ERS1KM220F12OT 直插铝电解电容产品概述

一、产品核心身份与定位

ERS1KM220F12OT是艾华集团(AISHI) 推出的一款通用型径向引线直插铝电解电容,专为中低压电路的滤波、耦合及储能场景设计。型号命名对应明确参数:“220”代表容值22μF,“K”对应精度±20%,“M”代表额定电压100V(铝电解电容电压代码:M=100V),“12”对应电容体长度12mm,整体尺寸为φ8mm(直径)×12mm(长度),脚间距3.5mm,是工业控制、消费电子等领域的常用规格。

二、关键电气性能参数

  1. 容值与精度:标称容值22μF,精度±20%,满足大多数非精密电路需求(如普通开关电源的输出纹波抑制);
  2. 额定电压:100V DC(直流),建议实际工作电压不超过80V(留20%裕量,避免过压损坏);
  3. 工作寿命:7000小时@105℃高温环境,比市场同类基础款电容(通常5000hrs@105℃)寿命延长40%,适合24小时连续运行的工业设备;
  4. 温度特性:工作范围-40℃~+105℃,低温下容值衰减符合行业标准,高温稳定性优于普通铝电解电容。

三、机械封装与安装规格

该电容采用径向双引线封装(引脚从电容体两端垂直引出),机械参数清晰:

  • 电容体尺寸:直径φ8mm,长度12mm(不含引脚);
  • 引脚间距:3.5mm(PCB焊盘中心距);
  • 引脚材质:镀锡铜丝(直径≈0.6mm),支持手工焊接或波峰焊;
  • 封装优势:布局紧凑,适合PCB空间有限的设计(如小型机顶盒、车载电源模块),插件式安装无需特殊设备,降低生产难度。

四、品牌与品质保障

艾华集团是国内铝电解电容龙头企业,产品通过ISO9001、ISO/TS16949认证,ERS1KM220F12OT的品质管控体现在:

  • 原材料:高纯度腐蚀铝箔(提升比容)、耐温电解液(减少高温挥发与老化);
  • 生产工艺:卷绕结构紧凑,引脚与铝箔焊接牢固,避免虚焊/脱落;
  • 可靠性测试:每批次经电压老化、温度循环测试,确保出厂参数达标。

五、典型应用场景

结合参数与封装特点,核心应用包括:

  1. 电源系统:开关电源、线性电源的输出滤波(配合10μF陶瓷电容滤高频纹波,22μF电解滤低频纹波);
  2. 工业控制:PLC、变频器的辅助电源滤波,或继电器驱动电路储能;
  3. 消费电子:显示器电源模块、机顶盒信号滤波、音频功放耦合电容;
  4. 车载电子:12V/24V车载电源滤波(覆盖-40℃~+85℃车载环境)。

六、选型与替换注意事项

  1. 电压裕量:实际工作电压≤80V,若峰值接近100V,建议升级160V规格;
  2. 寿命匹配:若设备长期超105℃,需换长寿命型号(如10000hrs@105℃);
  3. 替换兼容性:同参数(22μF±20%、100V、φ8×12mm、脚距3.5mm)的Rubycon、Nichicon等品牌可直接替换,需确认引脚焊接兼容性。

总结

ERS1KM220F12OT凭借稳定性能、可靠寿命及紧凑封装,成为中低压电路的高性价比选择,适合对成本敏感且需长期稳定运行的设备设计。

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
