  • 生产品牌:PANASONIC(松下)
  • 电阻类型:厚膜贴片电阻
  • 封装规格:0402(英制,对应公制1005)
  • 核心阻值:374kΩ(阻值编码规则:前三位为有效数字「374」,第四位为倍率「10³」)
  • 功率等级:100mW(0.1W)

二、核心电气性能参数

  1. 阻值精度:±1%
    满足工业级及消费电子对信号精准度的需求,可有效避免电路中因阻值偏差导致的信号偏移、增益异常等问题。

  2. 温度系数(TCR):±100ppm/℃
    温度每变化1℃,阻值变化量约为37.4Ω(374kΩ×100ppm),在宽温区下保持阻值稳定性,适配高低温交替的工作环境。

  3. 功率与电压特性:

    • 额定功率:100mW(全温区范围内可稳定承载);
    • 最大工作电压:约193V(由公式( V=\sqrt{P×R} )计算,( P=0.1W )、( R=374kΩ )),满足常规电路电压需求。

三、封装与物理特性

0402封装尺寸紧凑,公制规格为1.0mm(长)×0.5mm(宽)×0.35mm(厚),重量仅约0.01g,支持PCB高密度集成,尤其适用于小型化电子设备(如智能手机、可穿戴设备、小型工业传感器)。

封装采用陶瓷基片+厚膜电阻层结构,表面平整,兼容自动贴装(SMT)工艺,贴装效率高,焊点可靠性强,可降低量产中的焊接不良率。

四、适用场景与应用优势

1. 典型应用场景

  • 消费电子:智能手机、平板电脑、蓝牙耳机等终端的信号调理电路;
  • 工业控制:传感器信号放大、PLC模块、电机驱动辅助电路;
  • 通信设备:基站射频前端、光纤收发器的偏置电路;
  • 汽车电子:车载信息娱乐系统、低功耗传感器接口电路。

2. 核心应用优势

  • 小型化集成:0402封装缩小产品体积,适配轻薄化设计趋势;
  • 宽温稳定:-55℃~+155℃温区覆盖工业级及部分汽车电子场景;
  • 高可靠性:厚膜工艺抗机械应力、抗潮湿,长期工作性能稳定;
  • 成本可控:成熟量产工艺下,性能与成本平衡,适合大规模应用。

五、可靠性与环境适应性

  1. 环境耐受能力:

    • 温度范围:-55℃至+155℃,可在极端高低温环境下持续工作(如户外工业传感器、高温车间设备);
    • 湿度:符合IEC 60068-2-67标准,抗潮湿能力强,避免阻值漂移;
    • 机械性能:抗振动(10~2000Hz,加速度1g)、抗冲击(1000m/s²),满足运输及现场振动场景。
  2. 长期可靠性验证:

    • 负载寿命:125℃/额定功率条件下,工作1000小时后阻值变化率≤±0.5%(典型值);
    • 耐浪涌:可承受1.5倍额定电压/2倍额定功率的浪涌冲击(10次循环),阻值变化率≤±1%。

六、品牌与质量保障

松下作为全球电子元器件龙头,ERJ2RKF3743X遵循严格的质量管控体系,符合RoHS、REACH等环保标准,采用无铅封装(符合IEC 61249-2-21)。产品出厂前经全参数测试,确保性能一致性,广泛应用于全球知名企业的量产项目,获得行业高度认可。

总结

ERJ2RKF3743X凭借紧凑封装、精准阻值、宽温稳定及高可靠性,成为小型化电子设计中厚膜贴片电阻的优选方案,适配多领域电子设备的性能需求,兼顾量产效率与成本控制。

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
