0402WGF3902TCE 产品概述

一、产品概述

0402WGF3902TCE 是 UNI-ROYAL(厚声)出品的一款 0402 封装厚膜贴片电阻,标称阻值 39 kΩ,精度 ±1%,额定功率 62.5 mW(1/16W),最大工作电压 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该器件面向对体积和成本有严格要求的消费电子与工业控制类应用,适合在高密度 PCB 上实现精确阻值需求。

二、主要参数

  • 类型:厚膜贴片电阻(Thick film chip resistor)
  • 封装:0402(约 1.0 mm × 0.5 mm)
  • 阻值:39 kΩ
  • 精度:±1%
  • 额定功率:62.5 mW(室温条件下)
  • 最大工作电压:50 V(接近该电压时器件耗散功率接近额定值,应留裕量)
  • 温度系数:±100 ppm/℃(约 0.01%/℃)
  • 工作温度:-55℃ ~ +155℃
  • 品牌:UNI-ROYAL(厚声)
  • 型号:0402WGF3902TCE

三、产品特点

  • 小型化封装 0402,适用于高密度 SMT 设计。
  • ±1% 精度满足多数模拟电路、分压与滤波网络的精确性要求。
  • ±100 ppm/℃ 的温漂性能在普通工业与消费类应用中可接受,温度引起的阻值变化约为 0.01%/℃(例如 100℃ 温差约引起 1% 变动)。
  • 厚膜制造工艺兼顾成本与稳定性,批量一致性良好。
  • 额定工作电压与功率适合低功耗信号链与参考网络使用,但在高压/高功耗场合需做降额处理。

四、典型应用

  • 精密分压器、基准电路与滤波网络。
  • 微弱信号前端与放大器偏置电阻。
  • 移动设备、可穿戴设备与物联网终端中的通用阻值需求。
  • 工业控制、测量设备中的非高精度阻值配套元件。

五、封装与安装注意事项

  • 0402 封装体积小,贴装时需使用精密取放设备并注意焊膏量控制。
  • 与常见回流焊工艺兼容,但建议参照厂商回流曲线,避免过高峰温或过长加热时间以免影响电阻稳定性。
  • 存储与贴装前注意防潮、防静电处理,避免受潮导致焊接不良或元件性能下降。
  • 在 PCB 设计时为保证散热与功率余量,应避免将高发热器件紧邻多个高功率元件叠放。

六、选型与使用建议

  • 若工作电压接近 50 V 或长期在高温环境使用,应留有足够的功率裕量或选择更高功率/更高电压等级的器件,避免长期满载运行。
  • 对温漂与长期稳定性有更高要求的场合,可考虑金属膜或低 TCR(≤25 ppm/℃)的元件。
  • 在精密测量或校准电路中,需将 ±1% 容差与温度引起的阻值变化一并纳入误差预算。

总结:0402WGF3902TCE 以其小型化封装和 ±1% 精度,适合大多数需要节省 PCB 空间且对成本敏感的模拟与数字电路。如果设计中涉及较高电压或长期高温工作,请在选型时考虑适当降额或选用更高规格的器件。若需完整数据手册或回流焊工艺曲线,建议向 UNI-ROYAL 厚声索取官方资料。

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
