0402WGF5104TCE 产品概述

一、产品简介

0402WGF5104TCE 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装为 0402(约 1.0 × 0.5 mm)。该器件阻值为 5.1 MΩ,公差 ±1%,额定功率 62.5 mW,额定工作电压 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。针对高阻值、占板面积受限且要求稳定性的应用进行了优化,适合高阻抗偏置、电压分压与测量前端等场景。

二、主要技术参数

  • 品牌:UNI-ROYAL(厚声)
  • 封装:0402(国际标准,约 1.0 × 0.5 mm)
  • 电阻类型:厚膜电阻
  • 阻值:5.1 MΩ
  • 精度:±1%
  • 额定功率:62.5 mW(静态散热条件下)
  • 额定工作电压:50 V(器件允许的最大施加电压)
  • 温度系数:±100 ppm/℃
  • 工作温度:-55℃ ~ +155℃

三、性能与限制说明

  • 高阻值适用于偏置与高阻抗测量回路,可显著减少泄漏电流对电路的影响。
  • 虽然额定功率为 62.5 mW,但由于阻值较大,从功耗角度计算达到该功率时对应电压约为 565 V(sqrt(P·R)),显著高于额定工作电压。因此实际使用中以额定工作电压 50 V 为限。
  • 在 50 V 条件下的实际电流与功耗:I = 50 V / 5.1 MΩ ≈ 9.8 μA,耗散功率约 0.49 mW,远低于额定功率。
  • TCR ±100 ppm/℃ 表明在温度变化时阻值有中等偏移,适合对温度漂移要求不是极致苛刻的高阻电路。

四、典型应用

  • 高阻抗输入级、传感器前端偏置电阻
  • 高压分压链(需注意额定工作电压限制)
  • 精密电路中需要小封装与较高阻值的场合
  • 模拟信号处理、测量仪器、移动设备与物联网终端中节省空间的电阻布局

五、安装与使用注意事项

  • 遵循标准 SMT 回流焊工艺,兼容主流无铅回流(峰值温度一般 ≤ 260℃);建议参考制造商的焊接曲线。
  • 避免在焊接或装配过程中对器件施加过大的机械应力,防止裂纹或电阻漂移。
  • 清洗时避免强溶剂或超声清洗对薄膜结构的潜在影响,必要时使用制造商推荐的清洗工艺。
  • 选型时以额定工作电压 50 V 为硬性限制,若电路存在瞬态或冲击电压需额外评估或采用更高电压等级器件。

六、包装与可靠性

  • 0402 封装有利于高密度贴装与自动化生产,常见卷带包装便于 SMT 贴片机直接上料。
  • 在正常工作环境与合理焊接条件下,厚膜电阻具有良好的焊接可靠性与环境适应性;对长期稳定性要求高的场合,建议结合温度循环与湿热试验结果做可靠性评估。

七、选型建议

  • 如果电路中电压接近或可能超过 50 V,应选用标称工作电压更高的电阻或考虑分压方式减少单个电阻承受电压。
  • 对温漂要求更严格的应用,可考虑金属膜或低 TCR 的薄膜电阻替代。
  • 在空间极度受限且电流很小的高阻电路中,0402WGF5104TCE 提供了兼顾体积与阻值的实用选择。

如需器件的封装图纸、回流焊温度曲线或更详细的可靠性试验数据,建议联系 UNI-ROYAL 厂家或代理商获取完整数据手册与工艺规范。

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
