ERR1HM471W20OT直插铝电解电容产品概述

ERR1HM471W20OT是艾华集团(AISHI)推出的一款通用型直插铝电解电容,针对中高压、中等容值的电路滤波、耦合及储能需求设计,兼具体积紧凑、可靠性高、宽温适应性等特点,广泛应用于工业控制、家电、电源等领域。

一、产品核心定位与典型应用场景

该电容定位为工业级通用直插铝电解电容,核心满足三类典型场景需求:

  1. 电源系统滤波:如开关电源、线性电源的输出滤波,抑制电压纹波,稳定直流输出(适配220V转36V/48V等中压电源系统);
  2. 工业控制电路:PLC、变频器、伺服驱动器等设备的辅助电源滤波,耐受工业环境的温度波动与振动;
  3. 家电与消费电子:电视、空调、洗衣机等产品的电源模块,兼顾成本与可靠性,满足批量生产需求。

二、关键技术参数深度解析

ERR1HM471W20OT的参数设计平衡了性能与成本,核心参数如下:

  • 容值与精度:标称容值470μF,精度±20%,符合工业级电容的通用精度要求,覆盖多数滤波场景的容值需求;
  • 额定电压:50V DC,适用于工作电压≤33V(留1.5倍安全裕量)的电路,避免过压损坏;
  • 尺寸规格:电容体直径12.5mm、长度20mm,脚距5mm(标准插件间距),体积紧凑(约2.45cm³),适配小型化设备的PCB布局;
  • 寿命特性:2000小时@105℃高温环境,按Arrhenius加速寿命公式(温度每降低10℃,寿命翻倍),常温25℃下寿命可达约12万小时,满足长期连续工作需求;
  • 温区范围:典型工作温度为-40℃~105℃,覆盖工业与车载的宽温场景(如北方户外设备、高温车间)。

三、结构设计与可靠性优势

ERR1HM471W20OT采用艾华集团成熟的铝电解电容结构设计,核心优势体现在:

  1. 精密卷绕工艺:阳极箔(高纯铝)与阴极箔的卷绕间隙均匀,确保容值一致性,降低ESR(等效串联电阻),提升纹波抑制能力;
  2. 耐温电解液配方:采用低挥发、高稳定性电解液,减少高温下的电解液损耗,延长寿命;
  3. 密封结构优化:铝壳与橡胶塞的卷边密封工艺,有效防止漏液、防潮,提升环境适应性;
  4. 振动耐受设计:内部元件固定牢固,可耐受10g(10-2000Hz)的振动环境,满足工业设备的振动要求。

四、品牌背书与品质保障

艾华集团(AISHI)是国内铝电解电容行业的龙头企业,产品通过ISO9001质量管理体系、ISO/TS16949汽车行业认证,ERR1HM系列电容的品质管控贯穿全流程:

  • 原材料筛选:采用进口高纯铝箔、优质电解纸,确保基础性能;
  • 生产过程全检:每批次电容经过容量、漏电流、损耗角正切等参数检测;
  • 高温老化筛选:成品经105℃高温老化测试,剔除早期失效产品,提升可靠性。

五、安装与选型注意事项

为确保电容性能稳定,需注意以下要点:

  1. 安装要求:插件脚距匹配PCB焊盘(建议5±0.2mm),焊接温度控制在波峰焊260℃/3s以内、手工焊350℃/2s以内,避免过热损伤橡胶塞;
  2. 选型原则:额定电压需留1.2-1.5倍裕量(如实际工作电压30V,选50V足够);若需更高精度(如±10%),可选择艾华同系列高精度型号;
  3. 存储条件:常温干燥环境(温度20±5℃,湿度<60%),存储时间不超过12个月;开封后尽快使用,避免电解液挥发影响性能。

综上,ERR1HM471W20OT直插铝电解电容凭借可靠的性能、紧凑的体积与艾华集团的品质保障,是工业控制、电源、家电等领域的高性价比选择。

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
