0603WAF3902T5E 产品概述

一、产品简介

0603WAF3902T5E 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,封装尺寸为 0603(公制 1608),标称阻值 39kΩ,精度 ±1%。本品为通用 SMD 芯片电阻,适用于空间受限且对精度有一定要求的电子产品线路板设计。

二、主要技术参数

  • 电阻类型:厚膜电阻
  • 阻值:39kΩ
  • 精度:±1%(1%)
  • 功率额定:0.1W(100mW)
  • 最大工作电压:75V
  • 温度系数(TCR):±100ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0603(1608 公制)
  • 品牌:UNI-ROYAL(厚声)

三、产品特点

  • 小型化封装:0603 体积小,利于高密度 SMT 布局与节省 PCB 面积。
  • 精度稳定:±1% 精度满足多数模拟与数字电路的阻值配比需求。
  • 宽温度适应:-55℃ 至 +155℃ 工作范围,适合汽车电子、工业控制等苛刻环境(需与应用环境的热管理配合)。
  • 良好耐压与功率能力:75V 最大工作电压与 100mW 功率额定,可满足一般信号与分压场景。

四、典型应用

  • 信号处理与偏置网络(分压器、滤波、电平设定)
  • 工业控制与测量仪器的阻值匹配
  • 通信设备、消费电子的常规电阻需求
  • 采用空间受限的移动设备与 IoT 模组

五、焊接与使用建议

  • 建议采用标准无铅回流焊工艺,遵循 IPC/JEDEC 回流温度曲线,峰值温度不超过推荐范围(通常≤260℃)。
  • 焊接后避免长期超过额定功率与工作温度;在高温应用中请考虑功率降额与散热路径设计。
  • 储存与贴片前请保持干燥防潮,避免长期潮湿环境影响焊接性与可靠性。

六、可靠性与环境适应性

  • 厚膜工艺在潮湿与机械振动环境中表现稳定,常规可靠性试验(高温存储、温度循环、湿热试验)显示其在工业级与商用级场景下具有良好寿命表现。
  • 在极端或关键应用(汽车安全、医疗等)请选择具有相关认证与额外失效数据的产品型号。

七、包装与订购信息

  • 型号:0603WAF3902T5E(UNI-ROYAL)
  • 常见包装形式为卷带(Tape & Reel),便于高速贴片机使用。
  • 订购前请确认所需数量、回流工艺兼容性及是否需要特殊端接或认证,如 ROHS 要求或汽车级资格。

如需完整样品数据表(含阻抗-温度曲线、脉冲承受能力、焊接曲线与寿命测试数据),或具体应用级的降额建议,请提供应用场景与电路条件,以便给出更精确的选型与设计建议。

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
