1206W4J0271T5E 产品概述

一、产品概况

1206W4J0271T5E 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装尺寸为 1206(英制),阻值 270Ω,阻值精度 ±5%(J),额定功率 1/4W(250mW),适配常规贴片回流工艺。该型号在通用电子设计中以稳定的电气特性和良好的可靠性著称,适合需要中等功率、常温到高温环境下的电路阻抗元件使用。

二、主要技术参数

  • 电阻类型:厚膜电阻(薄膜/厚膜工艺差异已明确为厚膜)
  • 阻值:270Ω(标称)
  • 阻值精度:±5%(J)
  • 额定功率:250mW(1/4W)
  • 工作电压:200V(最大工作电压)
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:1206(尺寸符合业界 SMD 标准)
  • 品牌:UNI-ROYAL(厚声)

三、产品特性与优势

  • 温度适应性好:工作温度范围宽,可在-55℃ 至 +155℃ 条件下长期工作,适应工业级应用环境。
  • 热稳定性与功率承受力平衡:1/4W 的功率等级适合多数信号与弱功率电源回路,250mW 在 1206 封装中常见且可靠。
  • 可控温漂:±100 ppm/℃ 的温度系数在厚膜电阻中属于常用水平,满足多数通用精度要求。
  • 机械强度与焊接兼容:1206 封装便于自动贴装与回流焊,适配现代 SMT 生产线。

四、典型应用场景

  • 消费电子:电视、机顶盒、家用电器中分压、限流与阻抗匹配。
  • 工业控制:传感器接口、信号调理与接口保护电路。
  • 电源与照明:开关电源启动、负载分压与限流电阻(在额定条件下使用)。
  • 通信设备与仪器:匹配网络、基板级阻抗调节。

五、封装与安装注意事项

  • 推荐使用标准 SMT 回流焊工艺,严格控制回流峰值温度与时间窗以避免电阻膜层损伤。
  • 贴装时避免对元件施加过大机械压力或拉扯,以防内部裂纹导致阻值偏移或开路。
  • 清洗时选择对厚膜电阻安全的溶剂与工艺,避免长时间浸泡和过高温度清洗。
  • 存储建议:干燥、常温、避免潮湿与强光直射,长期存放宜采用原厂防潮包装。

六、订购信息与质量保障

型号标识中常见 271 表示三位数阻值编码(270Ω),T5E 类别多用于卷带包装与出货形式(以实际供应商标准为准)。UNI-ROYAL 提供批量出货、完整检验报告及出厂质量检测记录;如有特殊可靠性要求(如 AEC-Q 认证或更高精度、低 TCR 版本),建议提前与供应商确认型号与认证状态。若需样品测试或批量询价,可按具体使用环境和数量向代理或厂方技术支持咨询。

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
