或长时间保温以减少电阻漂移。表面处理与贴装方向对可靠性有一定影响,批量生产建议做首件与老化验证。

六、选型与注意事项

  • 额定功率 62.5 mW 为典型室温下测得值,高温环境需按降额使用并参考实际热阻条件;长时间接近额定功率会影响寿命与漂移。
  • 工作电压不得超过 50 V,以免击穿或绝缘失效。
  • 对噪声、长期稳定性有更高要求的场合,考虑金属膜或薄膜电阻替代。
  • 在高湿或化学环境中使用时,应评估封装密封与清洗工艺对可靠性的影响。

七、品牌与订购提示

UNI-ROYAL(厚声)为工业级被动元件供应商,0402WGF3003TCE 适合需要小型化与高阻值的标准设计。订购时请确认批次、包装卷带(reel)规格和焊接推荐曲线,并向供应商索取完整数据手册与可靠性测试报告以便做最终验证。

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
