ERJ1VM471F20OT直插铝电解电容产品概述

一、产品基本定位

ERJ1VM471F20OT是艾华集团(AISHI) 推出的一款通用型直插铝电解电容,聚焦中低压、中等容量的电路滤波与储能场景。作为艾华成熟产品线的核心成员,该电容以长寿命高温耐受为核心优势,适配消费电子、工业控制、通信设备等多领域的电源及信号处理需求,兼具体积紧凑、安装便捷的特点。

二、核心技术参数详解

该电容的参数覆盖典型应用场景,关键指标清晰明确:

  • 容值与精度:标称容量470μF(标注代码“471”,即47×10¹μF),精度±20%——符合铝电解电容常规精度标准,满足大多数电路对滤波、储能的偏差要求;
  • 额定电压:35V DC——支持中低压直流电路安全工作,需注意交流电压需核算峰值(如交流24V峰值约33.9V可安全使用,交流30V峰值超42V需避免);
  • 物理尺寸:电容体直径φ8mm(D8)、长度20mm(L20),引脚中心距3.5mm——体积紧凑,适配常规PCB焊盘布局,节省电路板空间;
  • 寿命与温度:10000小时@105℃——远高于普通铝电解电容(通常2000~5000hrs@105℃),高温环境下仍具备稳定可靠性;
  • 封装与品牌:直插式(插件)封装,艾华集团生产——插件引脚便于手工焊接与批量生产,焊盘兼容性好,降低虚焊风险。

三、产品设计特点

  1. 长寿命高温耐受:针对工业、电源等高温场景优化,105℃环境下持续工作10000小时,减少设备因电容老化导致的故障;
  2. 紧凑尺寸适配:φ8×20mm体积在同容量同电压等级中处于优势,适合小型化设备(如便携式电源、微型变频器);
  3. 通用型性能覆盖:470μF容值+35V电压组合,覆盖开关电源输出滤波、直流母线储能、信号耦合等典型场景;
  4. 可靠直插封装:插件引脚避免贴片电容的焊接精度要求,手工焊接可通过长脚识别极性,批量生产适配自动插件设备。

四、典型应用场景

该电容因性能适配性强,广泛应用于:

  • 开关电源:PC电源、LED驱动电源的12V/24V输出端滤波,稳定直流电压;
  • 工业控制:PLC、变频器、伺服驱动器的直流母线滤波,耐受工业环境高温与纹波;
  • 消费电子:显示器、机顶盒、智能家居设备的电源模块储能,满足小型化需求;
  • 通信设备:基站电源、路由器、交换机的滤波电路,确保信号传输稳定。

五、使用注意事项

为保证性能与安全,需注意:

  1. 极性识别:铝电解为有极性器件,通过引脚长度(长脚为正)或电容体“+”标记确认正负极,反接会导致爆炸;
  2. 焊接规范:手工焊接温度≤260℃,时间≤5秒;批量生产避免回流焊温度过高(遵循艾华推荐曲线);
  3. 电压限制:工作电压不得超35V DC,交流电压需核算峰值;
  4. 存储条件:常温干燥(20±5℃、湿度≤60%)存储,避免阳光直射,存储期1~2年,长期存储后需复测性能。

该电容凭借艾华的品质管控与实用设计,成为中低压电路滤波/储能的高性价比选择,可满足多场景的可靠性需求。

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
