ERM1KM220E12OT直插铝电解电容产品概述

ERM1KM220E12OT是艾华集团(AISHI)推出的工业级径向直插铝电解电容,专为低压直流滤波、能量存储等场景设计,兼具紧凑体积与长寿命可靠性,可满足多数工业、消费电子及车载电路的应用需求。

一、品牌背景与产品定位

艾华集团作为国内铝电解电容领域的核心厂商,拥有数十年专业研发与制造经验,产品覆盖消费电子、工业控制、新能源、车载等多领域。ERM1KM220E12OT定位为中端实用型电容,既兼顾性能可靠性,又控制成本,适合批量应用于对寿命、温度适应性有一定要求的电路设计。

二、关键电气参数解析

该电容的核心电气参数明确了其应用边界:

  1. 容值与精度:标称容值22μF,精度±20%,满足一般滤波、耦合电路的容值误差要求,无需额外高精度匹配;
  2. 额定电压:100V DC,覆盖多数低压直流电源(如24V、48V系统的滤波环节),使用时建议预留1.2~1.5倍电压余量,避免过压损坏;
  3. 寿命与温度特性:10000小时@105℃(高温额定寿命),意味着在105℃环境下可连续稳定工作约1年(按每天24小时计算),远超普通民用级电容(通常2000~5000hrs@105℃),适合高温工况场景。

三、封装与物理特性

ERM1KM220E12OT采用径向引线封装,物理尺寸紧凑,便于PCB布局:

  • 电容体尺寸:直径(D)6.3mm,长度(L)12mm,属于小型化直插电容,适合空间受限的PCB设计;
  • 引脚间距:2.5mm,匹配标准插件焊盘规格,焊接工艺兼容性强;
  • 引脚类型:径向直插,引脚为镀锡铜质,抗氧化性好,焊接牢固度高。

四、可靠性与环境适应性

除高温寿命外,该电容的可靠性体现在:

  • 温度范围:结合艾华同类产品特性,可覆盖-40℃~105℃的宽温范围,适应不同地域及工况;
  • 振动耐受性:径向封装结构稳定,可承受一般工业环境的振动(如设备运行时的轻微振动),避免引脚断裂或电容体松动;
  • 耐湿性:采用密封铝壳结构,有效阻隔湿气侵入,降低电解液干涸风险,延长实际使用寿命。

五、典型应用场景

基于参数特性,ERM1KM220E12OT适用于以下场景:

  1. 开关电源滤波:AC-DC或DC-DC转换电路中的输出滤波,稳定直流电压纹波;
  2. LED驱动电源:低压直流驱动电路的滤波与能量存储,保障LED亮度稳定;
  3. 工业控制电路:PLC、变频器等设备的电源模块,适应工业环境的温度与振动;
  4. 车载电子:12V/24V车载系统的辅助电源滤波(如车载音响、仪表盘电路),满足车载高温工况;
  5. 消费电子:电视、显示器等设备的电源板滤波,兼顾成本与可靠性。

六、选型与应用注意事项

为保障电容性能与寿命,应用时需注意:

  1. 电压余量:工作电压需低于80V(100V×0.8),避免长期过压导致电解液分解;
  2. 焊接工艺:波峰焊温度不超过260℃,焊接时间不超过10秒;手工焊接温度控制在350℃以下,避免过热损坏电容体;
  3. 储存条件:未焊接电容需存放在常温(25℃±5℃)、干燥(湿度≤60%)环境,储存期不超过12个月;
  4. 极性识别:铝电解电容为极性电容,需严格对应PCB上的正负极标识,反接会导致电容损坏甚至爆炸。

ERM1KM220E12OT凭借艾华的可靠品质、紧凑体积与长寿命特性,成为众多电路设计中平衡性能与成本的优选直插铝电解电容之一。

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
