  • 电阻类型:厚膜贴片电阻(陶瓷基片+丝网印刷电阻浆料烧结而成,兼顾成本与可靠性)。

3. 标识解析

  • 1206:封装尺寸代码;
  • W:功率等级标识(对应250mW/1/4W);
  • J:精度等级(EIA标准,J=±5%);
  • 0751:阻值编码(75×10¹=750Ω);
  • T5E:厚声内部参数/批次标识(保证一致性)。

二、核心电性能参数

1. 阻值与精度

  • 标称阻值:750Ω(E24系列通用阻值,满足多数分压、限流需求);
  • 精度:±5%(无需高精度场景的经济选择,批量一致性好)。

2. 功率与电压

  • 额定功率:250mW(1/4W)——持续工作功率,短时过载能力符合厚膜电阻标准(可承受短时间1.5~2倍额定功率脉冲);
  • 最大工作电压:200V(直流/交流峰值)——避免电路电压超限导致击穿,适配中低压电源、信号调理电路。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃——温度每变化1℃,阻值变化≈±0.075Ω(750Ω×10⁻⁶),满足宽温环境下的性能稳定需求;
  • 工作/存储温度:-55℃+155℃——覆盖工业级(-40℃+125℃)及汽车级(-40℃~+150℃)环境。

三、物理与环境适应性

1. 封装尺寸与焊接

  • 尺寸:长3.2mm×宽1.6mm×厚0.5mm(典型值),符合IPC-J-STD-001焊接标准;
  • 焊接兼容性:支持回流焊(峰值温度260℃±5℃,时间≤10s)、波峰焊(峰值温度245℃±5℃,时间≤3s),无铅焊接工艺适配。

2. 耐环境性能

  • 湿度适应性:可在相对湿度5%~95%(无凝露)环境下长期工作;
  • 机械强度:陶瓷基片抗冲击、抗振动(符合IEC 60068-2-6振动测试标准),适合车载、工业设备等振动场景。

四、典型应用场景

  1. 消费电子:智能手机/平板的电源滤波、信号分压电路;智能音箱、智能家居温控器的限流电阻;
  2. 工业控制:PLC输入输出接口的匹配电阻;传感器信号放大电路的偏置电阻;
  3. 汽车电子:车载显示屏背光驱动、倒车雷达信号滤波(满足-40℃~+125℃汽车级温度);
  4. 通信设备:路由器/交换机的电源稳压、射频前端低功率匹配网络。

五、产品优势

  1. 成本与性能平衡:厚膜工艺降低成本,±5%精度适配通用场景,无需过度设计;
  2. 宽温可靠性:-55℃~+155℃工作范围,覆盖工业、汽车等严苛环境;
  3. 批量一致性:UNI-ROYAL成熟工艺保证批量产品阻值、功率偏差符合规格,降低电路调试难度;
  4. 环保合规:无铅、无卤素设计,符合全球环保法规要求。

1206W4J0751T5E以其稳定的电性能、宽温适应性及高性价比,成为通用电路设计中替代进口同类产品的优质选择,尤其适合对成本敏感且需宽温工作的应用场景。

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
