EWH1CM221E11OT 直插铝电解电容产品概述

EWH1CM221E11OT是艾华集团(AISHI) 推出的一款通用型直插铝电解电容,针对中低功率电子设备的电源滤波、耦合需求设计,具备小型化、宽温适应性及稳定的纹波抑制能力,广泛适配消费电子、小型工业控制等紧凑电路场景。

一、产品核心定位与典型应用场景

该电容属于中低压通用型直插电解电容,重点解决小体积设备的电源稳定需求,典型应用场景包括:

  • 消费电子终端:机顶盒、路由器、智能手环、蓝牙耳机等小型终端的电源滤波电路;
  • 小家电控制板:电热水壶、加湿器、小型榨汁机的控制电路电源模块;
  • 小型工业模块:PLC扩展模块、传感器信号调理电路的耦合/滤波环节;
  • 小功率LED驱动:LED灯带、台灯的低压驱动电路滤波。

其16V额定电压、180mA纹波电流的参数组合,恰好匹配上述场景的中低功率、小空间需求,无需过度选型导致成本浪费。

二、关键技术参数详解

1. 容值与精度

容值为220μF,精度±20%,属于通用型电解电容的标准精度范围,满足大多数电源滤波、耦合的容值需求(无需高精度的场合)。

2. 额定电压

额定电压为16V DC,实际工作电路的直流电压需低于此值(建议留有20%余量,即工作电压不超过12.8V),避免过压导致电容漏液、失效。

3. 纹波电流能力

纹波电流额定值为180mA@120Hz,对应市电整流后的典型纹波频率(50/60Hz市电整流后为100/120Hz),可有效滤除电源中的交流纹波,稳定输出直流电压,避免纹波过大影响后端MCU、传感器等器件的正常工作。

4. 工作寿命

工作寿命为2000小时@105℃,表明电容在105℃高温环境下持续工作2000小时后,容值衰减仍符合行业标准(容值变化≤±20%,损耗角正切值达标),相比普通85℃工作温度的电解电容,更适合有一定温升的设备内部(如小家电、小型电源的密闭空间)。

三、封装与尺寸规格

该电容采用直插式封装,具体尺寸参数如下:

  • 引脚间距:2.5mm(适配标准PCB的2.5mm焊盘间距);
  • 电容体直径:6.3mm;
  • 电容体长度:11mm(不含引脚)。

尺寸属于小型化设计,可适配紧凑的PCB布局(如智能手环、蓝牙耳机的高密度电路),无需额外预留过多安装空间,提升设备集成度。

四、品牌与品质保障

艾华集团(AISHI)是国内铝电解电容领域龙头企业,产品符合GB/T 3667.1-2016《铝电解电容器 第1部分:总则》 及国际IEC 60384-1标准,具备以下品质优势:

  • 采用优质铝箔与电解液,减少漏电流,提升寿命稳定性;
  • 严格生产工艺控制,确保容值、电压等参数一致性;
  • 完善可靠性测试(高温寿命、纹波耐久性等),保障实际场景稳定性。

五、选型与应用注意事项

  1. 电压匹配:实际工作电压需低于16V(建议余量20%),禁止过压使用;
  2. 极性确认:直插电解为有极性器件,长引脚为正极,需对应PCB正极焊盘,反接会导致电容失效甚至爆裂;
  3. 纹波电流限制:电路纹波电流需小于180mA@120Hz,纹波较大时可并联电容或选更大纹波型号;
  4. 温度环境:长期工作温度不宜超过105℃,设备内部温升较高时需考虑散热;
  5. 尺寸适配:确认PCB引脚间距为2.5mm,电容体周围需预留至少1mm散热/安装空间。

综上,EWH1CM221E11OT凭借小型化、宽温适应性及稳定性能,成为消费电子、小型工业控制等领域中低压电源电路的高性价比选型。

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
