KM1E221M0611 产品概述

一、产品简介

KM1E221M0611 是 ROQANG(容强)出品的一款直插式铝电解电容器,额定容量 220µF,额定电压 25V,容差 ±20%。该器件为径向引线(插件)封装,外形尺寸标注为 6×11mm,脚间距 2.5mm,适合传统通孔焊接与手工插件/波峰焊工艺。作为常用的中容量电解电容,适用于电源滤波、去耦与能量存储等场合。

二、主要电气参数

  • 容值:220µF,容差 ±20%
  • 额定电压:25V
  • 纹波电流:236mA(测量条件 120kHz)
  • 工作温度范围:-40℃ ~ +105℃

三、结构与封装

  • 封装形式:径向引线(插件)
  • 外形尺寸:6mm(直径)×11mm(高度)
  • 脚间距:2.5mm,适配常见直插 PCB 布局
  • 极性:有极性(铝电解),请按正负极正确插装,电容外壳或顶端通常有极性和型号标识。

四、可靠性与使用寿命

  • 额定寿命:2000 小时(测试条件 105℃)
    该寿命指在高温额定条件下的加速寿命评估。实际使用中,降低工作温度和电压应能显著延长寿命。建议常规设计中对额定电压进行适当降额(如 60–80%)并注意散热,以获得更长的可靠性。

五、典型应用场景

  • 开关电源输出滤波与输入缓冲
  • 直流稳压电源去耦与储能
  • 工业控制、通信设备与仪器仪表的电源旁路
  • LED 驱动与电源模块中的中低频纹波抑制

六、选型与实用建议

  • 纹波与并联:当电路中纹波电流高于单颗电容额定值时,可采用多颗并联分担纹波电流或改用更高额定纹波电流的型号。
  • 电压降额:为延长使用寿命,建议工作电压留有余量,避免长期在额定电压下满载运行。
  • 焊接与装配:采用通孔焊接时注意避免过高的焊接温度和过久的加热时间,必要时采用预热与局部加热措施,避免导致电容内部损伤。
  • 存储与使用:避免长时间潮湿、高温环境存放。安装前如电容已长期存放,应进行外观与泄漏电流检查。

七、总结

KM1E221M0611(ROQANG)为一款面向通用电子电源与去耦场景的径向插件铝电解电容,220µF/25V 的规格在中低电压电源滤波和储能方面具备良好的性价比。设计时注意纹波分配、降额使用与正确焊接工艺,可获得稳定可靠的长期运行表现。若需更高纹波能力或更长寿命,可咨询厂方或选用相近尺寸的高寿命/高纹波型号。

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
