1206W4F3301T5E 产品概述

一、产品简介

1206W4F3301T5E 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,封装尺寸为 1206(约 3.2 mm × 1.6 mm)。标称阻值 3.3 kΩ,精度 ±1%,额定功率 250 mW,最高工作电压 200 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该器件面向通用电子线路,兼顾成本与稳定性,适用于批量贴装的表面贴装工艺。

二、主要电气参数

  • 阻值:3.3 kΩ(标称)
  • 阻值精度:±1%
  • 额定功率:250 mW(在规定环境与散热条件下)
  • 最高工作电压:200 V
  • 温度系数:±100 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃

这些参数决定了器件在常见信号处理、偏置网络、分压器及终端匹配等场景中的可用性与稳定性。

三、封装与机械特性

  • 封装:1206(公认尺寸约 3.2 × 1.6 mm),适合自动贴片生产线。
  • 安装方式:表面贴装(SMT),通常以卷带(Tape & Reel)形式供货,便于高速贴装。
  • 结构:厚膜工艺,电阻膜沉积在陶瓷基片上,外层有保护釉。厚膜电阻具备良好的冲击与耐焊性,成本较低。

四、典型应用场景

  • 模拟与数字电路中的分压器、限流、偏置与拉低/上拉电阻。
  • 工业控制、家电、照明驱动以及消费电子等对可靠性与成本有平衡要求的产品。
  • 由于额定电压较高,也可用于高电压分压或测量前端(在满足功率与热管理要求下)。

五、使用与焊接注意事项

  • 焊接:兼容常规 SMT 回流焊工艺(请参照具体回流曲线,避免超出封装允许的峰值温度与时间)。
  • 散热与降额:额定 250 mW 为在特定环境及散热条件下的功率值。实际使用时须考虑 PCB 铜箔面积、器件间距及环境温度对散热的影响,并依厂商给出的功率-温度特性曲线进行降额设计。
  • 温度稳定性:TCR ±100 ppm/℃ 表明随温度变化阻值会有一定偏移,应在精密测量或温漂敏感的场合做好补偿或选用更低 TCR 的器件。
  • 贮存与防潮:建议按一般 SMD 元件防潮存放,必要时在回流前进行烘烤处理以避免焊接缺陷。

六、选型与替代建议

  • 若需更低温漂或更高精度,可考虑薄膜电阻或更高精度(±0.1% / ±0.5%)系列产品。
  • 若功率或耐焊性要求更高,可选用更大封装(如 2010/2512)或金属膜、金属氧化膜等类型。
  • 在高频应用中,注意厚膜电阻的寄生电感与电容特性,必要时选择专用低寄生型号。

七、可靠性与质量说明

UNI-ROYAL(厚声)厚膜系列经过量产验证,适配自动化 SMT 生产流程,性能稳定、批次一致性良好。对于关键应用建议与供应商确认具体的可靠性测试数据(如温度循环、湿热、焊接耐受性及寿命试验),并在设计初期进行样片验证。

如需更详细的封装尺寸图、功率-温度曲线、回流焊推荐曲线或PCB焊盘建议,请告知用途与工作条件,我可以提供针对性的设计建议。

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
