艾华EWH2WM220W20OT直插铝电解电容产品概述

一、产品核心身份与基本定位

EWH2WM220W20OT是艾华集团(AISHI) 推出的一款工业级直插铝电解电容,属于其EWH系列长寿命产品线。该产品针对高温、高电压场景设计,兼顾可靠性与紧凑体积,广泛适配工业电源、家电控制、LED驱动等领域的需求,是替代传统低寿命电容的优选方案。

二、关键性能参数详解

2.1 电气核心参数

  • 容值与精度:标称容值22μF,精度±20%——铝电解电容受温度、频率影响较大,此精度符合工业级应用的实际需求,无需额外高精度补偿即可满足滤波、储能功能;
  • 额定电压:450V DC——远高于220V市电整流后的310V直流电压(含纹波峰值),预留充足安全余量,避免过压损坏;
  • 工作寿命:2000hrs@105℃——在105℃高温环境下连续工作2000小时后,容值变化≤±20%、损耗角正切值≤初始值1.5倍、漏电流≤初始值2倍,远超普通电容(1000hrs@105℃)的寿命标准,适合长期高温运行的设备。

2.2 物理尺寸规格

  • 电容体尺寸:直径12.5mm×长度20mm——紧凑圆柱设计,适配设备内部有限空间;
  • 引脚间距:5mm——符合PCB标准插件间距,便于布局与自动化组装;
  • 引脚类型:径向引线(两端垂直引出)——焊接性好,耐振动性能优于轴向引线,适合工业设备的机械应力场景。

三、封装与引脚设计特点

  1. 径向引线封装优势:引脚从电容体两端垂直引出,无需弯曲即可直接插入PCB焊盘,减少组装工序;同时,垂直引脚的机械稳定性更高,可降低运输、使用过程中的引脚断裂风险;
  2. 尺寸兼容性:12.5mm直径、20mm长度的电容体,与同规格电容的安装孔位完全兼容,可直接替换旧型号电容,无需修改PCB设计;
  3. 引脚材质:镀锡铜芯——镀锡层提升焊接性(润湿时间短、焊点牢固),铜芯保证导电性能,长期使用无氧化、接触不良问题。

四、典型应用场景

EWH2WM220W20OT的高电压、长寿命特性,使其适配以下场景:

  • 工业电源领域:开关电源高压侧滤波(整流后310V直流滤波)、变频器辅助电源储能;
  • 家电控制领域:空调外机变频板、洗衣机高压驱动模块(应对夏季高温环境);
  • LED驱动领域:高压型LED路灯、工矿灯驱动电源的滤波环节;
  • 通信设备领域:基站辅助电源、光纤设备的直流滤波;
  • 汽车电子领域:车载充电桩辅助电源(若满足车规要求,可用于部分商用车场景)。

五、产品可靠性与品牌优势

  1. 艾华品牌背书:艾华集团是国内铝电解电容龙头企业,拥有20余年研发生产经验,产品通过ISO9001、ISO14001、IATF16949(汽车级)等认证,供货稳定、一致性好;
  2. 可靠性设计:采用高纯度铝箔、优质电解液(耐温性好),电容体密封工艺严格,避免电解液泄漏与干燥,延长寿命;
  3. 环境适应性:除105℃高温外,还可耐受-40℃~105℃的宽温范围,适配不同地域、季节的使用环境。

该产品凭借高可靠性、宽温适配性与紧凑体积,成为工业、家电等领域高电压滤波/储能场景的实用选择,可有效降低设备维护成本与故障风险。

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
