AISHI EWH1KM471L25OT 直插铝电解电容产品概述

一、产品基本定位与品牌背景

艾华集团(AISHI)作为国内铝电解电容领域的头部制造商,其EWH1KM471L25OT系列直插铝电解电容针对中高压、高容量滤波需求设计,属于工业级常规应用产品。该产品采用径向引线封装,尺寸紧凑,适配多数PCB布局,广泛覆盖电源、工业控制、照明等场景,是替代进口同规格产品的高性价比选项。

二、核心参数精准解析

该产品的核心参数明确匹配工业级应用的核心需求,具体如下:

  1. 容值与精度:标称容值470μF,精度±20%——满足大多数工业设备对滤波容量的需求,无需高精度场景下的额外匹配;
  2. 额定电压:100V直流额定电压——覆盖中高压电路(如AC-DC转换后的直流母线、变频器直流侧等)的电压范围,避免过压损坏;
  3. 封装尺寸:电容体直径16mm、长度25mm,径向引线脚距7.5mm——属于标准直插封装规格,便于PCB焊盘设计与自动化批量安装;
  4. 寿命指标:2000小时@105℃高温环境下的工作寿命——符合工业级设备的高温工况需求(如烤箱、高温车间的控制设备)。

三、产品设计优势

  1. 结构可靠性:采用铝电解电容经典卷绕结构,电解液配方经优化,提升高温下的容量稳定性与寿命衰减率(测试显示2000hrs@105℃下容量衰减≤20%);
  2. 安装便捷性:径向引线设计,引脚间距7.5mm适配标准PCB焊盘,焊接时无需特殊工具,适合自动化贴装或手工焊接;
  3. 电压适配性:100V额定电压填补了低电压(25V/50V)电容与高压电容(200V+)之间的缺口,可直接用于部分中高压电源模块;
  4. 尺寸紧凑性:16×25mm的封装尺寸在同容值、同电压电容中属于紧凑型,节省设备内部空间,适合小型化电源设计(如微型变频器、便携式测试仪器)。

四、典型应用场景

该产品因参数适配性强,广泛应用于以下领域:

  1. 开关电源滤波:AC-DC转换电路的输出滤波(如100V直流母线的纹波抑制)、DC-DC升压模块的输入/输出滤波;
  2. 工业控制设备:PLC(可编程逻辑控制器)的电源模块、变频器的直流侧滤波、伺服驱动器的储能电路;
  3. 照明电源:大功率LED驱动电源的滤波(如100V输入的LED路灯电源)、工业照明镇流器电路;
  4. 消费电子:部分中高压家电的电源模块(如高端变频冰箱的控制电源)、医疗设备的辅助电源(需符合常规工业级要求)。

五、可靠性与安装注意事项

  1. 寿命验证:艾华对该产品进行了严格的高温寿命测试,2000hrs@105℃下漏电流≤行业标准(≤0.01CVμA),确保长期使用稳定性;
  2. 极性要求:铝电解电容为有极性元件,安装时需严格区分正负极(长脚为正、短脚为负,或电容体侧面标注“+”极),反向连接会导致电容损坏甚至爆炸;
  3. 焊接规范:波峰焊温度建议≤260℃,焊接时间≤10秒;手工焊接温度≤350℃,时间≤3秒,避免高温损坏电容体;
  4. 储存条件:未焊接的电容需储存在温度-40℃~+85℃、相对湿度≤85%的环境中,避免阳光直射与高湿环境,储存期一般为12个月。

六、总结

EWH1KM471L25OT作为AISHI的工业级直插铝电解电容,凭借470μF/100V核心参数、2000hrs@105℃高温寿命、紧凑径向封装,成为电源、工业控制等领域的高性价比选择。其适配性强、可靠性稳定,可满足多数中高压滤波场景的需求,是设备设计中替代进口同规格产品的优质选项。

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
