0603WAF3903T5E 产品概述

一、产品简介

0603WAF3903T5E 为 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装为 0603(1608 公制),阻值 390kΩ,精度 ±1%。该器件面向对体积、可靠性与成本有平衡要求的表面贴装电路,适用于滤波、偏置、分压及高阻抗测量等场景。典型标称参数如下,便于在设计环节快速判断是否满足需求。

二、主要性能参数

  • 电阻类型:厚膜电阻(Thin/Thick film:厚膜)
  • 阻值:390 kΩ
  • 精度:±1%(1/100)
  • 额定功率:100 mW
  • 工作电压:75 V(最大)
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0603(1608公制)
  • 品牌:UNI-ROYAL(厚声)
  • 描述:贴片电阻 0603 390KΩ ±1%

三、关键特性与优势

  • 高阻值与紧凑封装:在 0603 小型化封装下实现 390kΩ,适合对空间要求较高的便携或密集 PCB 布局。
  • 精度较高:±1% 精度满足大多数模拟、测量及分压场景的稳定性要求。
  • 宽温度范围:-55 ℃ 至 +155 ℃,适合工业级及温度波动较大的应用环境。
  • 可接受的 TCR:±100 ppm/℃ 在中高精度电路中表现平衡,尤其适用于对温漂有一定容忍度的场合。
  • 标称工作电压 75V,适用于中低电压分压/偏置电路;高压需求可通过并联/串联设计实现。

四、典型应用

  • 模拟前端的偏置与分压网络(放大器偏置、电阻分压)
  • 高阻抗信号的滤波与耦合电路(与电容形成 RC 滤波)
  • 便携式与消费电子设备中占板面积受限的电路
  • 工业控制与测量仪表中对温度范围要求较高的节点

五、封装与可靠性

0603 封装支持高速贴装(贴片机与回流焊工艺),常见卷带(Tape & Reel)包装,便于SMT自动化生产。厚膜工艺具有良好的机械强度与耐焊性,但在焊接和后处理过程中仍需避免过度机械应力与化学侵蚀以维持长期可靠性。

六、使用建议

  • 功率与温度降额:额定功率为 100 mW,在升高环境温度下需按厂方或通用降额曲线进行功率限制,避免长期超额散热导致漂移或失效。
  • 电压限制:单个元件最大工作电压 75 V,超过时应采用串联电阻或选用更高电压等级器件。
  • 焊接工艺:建议采用常见回流焊工艺,遵循设备与材料的温度上限,避免反复多次高温循环。
  • 贴装与机械应力:贴片过程中避免在端帽处施加过大挤压或弯曲力,清洁时使用对厚膜安全的溶剂和工艺。

七、储存与质量合规

  • 储存环境应干燥、无腐蚀性气体、避免阳光直射,推荐室内常温、相对湿度受控的环境。
  • 典型供应形式为卷带包装,便于追溯与生产控制。
  • 具体可靠性、寿命与环境试验结果(如湿热、温变、寿命加速试验)建议参照 UNI-ROYAL 提供的产品数据手册与认证资料进行验证。

如需更详细的电气特性曲线、功率降额表、焊接曲线或可靠性测试报告,可提供数据手册或样品进行实际评估,以保证在目标应用中的长期性能与可靠性。

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
