ERS1EM221E11OT直插铝电解电容产品概述

ERS1EM221E11OT是AISHI(艾华集团) 推出的径向直插铝电解电容,针对紧凑型电子设备的低压滤波、储能需求设计,具备小体积、长寿命、高可靠性等核心特点,广泛适配消费电子、工业控制及车载辅助电路等场景,是平衡设备空间、性能与成本的优选型号。

一、产品核心身份与定位

该型号属于艾华通用型铝电解电容序列,核心定位为**「低压小体积长寿命铝电解」**:

  • 既满足25V直流电路的耐压需求,覆盖多数低压电子系统;
  • 又通过6.3mm直径×11mm长度的紧凑尺寸,适配对PCB空间敏感的设备(如智能穿戴、小型家电);
  • 105℃高温下5000小时的工作寿命,兼顾环境适应性与长期稳定性,避免设备长期运行中的电容失效风险。

二、关键电性能参数

1. 容值与精度

标称容值220μF,精度±20%,符合铝电解电容通用精度标准——无需额外高精度设计即可满足滤波、耦合、储能等基础功能需求,适配多数消费电子、工业模块的常规电路设计。

2. 额定电压

25V直流额定电压,与常见低压电源系统(如5V/12V输出电源)完美匹配,避免过压击穿风险,同时电压等级覆盖80%以上的低压电子设备应用场景。

3. 纹波耐受能力

结合艾华铝电解的工艺优化,具备良好的纹波电流耐受特性(行业常规参数),可有效抑制电源电路中的电压波动,提升负载端(如MCU、传感器)的工作稳定性。

三、机械结构与封装特性

1. 封装形式

采用径向引线插件封装,兼容波峰焊、手工焊等传统电子焊接工艺,降低生产难度与设备投入成本,适配中小批量生产场景。

2. 尺寸规格

  • 电容体:直径6.3mm × 长度11mm(行业小体积铝电解范畴);
  • 脚间距:2.5mm(标准插件焊盘间距);
  • 优势:显著减少PCB占用面积,适配智能音箱、行车记录仪等紧凑型设备的空间限制。

3. 引脚设计

引线采用镀锡铜质材料,焊接牢固性好、耐腐蚀性强,避免长期使用中出现引脚氧化、虚焊问题,提升电路可靠性。

四、可靠性与环境适应性

1. 高温寿命

工作寿命5000hrs@105℃——105℃是工业设备、车载环境的常见高温上限,该指标意味着电容在高温下可稳定工作超过5000小时,大幅降低设备长期运行中的故障概率。

2. 温度范围

支持**-40℃~+105℃** 宽温范围(基于艾华电容工艺延伸),适配北方户外设备(低温)、工业烤箱周边电路(高温)等极端环境。

3. 耐湿性能

采用密封铝壳+橡胶塞工艺,有效防止电解液泄漏与水汽侵入,提升电容在潮湿环境(如家电、户外辅助电路)下的使用寿命。

五、典型应用场景

该型号因参数与尺寸的匹配性,广泛应用于以下领域:

  1. 消费电子:机顶盒、路由器、智能音箱的电源滤波电路(小体积适配设备小型化);
  2. 工业控制:小型PLC、传感器模块的辅助电源(105℃寿命适配工业温度波动);
  3. 车载电子:车载充电器、行车记录仪的低压辅助电路(耐温+小体积适配车载空间);
  4. LED驱动:小功率LED灯具的驱动滤波(25V电压匹配多数LED驱动输出)。

六、品牌背书与选型优势

1. 品牌实力

AISHI(艾华集团)是国内铝电解电容龙头企业,具备完善的研发、生产体系,产品符合IEC、RoHS等国际标准,质量管控严格,通过多项行业认证。

2. 标准化适配

封装尺寸与脚间距为行业通用规格,可直接替换同参数竞品,降低设计改模成本与采购风险。

3. 供应稳定性

艾华具备大规模产能,可满足批量采购需求,避免因缺货影响项目进度,适配OEM/ODM企业的生产计划。

综上,ERS1EM221E11OT凭借「小体积+长寿命+高适配性」的核心优势,成为低压电子电路中铝电解电容的高性价比选择,可有效平衡设备性能与成本需求。

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
