LKMD3001H471MF 直插铝电解电容产品概述

一、产品基本信息

LKMD3001H471MF为永铭(Ymin)品牌旗下的直插铝电解电容,采用径向引线封装,电容体规格为φ8mm×L30mm(直径8mm、长度30mm)。该产品针对中低压滤波、储能场景设计,适配工业控制、消费电子、通信设备等多领域的电源电路需求,是一款兼顾可靠性与成本优势的通用型电解电容。

二、核心电气性能参数

该电容的关键电气指标明确且稳定,可满足多数应用场景的精度与电压要求:

  • 容值与精度:标称容值470μF,精度±20%,符合工业级设备对容值偏差的常规需求,无需额外校准即可适配电源滤波、耦合等场景;
  • 额定电压:直流额定电压50V,可支持中低压电路长期稳定工作,避免过压击穿风险;
  • 温度特性:工作温度范围为-40℃~+105℃,覆盖常规工业与消费电子的环境温度区间;
  • 漏电流:低漏电流设计,实际漏电流≤235μA(符合0.01×C×V的行业标准),可有效降低电路功耗,提升系统稳定性。

三、物理结构与尺寸规格

电容的物理设计兼顾紧凑性与可靠性,细节如下:

  • 电容体:采用铝壳封装,外壳表面平整,底部设有防爆纹(安全设计),可在过压、过温时释放内部压力,防止爆裂;
  • 引脚:径向引出镀锡铜引脚,引脚中心距3.5mm,适配常规PCB焊盘布局,引脚预留长度符合插件焊接工艺要求;
  • 整体尺寸:电容体直径8mm、长度30mm,无额外散热结构,可直接贴装于PCB板,节省设备内部空间。

四、可靠性与工作寿命

该电容的可靠性设计突出,核心寿命参数为10000hrs@105℃,即:在环境温度持续105℃的严苛工况下,电容仍能保持容值偏差≤±20%、漏电流≤标准值的稳定性能,工作时长不低于10000小时。此参数远超普通电解电容(一般1000~5000hrs@105℃),适合长期高温运行的工业设备(如变频器、PLC)。

此外,电容具备良好的纹波电流耐受能力,可满足开关电源输入/输出滤波的纹波抑制需求,避免因纹波过大导致的电路不稳定。

五、典型应用场景

结合电气与可靠性参数,LKMD3001H471MF广泛应用于以下场景:

  1. 开关电源滤波:作为电源输入/输出端的滤波电容,抑制电压波动,提升电源质量;
  2. 工业控制设备:PLC、变频器、伺服驱动器等设备的电源电路,适配工业环境的高温、高可靠性要求;
  3. 消费电子电源:电视机、显示器、机顶盒等终端设备的电源模块,满足常规工作温度下的长期使用;
  4. 通信设备:基站、路由器、交换机等设备的辅助电源电路,支持稳定的信号传输;
  5. 车载辅助电路:部分车载非核心电路(如车载音响、照明),适配-40℃~+85℃的常规车载温度范围。

六、选型与使用注意事项

为确保电容性能稳定、延长使用寿命,需注意以下要点:

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即≤40V),避免长期接近额定电压导致老化加速;
  2. 极性安装:电解电容为极性器件,安装时需严格对应正负极(长脚为正、短脚为负,或外壳标注“+”端),反接会导致电容损坏甚至爆裂;
  3. 温度控制:避免设备内部温度长期超过105℃,可通过散热片、风扇等方式优化环境温度;
  4. PCB布局:焊盘尺寸需匹配3.5mm引脚间距,焊接时避免引脚受力弯曲,防止电容体与引脚连接处断裂;
  5. 储存条件:建议在25℃、湿度≤60%的干燥环境下储存,储存期不超过2年,长期储存后使用前建议进行老化测试。

该产品凭借稳定的电气性能、可靠的高温寿命与紧凑的尺寸,成为中低压电源电路的优选电解电容之一,可满足多数工业与消费电子场景的实际需求。

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.
