EWH1HM221G13OT 产品概述

一、产品简介

EWH1HM221G13OT 是 AISHI(艾华集团)出品的一款直插式铝电解电容,标称容量 220µF,额定电压 50V,±20% 容差。电容体尺寸小巧(直径 10mm × 长度 13mm),脚距 5mm,适用于空间受限的插件电路板。该型号专为工业级电源滤波与旁路设计,工作温度范围宽(-40℃ 至 +105℃),在 105℃ 下额定寿命 2000 小时。

二、主要规格

  • 品牌:AISHI(艾华集团)
  • 型号:EWH1HM221G13OT
  • 容值:220µF ±20%
  • 额定电压:50V DC
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 hrs @ 105℃
  • 纹波电流:300mA @ 120Hz
  • 外形尺寸(电容体):直径 D = 10mm,长度 L = 13mm
  • 引脚间距:5mm(中心距)
  • 封装:插件(D10xL13mm)

三、功能特性与优势

  • 小体积高容量:10×13mm 的紧凑封装在有限空间内提供 220µF 的容量,适合小型电源模块。
  • 宽温特性:-40℃ 至 +105℃ 的工作温度,满足大部分工业电子环境需求。
  • 中等纹波能力:300mA@120Hz,适合一般直流滤波与去耦应用。
  • 插件封装:便于手工或波峰焊装配,适用于测试板和传统插件生产线。

四、电气与机械注意点

  • 极性标识:为铝电解电容,注意安装时极性不能颠倒,负极通常有标识条。
  • 热敏性:虽能在高温下工作,但长期在高温环境会加速电解液衰减,应在散热设计上给予考虑。
  • 纹波与温升:工作纹波电流会引起温升,应评估实际频率与电流情况,必要时并联多个电容或选用更高纹波能力器件。

五、可靠性与寿命建议

  • 额定寿命 2000 小时是在 +105℃ 下的加速寿命评估;在实际应用中,降低工作温度会显著延长寿命(工程经验:温度每下降 10℃,寿命可成倍增长,但具体值需以实测为准)。
  • 长期储存或长时间停电后再投入使用,可能需要进行充电恢复(reforming)以恢复电容性能。
  • 避免长时间在超过额定温度或过高纹波条件下工作,以免漏电流增加、容量衰减或寿命缩短。

六、典型应用场景

  • 开关电源输入/输出滤波与储能
  • 模拟电路与放大器电源旁路
  • 工业控制板、仪表电源滤波
  • 通信设备与嵌入式系统的电源稳压及去耦

七、PCB 与安装建议

  • PCB 布局:保持电容与噪声源或整流桥的距离尽可能近以降低寄生感抗,减小回流面积。
  • 孔径与固位:根据脚距 5mm 设计安装孔并预留一定焊盘面积,孔壁或底部留有焊膏/焊锡填充空间以保证牢固接触。
  • 焊接工艺:遵循厂商推荐的插件焊接工艺,控制波峰或手工焊接时的加热时间,避免对电容体直接过热。安装后留有适当间距以利散热。

八、储存与采购提示

  • 储存条件:建议干燥、阴凉环境,避免高温高湿。长期储存前应按厂商建议密封包装。
  • 检验与替换:采购时确认批次与制造日期;若库存时间较长,使用前检查外观(无鼓包、泄漏)并做简单电气测试。
  • 订购信息:产品型号 EWH1HM221G13OT,封装 D10xL13mm,品牌 AISHI。批量采购可联系供应商确认供货周期与质量认证(如需 RoHS 或特定测试报告请事先说明)。

如需该器件的等效替代、PCB 参考脚位图或在特定电源设计中的应用建议(例如并联数目、去耦策略),我可以基于具体电路条件给出更详细的工程建议。

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
