LKMC0901H470MF 直插铝电解电容产品概述

一、产品基本定位与标识

LKMC0901H470MF是永铭(Ymin)品牌推出的径向直插铝电解电容,属于小型化、中低压通用型产品。型号中:

  • “LKMC”为永铭通用电解电容系列标识;
  • “0901”对应封装尺寸代码(实际电容体直径6.3mm、长度9mm);
  • “H”代表高温适配特性(支持105℃长期工作);
  • “470”表示标称容值47μF(后两位为倍率,470=47×10⁰);
  • “MF”为电压与封装组合标识(额定电压50V)。

该产品核心定位是满足紧凑空间、中等纹波抑制、高温可靠性需求的电路设计,覆盖消费电子、工业辅助电路等场景。

二、核心电气性能参数详解

1. 容值与精度

标称容值47μF,精度公差±20%,符合铝电解电容常规精度要求,可满足大多数滤波、耦合、旁路电路的容量匹配需求,无需额外高精度校准。

2. 额定电压

额定电压50V DC,为电容安全工作电压上限。使用时需确保电路电压不超过该值,避免过压导致电容击穿、漏液或容量快速衰减。

3. 纹波电流与ESR(高频特性)

在100kHz高频条件下:

  • 耐受纹波电流:385mA(反映电容承受高频电流的能力);
  • 等效串联电阻(ESR):340mΩ(直接影响滤波效果与自身发热)。

低ESR有助于抑制输出纹波噪声,同时减少电容发热延长寿命,该参数使产品适配开关电源等高频纹波环境。

三、物理封装与尺寸规格

1. 封装类型

采用径向引线直插封装(插件式),引脚为镀锡铜质材料,焊接兼容性好,支持手工或自动焊接,适配传统PCB板设计。

2. 尺寸参数

  • 电容体直径:6.3mm
  • 电容体长度:9mm
  • 引脚间距:2.5mm

小型化设计可有效节省PCB布局空间,适配小家电、通信模块等紧凑设备的内部结构需求。

3. 极性与引脚

产品为有极性电解电容(铝电解常规特性),本体标注负极标识(如白色条纹),焊接时需严格按极性安装,反接会导致电容损坏或性能失效。

四、工作寿命与可靠性表现

1. 额定寿命

在105℃高温环境下,工作寿命可达9000小时,属于中长寿命规格。该参数表明电容在高温工况(如设备内部散热不良、夏季高温环境)下仍能稳定工作,可靠性优于普通常温寿命电容。

2. 可靠性设计

永铭采用优化的电解液配方(低挥发、高稳定性)和铝箔结构(增大有效面积),可减少长期工作中的容量衰减(≤20%/9000hrs@105℃)和漏液风险;电容本体采用阻燃外壳,符合安全标准,降低设备故障隐患。

3. 环境适应性

结合高温寿命参数,推测产品工作温度范围为**-40℃至+105℃**,可覆盖大多数民用、工业级设备的环境温度要求(如冬季低温、夏季高温环境)。

五、典型应用场景

  1. 小功率开关电源:手机充电器、LED驱动电源的输出滤波电路,利用高频纹波耐受能力抑制输出噪声,确保电源稳定。
  2. 消费电子设备:豆浆机、加湿器、机顶盒、路由器等的电源模块,小型化封装适配设备紧凑空间。
  3. 工业控制辅助电路:低功率PLC、传感器模块的辅助电源滤波,高温可靠性满足工业环境部分需求。
  4. 通信终端设备:无线耳机充电盒、小型基站模块的电源电路,兼顾容量、尺寸与纹波抑制需求。

六、品牌与品质保障

  1. 品牌背景:永铭(Ymin)是国内专注铝电解电容研发生产的企业,产品覆盖通用型、高频低阻型、长寿命型等系列,广泛应用于消费电子、工业、通信领域。
  2. 质量认证:产品符合RoHS、REACH环保指令,无有害物质;部分型号通过UL、CE安全认证,确保使用安全。
  3. 兼容性替换:参数与同规格(47μF/50V、径向直插6.3×9mm)的其他品牌电容(如红宝石、黑金刚同规格)兼容,可灵活替换。

综上,LKMC0901H470MF是一款小型化、高频适配、高温可靠的通用直插铝电解电容,适合多场景电路设计需求,是平衡性能与成本的优选方案。

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
