AISHI EWH1AM221D11OT 直插铝电解电容产品概述

一、产品定位与基本属性

EWH1AM221D11OT是艾华集团(AISHI)推出的常规低压直插铝电解电容,属于其EWH1系列中的通用型产品。该电容针对消费电子、小型家电、低端工业控制等领域的基础电路需求设计,主打“高性价比+稳定可靠性”,可满足大多数低压电子设备的滤波、耦合、旁路等核心功能,是替代同类进口/国产通用电容的优选方案之一。

二、核心电气参数详解

该电容的参数围绕“低压、常规容值、宽温适应性”展开,具体适配场景清晰:

  1. 容值与精度:标称220μF,精度±20%——符合《GB/T 2681》通用精度要求,覆盖绝大多数民用设备滤波需求(如电源输出纹波抑制),无需高精度电容,有效控制成本。
  2. 额定电压:10V(DC)——适配5V、3.3V低压电路(路由器、机顶盒等),电压余量充足(实际工作电压远低于10V),降低过压损坏风险。
  3. 温度范围:-40℃~+105℃——支持北方户外/冷库设备低温工作,高温105℃耐受能力满足消费电子长时间温升需求(如机顶盒连续工作8小时)。

三、结构设计与封装规格

采用径向引线直插封装,结构紧凑适配常规PCB布局:

  1. 封装尺寸:电容体直径5mm(D5)、长度11mm(L11),属于小型化设计,节省PCB空间,适合智能插座、微型加湿器等小型设备高密度布局。
  2. 引脚规格:脚间距2mm——符合国内常规PCB焊盘标准,手工焊接无需特殊工具,机器插件兼容性好,提升生产效率。
  3. 结构特点:铝壳封装+橡胶密封端,防止电解液泄漏/湿气侵入;镀锡铜线引线,焊接性好,减少虚焊概率。

四、环境适应性与可靠性

艾华优化的工艺确保长期稳定:

  1. 宽温稳定性:-40℃~+105℃范围内,容值变化率≤±15%(参考产品手册);漏电流符合行业标准(25℃≤0.01CV μA,105℃≤0.03CV μA),极端温度下性能稳定。
  2. 耐老化性能:1000小时105℃老化后,容值衰减≤20%(艾华典型数据),延长设备使用寿命。
  3. 抗振动性能:径向引线+刚性封装,可承受家电搬运、汽车内轻微振动,不易出现引线断裂/内部损坏。

五、典型应用场景

基于参数特点,主要应用于:

  1. 消费电子:机顶盒、路由器、智能电视的电源滤波;LED台灯驱动耦合电容。
  2. 小型家电:加湿器、空气净化器控制板滤波;智能插座稳压电路。
  3. 低端工业控制:小型PLC辅助电源滤波;传感器模块旁路电容。
  4. 通信设备:低端交换机、无线AP电源单元滤波。

六、品牌与质量保障

艾华集团作为国内铝电解电容龙头,提供可靠保障:

  1. 认证资质:通过ISO9001/ISO14001认证,符合RoHS2.0标准(无有害物质),满足出口/环保要求。
  2. 供货与成本:常规系列供货周期1-2周,价格具市场竞争力,适合批量采购。
  3. 售后支持:提供参数选型、应用指导,批量订单可定制引线长度等参数。

该产品以“通用、稳定、低成本”为核心优势,是低压电子设备基础电路的实用选择。

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
