EWH1VM471G16OT 直插铝电解电容产品概述

一、产品基本定位与品牌背景

EWH1VM471G16OT是艾华集团(AISHI) 推出的一款常规直插铝电解电容,核心面向通用电子设备的电源滤波、储能及信号耦合场景。艾华集团作为国内铝电解电容领域的龙头企业,拥有30余年研发生产经验,产品覆盖消费电子、工业控制、通信等多领域,以“可靠性高、性价比优”为核心特点——EWH1VM471G16OT正是针对中低端通用市场设计的经典型号,适配多数低压直流电路的基础需求。

二、核心电气性能参数详解

该电容的电气参数精准匹配常规电源电路的实际需求,具体如下:

  1. 容值与精度:标称容值为470μF(型号中“471”对应47×10¹μF),精度±20%。这一容值可满足开关电源、LED驱动的输出滤波需求;±20%的精度是铝电解电容的工业级常规精度,无需额外校准即可适配非精密电路。
  2. 额定电压:35V DC(型号“V”为电压系列标识)。该电压为12V/24V等低压系统提供充足裕量,避免过压损坏(如市电整流后12V输出,35V额定电压可承受2倍以上过压风险)。
  3. 纹波电流能力:460mA(@120Hz)。纹波电流是电容在特定频率下可承受的交流电流,120Hz为市电整流后的纹波频率——460mA的能力可有效抑制电源输出波动,避免干扰后端MCU、传感器等敏感器件。
  4. 工作寿命:2000小时@105℃。该参数表明电容在高温环境(如电源内部发热区)下仍能稳定工作2000小时,符合工业级基本可靠性要求。

三、物理封装与引脚规格

EWH1VM471G16OT采用径向引线直插封装(引脚从电容体两端垂直引出),物理尺寸紧凑,具体规格:

  • 电容体直径:10mm(D10)
  • 电容体长度:16mm(L16)
  • 引脚间距:5mm

该封装的核心优势:

  1. 尺寸适配:10×16mm体积可嵌入小型化设备(如便携式充电器、智能家居控制器)的PCB布局,无空间浪费。
  2. 安装便捷:5mm标准引脚间距兼容常规PCB焊盘,支持手工焊接或自动插件,降低生产难度。
  3. 散热友好:铝外壳可辅助散热,径向引脚布局有助于热量传导至PCB,避免局部过热。

四、典型应用场景

基于参数与封装特点,该电容的典型应用包括:

  1. 开关电源:作为输出滤波电容,抑制DC-DC转换后的电压纹波,提升电源纯度。
  2. LED驱动电源:适配12V/24V LED灯带、面板灯,保障稳定供电。
  3. 家用电器:用于电视、空调、洗衣机的电源板滤波,应对日常使用的电压波动。
  4. 工业控制:PLC、变频器的辅助电源电路,承受环境温度变化(如车间高温)。
  5. 通信设备:小型基站、路由器的低压储能电容,应对瞬间负载波动(如设备启动)。

五、产品优势与市场价值

EWH1VM471G16OT的核心价值体现在“性能精准+成本可控”:

  1. 无过度设计:容值、电压等参数完全覆盖通用需求,避免成本浪费(如无需采用63V高压电容适配12V系统)。
  2. 品牌可靠性:艾华的生产工艺成熟,漏电流、损耗角正切等隐性参数符合行业标准,长期使用无鼓包、漏液风险。
  3. 性价比突出:相比进口同类电容(如日系品牌),价格低30%以上,适合批量采购的中低端厂商。

综上,EWH1VM471G16OT是一款专为通用电子设备电源系统设计的高性价比直插铝电解电容,凭借可靠性能、紧凑封装与亲民价格,成为电子工程师的常用选型之一。

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
