ERJ3GEYJ820V 贴片厚膜电阻器产品概述

ERJ3GEYJ820V是松下(PANASONIC)针对常规电路设计推出的0603封装贴片厚膜电阻器,凭借稳定的电气性能、紧凑的封装尺寸及宽温适应性,广泛应用于消费电子、工业控制、通信等领域的基础电路场景。

一、产品核心定位与工艺基础

该产品采用厚膜电阻工艺制造,通过在高纯度氧化铝陶瓷基底上印刷钌基电阻浆料并高温烧结而成,兼具成本优势与可靠性,属于松下ERJ系列常规精度贴片电阻的典型型号。核心用于电压分压、电流限流、信号匹配、负载偏置等非精密电路功能,无需额外校准即可适配多数量产设计需求。

二、关键电气性能参数详解

1. 阻值与精度

标称阻值为82Ω,精度等级±5%,满足常规电路对阻值匹配的基本要求。例如:

  • 在电源滤波电路中,该精度可有效抑制纹波干扰;
  • 在信号链路中,可完成阻抗匹配,避免信号反射导致的传输损耗。

2. 功率与电压能力

  • 额定功率:100mW(持续工作功率上限);
  • 最大工作电压:75V(峰值电压上限)。
    在额定功率范围内,电阻可稳定 dissipate 功率而无过热失效风险;电压上限覆盖低中压电路场景(如5V、12V、24V系统),避免过压击穿。

3. 温度系数(TCR)

温度系数为**±200ppm/℃**,即温度每变化1℃,阻值变化量为±82Ω×0.00002%=±0.0164Ω。在-55℃至+155℃的宽温范围内,阻值漂移可控,适合温度波动较大的环境(如户外工业设备、车载低温启动场景)。

三、物理封装与应用场景

1. 封装规格

采用0603封装(英制尺寸:0.06英寸×0.03英寸,对应公制1.6mm×0.8mm),体积小巧,适配高密度PCB布局,尤其适合便携式设备的小型化设计(如智能手机、智能穿戴)。

2. 典型应用场景

  • 消费电子:智能手机电源管理模块的滤波电阻、平板电脑信号调理电路的匹配电阻;
  • 工业控制:小型传感器模块的限流电阻、PLC辅助电路的分压电阻;
  • 通信设备:小型基站的信号链路匹配电阻、路由器的电源滤波电阻;
  • 汽车电子(低温区):车载低功耗电路的基础电阻(需注意高温持续工作的验证)。

四、环境可靠性与长期稳定性

1. 工作温度范围

覆盖**-55℃至+155℃**,满足工业级环境的温度要求(如低温启动、高温运行),无需额外增加温度补偿电路,降低设计成本。

2. 可靠性测试

产品经过松下严格的可靠性验证,包括:

  • 温度循环测试(-55℃~+155℃,循环次数≥1000次);
  • 湿度老化测试(85℃/85%RH,1000小时);
  • 振动冲击测试(符合IEC 60068-2-6标准);
    确保批量一致性与长期工作稳定性,无明显阻值漂移或失效风险。

五、品牌与品质保障

松下作为全球电子元器件领域的领先厂商,ERJ系列电阻采用标准化生产流程,原材料与工艺管控严格,产品符合IEC、JIS等国际标准,广泛应用于国内外主流电子厂商的量产产品中,可提供稳定的供应链支持与技术服务。

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
