ERS1HM331G16OT 直插铝电解电容产品概述

ERS1HM331G16OT是艾华集团(AISHI)推出的一款径向引线直插铝电解电容,针对中高压、中等容量的滤波及储能需求设计,兼具紧凑尺寸与可靠性能,广泛适配工业控制、电源模块、LED驱动等多领域应用。

一、产品基本定位

作为艾华常规系列中的经典型号,ERS1HM331G16OT定位于中低压直流电路的滤波/储能核心元件,核心解决电路中电压纹波抑制、能量临时存储问题。其参数设计兼顾“容量-电压-尺寸”平衡,既满足多数设备的电气需求,又适配小型化PCB布局,是替代传统大容量电容的高性价比选择。

二、核心电气参数详解

该电容的关键电气指标均经过严格测试,符合行业标准及艾华质量规范:

  • 容值与精度:标称330μF(标识代码“331”,即33×10¹μF),精度±20%,满足一般电子电路对容量偏差的宽容度要求,无需额外匹配高精度元件;
  • 额定电压:直流50V,可安全工作于40V以下的连续电压环境(降额使用更可靠),适配多数中压电源模块;
  • 寿命与温度:7000小时@105℃,远高于普通电容(通常2000-5000hrs@105℃),高温环境下性能衰减缓慢,适合长期运行的工业设备;
  • 等效串联电阻(ESR):基于艾华高比容阳极箔技术,ESR控制在合理范围,可有效降低纹波电压、减少电路功耗。

三、封装与机械规格

ERS1HM331G16OT采用径向引线插件封装,机械尺寸紧凑,便于PCB设计:

  • 电容体尺寸:直径10mm(D10)、长度16mm(L16),属于小型化铝电解电容范畴,可节省设备内部空间;
  • 引脚规格:脚间距5mm,引脚直径符合行业标准(0.6-0.8mm),焊接兼容性强,不易出现虚焊、假焊问题;
  • 封装类型:径向引线直插,适合传统插件工艺,无需特殊贴装设备,降低生产门槛。

四、性能与可靠性特点

  1. 高温稳定性突出:105℃下7000小时寿命,意味着在汽车电子(-40℃~105℃)、户外LED驱动等高温场景中,可连续工作数年而不失效;
  2. 容量衰减率低:在额定温度范围内,2000小时后容量衰减不超过10%(行业标准通常为15%),长期使用仍能保持滤波效果;
  3. 漏电流控制良好:出厂漏电流符合“0.01CV(μA)”标准(C为容值,V为额定电压),即最大漏电流约165μA,可减少电路静态功耗;
  4. 耐纹波能力适配:支持一定幅值的纹波电流,满足开关电源输出滤波的需求(具体值参考艾华官方 datasheet)。

五、典型应用场景

结合参数与性能,该电容适用于以下场景:

  1. 开关电源模块:输出端滤波,抑制50V以下电源的电压纹波,提升输出电压稳定性;
  2. LED驱动电源:高压侧储能/滤波,适配10-50V输出的LED驱动,高温环境下寿命优势明显;
  3. 工业控制设备:PLC、变频器、伺服驱动器的电源滤波,满足工业级可靠性要求;
  4. 消费电子:显示器、机顶盒、路由器的电源部分,紧凑尺寸适配小型化设计;
  5. 通信基站:基站电源的辅助滤波,7000小时寿命支持长期不间断运行。

六、品牌与品质保障

艾华集团(AISHI)是国内铝电解电容领域的龙头企业,产品通过ISO9001、ISO/TS16949、RoHS等认证,具备以下优势:

  • 生产工艺成熟:采用自主研发的阳极箔技术,提升电容比容与稳定性;
  • 质量管控严格:每批次产品经过全检,确保参数一致性;
  • 售后支持完善:提供技术咨询、样品申请等服务,满足客户定制化需求。

综上,ERS1HM331G16OT以“高可靠性、紧凑尺寸、高性价比”为核心优势,是中低压电路滤波/储能的理想选择,可广泛应用于多领域电子设备中。

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
