ERA3AEB4021V 产品概述

一、产品基本信息

  • 型号:ERA3AEB4021V
  • 品牌:PANASONIC(松下)
  • 产品类型:精密薄膜贴片电阻
  • 封装规格:0603(英制:60mil×30mil;公制:1.6mm×0.8mm)
  • 核心工艺:真空溅射薄膜工艺

二、核心性能参数

  1. 阻值与精度:标称阻值4.02kΩ,精度±0.1%——属于工业级精密电阻,可满足信号调理、反馈网络等对阻值一致性要求苛刻的场景(如传感器校准电路);
  2. 功率与电压:额定功率100mW,最大工作电压75V——在0603封装中为常规功率规格,实际使用需遵循降额设计(建议负载功率不超过70mW,避免热老化导致阻值漂移);
  3. 温度系数(TCR):±25ppm/℃——薄膜电阻的典型低温度系数,意味着温度每变化1℃,阻值变化仅约±0.1005Ω(4.02kΩ×25ppm),宽温环境下稳定性优异;
  4. 工作温度范围:-55℃至+155℃——覆盖工业级、车载电子(部分场景)的温度需求,可适应高低温交替的恶劣环境。

三、薄膜电阻技术特点

  1. 工艺优势:采用真空溅射工艺形成电阻膜,相比厚膜电阻(丝网印刷),膜层更均匀致密,阻值一致性提升30%以上;
  2. 低噪声特性:电流噪声约0.1μV/V(典型值),远低于厚膜电阻(通常>1μV/V),适合音频、射频等对噪声敏感的电路;
  3. 高频性能:0603封装寄生电感约0.5nH、寄生电容约0.05pF,可支持1GHz以上的高频应用(如基站射频匹配网络);
  4. 长期稳定性:额定条件下工作1000小时,阻值变化率<0.1%,远优于厚膜电阻的<0.5%,适合医疗仪器、工业控制器等长寿命设备。

四、典型应用场景

  1. 工业控制:PLC模拟量输入模块的分压网络、压力/温度传感器的信号调理电路;
  2. 通信设备:基站射频前端匹配网络、光纤收发器偏置电路;
  3. 医疗仪器:监护仪信号放大电路、血糖仪校准电阻网络;
  4. 消费电子:智能手机射频天线匹配、可穿戴设备传感器供电电路;
  5. 汽车电子:车载信息娱乐系统音频电路、胎压监测模块信号处理电路(需结合整车级认证场景)。

五、可靠性与环境适应性

  1. 耐温测试:通过-55℃~+155℃循环100次测试,阻值变化<0.1%;
  2. 耐湿性:符合IEC 60068-2-67湿负荷标准,85℃/85%RH环境下工作1000小时,阻值变化<0.2%;
  3. 机械强度:焊接可靠性达JIS C 5102标准,1.5m跌落10次无开路/短路,适合便携式设备;
  4. 环保合规:符合RoHS、REACH标准,无铅焊接兼容(回流焊温度≤260℃)。

六、选型与使用注意事项

  1. 同参数替代:
    • 小封装:ERA2AEB4021V(0402封装,功率50mW);
    • 大功率:ERA3AEB4021X(0603封装,功率200mW);
  2. 精度调整:
    • 更高精度(±0.05%):ERA3AEB4021A;
    • 低成本替代(±1%):厚膜电阻ERJ-2RKF4021X;
  3. 使用禁忌:
    • 避免超过最大工作电压75V;
    • 焊接时禁止使用烙铁直接接触电阻体(易损坏薄膜)。

总结:ERA3AEB4021V作为松下精密薄膜电阻,凭借±0.1%精度、±25ppm/℃温漂及宽温适应性,成为工业、通信、医疗等领域精密电路的核心选型,尤其适合对阻值稳定性要求高的小型化设备。

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
