ERK2GM4R7F09OT 直插铝电解电容产品概述

一、产品核心定位与品牌背景

ERK2GM4R7F09OT是艾华集团(AISHI)推出的一款中高压小容值直插铝电解电容,针对工业控制、开关电源等场景的高压滤波、储能需求设计。艾华集团作为国内被动元件领域龙头企业,专注铝电解电容研发生产二十余年,产品覆盖消费电子、汽车电子、工业装备等多领域,以高可靠性、一致性著称,是众多下游厂商的核心供应商之一。

二、关键电气参数详解

该电容的核心参数直接决定应用适配性,具体解析如下:

  1. 容值与精度:标称容值4.7μF,精度±20%。这一精度满足多数工业场景(无需超高精度滤波)的需求,且批量生产一致性易控制,降低选型风险。
  2. 额定电压:400V DC(铝电解电容额定电压通常指直流耐压)。属于中高压范畴,可支撑220V/380V交流系统的直流侧应用(需注意电压降额),适配高压电路储能需求。
  3. 纹波电流能力:94mA@100kHz。纹波电流是电容高频损耗的关键指标,100kHz是开关电源典型工作频率,94mA的承受能力可避免电容因高频纹波发热加速老化,保障电路稳定。
  4. 工作寿命:2000hrs@105℃。铝电解电容寿命与温度强相关:105℃高温下可稳定工作约83天;若实际环境温度为65℃(常见工业场景),寿命可提升至约32000hrs(约3.6年),满足多数设备生命周期需求。

三、物理尺寸与封装适配

该电容采用直插式(插件)封装,尺寸紧凑,适配板级空间有限的场景:

  • 封装尺寸:电容体直径8mm(D8)、长度9mm(L9),脚间距3.5mm。小型化设计可节省PCB空间,适合高密度布局;
  • 焊接兼容性:直插封装支持手工焊接、波峰焊等工艺,3.5mm脚间距与通用PCB焊盘兼容,安装便捷。

四、典型应用场景

结合参数特性,该电容的核心应用场景包括:

  1. 中高压开关电源:小功率开关电源的输出滤波、辅助电源滤波环节,100kHz纹波能力适配开关频率,400V耐压支撑高压输出;
  2. 工业控制设备:PLC、变频器、伺服驱动器的辅助电路(如电源模块滤波),小型化尺寸适合设备内部紧凑布局;
  3. 高压LED驱动电源:高压LED驱动电路的滤波环节,400V耐压适配高压驱动需求,稳定输出纹波;
  4. 家电控制板:变频空调、高端冰箱的高压电源部分,满足家电长期稳定运行的可靠性要求。

五、选型与使用注意事项

为保障电容长期稳定工作,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过320V(额定电压的80%),避免过压击穿或寿命缩短;
  2. 纹波电流限制:电路实际纹波电流需低于94mA@100kHz,若过大需并联电容分担损耗;
  3. 温度控制:避免长期处于105℃高温,可通过PCB敷铜散热降低电容表面温度;
  4. 焊接工艺:波峰焊温度≤260℃、时间≤10s;手工焊温度≤350℃、时间≤3s,避免损伤电解液。

六、品牌品质优势

艾华ERK系列电容采用优质阳极/阴极铝箔及电解液,生产遵循ISO9001质量管理体系,产品一致性好、可靠性高。此外,艾华提供完善售后技术支持,针对批量应用可定制选型方案,降低客户研发成本。

该电容以高性价比、紧凑尺寸适配中高压小容值场景,是工业控制、电源领域的实用选型。

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
