AISHI ERK2G9220F16OT 直插铝电解电容产品概述

一、产品核心规格参数

AISHI(艾华集团)ERK2G9220F16OT为径向直插铝电解电容,核心规格针对中高压电路需求优化,关键参数如下:

  • 容值与精度:22μF,精度范围为**-40%~0%**(实际容值最低13.2μF、最高22μF,适配对容值下限有明确要求的场景);
  • 额定电压:400V(直流额定,适用于高压直流母线、开关电源输出等场景);
  • 纹波电流:100kHz频率下耐受值为200mA(默认环境温度20℃,温度变化需参考温度系数调整);
  • 尺寸与引脚:电容体直径Φ8mm、长度L16mm(不含引脚),引脚间距3.5mm(标准PCB通孔间距);
  • 寿命与温宽:工作寿命2000小时(@105℃,额定电压+额定纹波电流条件下连续工作),常规工作温度覆盖-40℃~105℃。

二、关键性能特点

该电容围绕高压滤波、储能场景设计,具备以下核心优势:

  1. 高电压稳定耐受:400V额定电压满足多数中高压电源的母线电压需求,避免过压击穿风险,适配工业、家电等高压电路;
  2. 高频纹波抑制:200mA@100kHz纹波电流耐受值,可有效滤除开关电源中的高频噪声,提升电路EMI性能,减少电磁干扰;
  3. 紧凑空间适配:Φ8mm×L16mm小尺寸设计,适合PCB布局紧凑的产品(如小型适配器、LED驱动电源),降低整机体积;
  4. 高温可靠性:105℃下2000小时寿命,优于常规常温电容,适配烤箱、变频器等高温环境应用;
  5. 负精度设计:-40%~0%精度范围,避免容值超差导致滤波效果下降,尤其适合对容值下限敏感的滤波电路。

三、典型应用场景

ERK2G9220F16OT因高压、小尺寸特性,广泛应用于以下领域:

  1. 开关电源滤波:LED驱动电源、手机/笔记本适配器的高压输出端,滤除高频纹波,稳定输出电压;
  2. 工业控制电路:PLC、变频器的直流母线滤波,抑制母线电压波动,保障控制精度;
  3. 家电控制板:空调、洗衣机的高压供电电路,提升电路可靠性,延长家电使用寿命;
  4. 通讯辅助电源:基站、路由器的中高压辅助电源,保障供电稳定性,减少设备故障;
  5. 照明设备:高压LED灯具的储能与滤波环节,提升灯具光效一致性,降低频闪风险。

四、封装与引脚说明

该电容采用径向直插封装,结构细节适配常规生产工艺:

  • 封装形式:径向引线(引脚从电容体两端垂直引出),安装方式为PCB通孔焊接;
  • 尺寸细节:电容体Φ8mm(直径)×L16mm(长度,不含引脚),引脚长度5~7mm(符合手工焊、波峰焊要求);
  • 极性标识:电容体表面印有负极条纹(铝电解为有极性器件,焊接时需严格匹配正负极,避免反向击穿);
  • 引脚材质:镀锡铜,具备良好焊接性与导电性,可兼容无铅焊接工艺。

五、可靠性与寿命评估

产品可靠性需结合实际应用条件评估,关键注意事项如下:

  • 寿命计算:105℃下2000小时为额定寿命,环境温度每降低10℃,寿命约延长2倍(如85℃下约8000小时,65℃下约32000小时);
  • 焊接要求:引脚焊接温度≤260℃(焊接时间≤10秒),避免高温损坏内部电解液;
  • 储存条件:常温(25℃±5℃)、干燥(湿度≤60%)环境下储存,最长储存时间不超过2年(储存后需复测容值与漏电流);
  • 异常防护:避免过压(超过400V)、过流(纹波电流超200mA)、过温(超过105℃)等工况,防止电解液干涸或引脚氧化。

该产品兼顾高压性能与小尺寸优势,是中高压电路滤波、储能的高性价比选择,适配多领域量产需求。

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
