ERA2AEB201X 薄膜贴片电阻产品概述

1. 产品定位与核心身份

ERA2AEB201X是松下(PANASONIC) 推出的高精度小功率薄膜贴片电阻,属于其工业级电阻系列的核心型号。型号编码中:

  • “ERA”为松下薄膜电阻系列标识;
  • “2A”对应0402封装规格;
  • “EB”代表精度等级(±0.1%)与温度系数(±25ppm/℃);
  • “201”为阻值代码(20×10¹=200Ω);
  • 尾缀隐含无铅环保设计。

该产品针对高密度集成、宽温稳定、高精度要求的电路场景,是便携式电子、工业控制等领域的常用选型。

2. 核心电气参数详解

2.1 阻值与精度

阻值固定为200Ω,精度达**±0.1%**——这一精度远高于普通厚膜电阻(通常±1%~±5%),可直接应用于测试仪器、医疗设备等对阻值误差敏感的场景,避免因偏差导致信号失真或控制精度下降。

2.2 功率与电压限制

  • 额定功率:63mW(25℃环境温度下);
  • 额定工作电压:50V。

需注意实际使用限制:需同时满足「功率≤63mW」和「电压≤50V」,例如当电压达50V时,功耗为50²/200=12.5W(远大于63mW),此时需以功率为核心,实际工作电压需控制在≈3.56V以内(√(63mW×200Ω))。

2.3 温度系数(TCR)

温度系数为**±25ppm/℃**,即温度每变化1℃,阻值变化5μΩ(200Ω×25×10⁻⁶)。这一参数表现优异,远优于厚膜电阻(通常±100ppm/℃以上),确保宽温环境下阻值稳定性。

3. 封装与功率降额特性

3.1 封装规格

采用0402封装(英制:1.0mm×0.5mm;公制:1005),是小型化贴片电阻的主流封装之一,可显著提升PCB集成密度,适配智能手机、可穿戴设备等对空间要求严苛的产品。

3.2 功率降额要求

薄膜电阻的功率能力随温度升高下降,需遵循松下降额标准:

  • 25℃~125℃:每升高1℃,额定功率降额≈0.4mW(125℃时约23mW);
  • 125℃~155℃:降额速率调整,155℃时额定功率约13mW。

实际应用需结合工作温度,避免功率过载导致性能失效。

4. 宽温稳定性表现

工作温度范围覆盖**-55℃~+155℃**,满足工业级环境要求(如汽车电子、户外设备的极端温度场景)。结合±25ppm/℃的TCR,全温度范围内阻值最大变化量为:
200Ω×25ppm/℃×210℃(-55℃→155℃温差)=1.05Ω,相对变化仅0.525%。

叠加±0.1%的精度后,整体阻值偏差控制在±0.625%以内,稳定性远超行业平均水平。

5. 适用场景与品牌优势

5.1 典型应用场景

  • 便携式电子:智能手机、智能手表的传感器前端、音频滤波电路;
  • 工业控制:PLC模拟量输入模块、温度传感器信号放大电路;
  • 通信设备:基站射频匹配网络、光纤收发器偏置电路;
  • 测试仪器:高精度万用表、示波器的校准电阻网络。

5.2 核心优势

  • 松下品质:采用成熟薄膜沉积工艺,电阻一致性好,MTBF(平均无故障时间)达数百万小时;
  • 低噪声特性:电流噪声典型值<0.1μV/√Hz,适合低噪声放大电路;
  • 环保合规:符合RoHS、REACH标准,满足全球市场准入要求。

该产品以高性价比平衡了精度、稳定性与集成度,是小型化电路设计的可靠选型。

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
