ERS1HM4R7D11OT 直插铝电解电容产品概述

一、产品核心定位

ERS1HM4R7D11OT是艾华集团(AISHI)推出的径向引线直插铝电解电容,专为中低压电子电路的滤波、耦合、旁路等核心功能设计。其以50V额定电压、4.7μF容值为核心参数,兼顾体积紧凑性与高温可靠性,适配从消费电子到工业控制的多场景应用需求,是中小功率电路的高性价比选择。

二、关键电气性能参数

  1. 容值与精度:标称容值4.7μF,公差±20%,满足通用电路对容值偏差的常规要求,无需额外匹配高精度元件,降低电路设计复杂度;
  2. 额定电压:50V直流额定电压,覆盖常见电源(12V、24V、48V系统)及信号电路的电压等级,留有10%-20%的安全余量,避免电压波动导致的电容失效;
  3. 工作寿命:5000小时@105℃,是普通常温电容(通常1000hrs@85℃)的5倍,可应对长期高温运行场景(如工业控制柜、车载辅助系统);
  4. 电气稳定性:铝电解电容固有低ESR(等效串联电阻)特性(艾华产品行业常规水平),可有效抑制高频纹波,提升电源输出质量与信号传输清晰度。

三、机械结构与封装规格

  1. 封装类型:径向引线直插封装,引脚垂直于电容体,兼容手工焊接与自动插件工艺,适合中小批量及量产需求;
  2. 尺寸参数:电容体直径(D)5mm、长度(L)11mm,体积仅约0.21cm³,适配小型化设备(智能小家电、微型控制器)的空间限制;
  3. 引脚设计:脚间距2mm,符合大多数PCB板的标准焊盘间距(如0805封装焊盘间距1.6mm,2mm无需特殊布局),降低板级设计成本。

四、可靠性与环境适应性

  1. 高温耐受性:105℃工作温度上限,可应对工业现场(控制柜内)、夏季户外设备的温度波动,避免电容性能快速衰减;
  2. 寿命稳定性:5000hrs@105℃的寿命指标,意味着持续高温运行下,容值衰减、漏电流增加等失效模式概率显著降低,减少设备维护频次;
  3. 极性防护:铝电解电容的极性设计(需注意正负极匹配),可避免反向电压损坏,提升电路抗干扰能力与长期稳定性。

五、典型应用场景

  1. 小型电源模块:12V/24V开关电源的输出滤波,50V额定电压为电压波动留冗余,4.7μF容值抑制高频纹波;
  2. 音频电路:功放、收音机的耦合电容,传递音频信号时减少失真,适配低功率音频系统;
  3. 工业控制单元:PLC、传感器模块的信号滤波,105℃高温寿命适配工业现场环境;
  4. 消费电子:智能手表、蓝牙耳机的辅助电源滤波,体积小巧不影响整机设计。

六、品牌与品质保障

艾华集团是国内铝电解电容龙头企业,产品通过ISO9001、ISO/TS16949认证,ERS1HM4R7D11OT具备批次一致性好、稳定性高的特点,适合量产应用。其生产工艺符合RoHS环保标准,满足欧盟等地区的环保要求,可提供完整的质量追溯体系。

该产品以“高性价比+可靠性”为核心优势,覆盖多场景需求,是中小功率电路设计的优选元件。

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
